2005 Nonforeign Area Cost-of-Living Allowance Survey Report: 
Caribbean and Washington, DC, Areas

AGENCY: Office of Personnel Management.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice publishes the ``2005 Nonforeign Area Cost-of-
Living Allowance Survey Report: Caribbean and Washington, DC, Areas.'' 
The Federal Government uses the results of surveys such as these to set 
cost-of-living allowance (COLA) rates for General Schedule, U.S. Postal 
Service, and certain other Federal employees in Alaska, Hawaii, Guam 
and the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin 
Islands. This report contains the results of the COLA surveys conducted 
by the Office of Personnel Management in Puerto Rico, the U.S. Virgin 
Islands, and the Washington, DC area during the spring of 2005.

DATES: Comments on this report must be received on or before December 
26, 2006.

ADDRESSES: Send or deliver comments to Jerome D. Mikowicz, Acting 
Deputy Associate Director for Pay and Performance Policy, Strategic 
Human Resources Policy Division, Office of Personnel Management, Room 
7H31, 1900 E Street, NW., Washington, DC 20415-8200; fax: (202) 606-
4264; or e-mail: COLA@opm.gov.

FOR FURTHER INFORMATION CONTACT: Donald L. Paquin, (202) 606-2838; fax: 
(202) 606-4264; or e-mail: COLA@opm.gov.

SUPPLEMENTARY INFORMATION: Section 591.229 of title 5, Code of Federal 
Regulations, requires the Office of Personnel Management (OPM) to 
publish nonforeign area cost-of-living allowance (COLA) survey summary 
reports in the Federal Register. We are publishing the complete ``2005 
Nonforeign Area Cost-of-Living Allowance Survey Report: Caribbean and 
Washington, DC, Areas'' with this notice. The report contains the 
results of the COLA surveys we conducted in Puerto Rico, the U.S. 
Virgin Islands, and the Washington, DC area during the spring of 2005.

Survey Results

    Using an index scale with Washington, DC area living costs equal to 
100, we computed index values of relative prices in the Puerto Rico and 
U.S. Virgin Islands COLA areas. Then we added an adjustment factor of 
7.0 to the Puerto Rico price index and 9.0 to the U.S. Virgin Islands 
price index and rounded the results to the nearest whole percentage 
point. According to the results, the COLA rate for the U.S. Virgin 
Islands should increase from 23 percent, which is the current rate, to 
25 percent; and the COLA rate for Puerto Rico should decrease from 10.5 
percent, which is the current rate, to 9.5 percent. Section 591.228(c) 
limits decreases to 1 percentage point in a 12-month period. In a 
proposed rule published with this notice, OPM proposes to adjust COLA 
rate rates based on the results of the 2005 Caribbean surveys.

Executive Summary

    The Government pays cost-of-living allowances (COLAs) to Federal 
employees in nonforeign areas in consideration of living costs 
significantly higher than those in the Washington, DC area. The Office 
of Personnel Management (OPM) conducts living-cost surveys to set the 
COLA rates. The methodology for conducting these surveys is prescribed 
in regulation at subpart B of part 591 of title 5 of the Code of 
Federal Regulations.
    This report provides the results of the COLA surveys OPM conducted 
in the spring of 2005 in Puerto Rico, the U.S. Virgin Islands, and the 
Washington, DC area. The report details our comparison of living costs 
in the Caribbean areas with living costs in the Washington, DC area.
    For the surveys, we contacted about 850 outlets and collected 
approximately 4,000 non-rental prices on more than 250 items 
representing typical consumer purchases. We also collected about 1,800 
rental prices. We then combined the data using consumer expenditure 
information from the Bureau of Labor Statistics. The final results are 
living-cost indexes, shown in Table 1. These indexes compare living 
costs in Puerto Rico and the U.S. Virgin Islands to those in the 
Washington, DC area. The index for the DC area (not shown) is 100.00 
because it is, by law, the reference area. The living-cost indexes 
shown in Table 1 include the adjustment factor prescribed at 5 CFR 
591.227.

1. Introduction

1.1 Report Objectives

    This report provides the results of the 2005 ``Caribbean'' 
nonforeign area cost-of-living allowance (COLA) survey conducted by the 
Office of Personnel Management (OPM) in the spring of 2005. (Appendix 1 
lists prior survey reports and their publication dates.) In addition to 
providing the results, the report describes how we prepared for and 
conducted the survey and analyzed the results. The results show 
comparative living-cost differences between the Caribbean COLA areas, 
i.e., Puerto Rico and the U.S. Virgin Islands (USVI), and the 
Washington, DC area. By law, Washington, DC, is the base or 
``reference'' area for the COLA program.

2. Preparing for the Survey

2.1 COLA Advisory Committees

    Before conducting the Caribbean survey, OPM established COLA 
Advisory Committees (CACs) in Puerto Rico, St. Croix (USVI), and St. 
Thomas/St. John (USVI). The settlement of Caraballo, et al. v. United 
States, No. 1997-0027 (D.V.I.), August 17, 2000, provides for employee 
involvement in the administration of the COLA program. As in previous 
surveys, we found it valuable to involve employee and agency 
representatives in planning and conducting the surveys and reviewing 
the results.
    Each CAC is composed of approximately 12 agency and employee 
representatives from the survey area and 2 OPM representatives. The 
functions of the CACs include the following:

--Advising and assisting OPM in planning COLA surveys;
--Providing or arranging for data collection observers during COLA 
surveys;
--Advising and assisting OPM in reviewing survey data;
--Advising OPM on its COLA program administration, including survey 
methodology;
--Assisting OPM in disseminating information to affected employees 
about the surveys and the COLA program; and
--Advising OPM on special situations or conditions, such as hurricanes 
and earthquakes, as they relate to OPM's authority to conduct interim 
surveys or implement some other change in response to conditions caused 
by a natural disaster or similar emergency.

2.2 Pre-Survey Meetings

    To help us prepare for the COLA surveys, the CACs held 3-day 
meetings in Puerto Rico, St. Thomas, and St. Croix. The CACs reviewed 
the preliminary outlet and item lists developed by OPM for the surveys. 
The committee members researched the outlets and availability and 
appropriateness of the items in each area and made recommendations to 
us concerning the survey. We incorporated these recommendations into 
the survey design.
    We found the work of the CACs to be extremely helpful and 
informative. The CACs' knowledge of the local area, the popularity of 
items and outlets, and other information about the COLA area, were 
invaluable in helping us plan the survey.

2.3 Survey Item Selection

    As described in Sections 2.1 and 2.2, we consulted with the CACs as 
we selected survey items. We identified items to reflect a wide array 
of items consumers typically purchase. To determine what consumers 
purchase, OPM uses the Bureau of Labor Statistics (BLS) 2002/2003 
Consumer Expenditure Survey (CES). We aggregated CES expenditures into 
the following nine major expenditure groups (MEGs):

--Food,
--Shelter and Utilities,
--Household Furnishings and Supplies,
--Apparel,

[[Page 63181]]

--Transportation,
--Medical,
--Recreation,
--Education and Communication, and
--Miscellaneous.

    We further subdivided each MEG into primary expenditure groups 
(PEGs). In all, there were 45 PEGs. For example, we subdivided Food 
into the following nine PEGs:

--Cereals and Bakery Products;
--Meats, Poultry, Fish, and Eggs;
--Dairy Products;
--Fresh Fruits and Vegetables;
--Processed Foods;
--Other Food at Home;
--Nonalcoholic Beverages;
--Food Away from Home; and
--Alcoholic Beverages.

    To select survey items, we chose a sufficient number of items to 
represent each PEG and reduce overall price index variability. To do 
this, we applied the following guidelines: Each survey item should be:

--Relatively important (i.e., represent a fairly large expenditure) 
within the PEG;
--Relatively easy to find in both COLA and DC areas;
--Relatively common, i.e., what people typically buy;
--Relatively stable over time, e.g., not a fad item; and
--Subject to similar supply and demand functions.

    In all, we selected over 250 non-housing items to survey. Appendix 
2 shows how OPM organized the CES data into MEGs and PEGs, identifies 
the Detailed Expenditure Categories (DECs) for which we chose survey 
items, and shows estimated DC area middle income annual consumer 
expenditures for each DEC and higher level of aggregations.
    Appendix 3 lists the items we surveyed and their descriptions. Each 
of these items is specifically described with an exact brand, model, 
type, and size whenever practical. Thus, we priced exactly the same 
items or the same quality and quantity of items in both the COLA and DC 
areas. For example, we priced a 10.5-ounce can of Campbell's Chicken 
Noodle Soup in both the COLA and DC areas because it is typical of 
canned soups, and consumers commonly purchase it.
2.3.1 Special Considerations
    Automobile Insurance: We were not able to compare exactly the same 
level of automobile insurance coverage in all areas. State and local 
jurisdictions regulate car insurance, and the coverage offered varies 
among the Caribbean COLA areas and the Washington, DC area. Therefore, 
we surveyed different levels of automobile insurance coverage in Puerto 
Rico as compared with the USVI. However, we surveyed both levels of 
coverage, to the extent possible, in the Washington, DC area. When we 
made the price comparisons, we based the comparisons on comparable 
levels of coverage in the COLA survey area and in the DC area. Table 2 
shows the coverage we surveyed.

                 Table 2.--Automobile Insurance Coverage
------------------------------------------------------------------------
                                Puerto Rico and
           Coverage             DC area limits   USVI and DC area limits
                                and deductibles      and deductibles
------------------------------------------------------------------------
Bodily Injury................  $100,000/         $25,000/$50,000.
                                $300,000.
Property Damage..............  $25,000.........  $25,000.
Medical......................  $10,000.........  $5,000.
Uninsured Motorist *.........  $100,000/         $25,000/$50,000.
                                $300,000.
Comprehensive................  $100 Deductible.  $250 Deductible.
Collision....................  $250 Deductible.  $500 Deductible.
------------------------------------------------------------------------
* Not available in Puerto Rico or the Virgin Islands. Therefore, we
  excluded the cost of Uninsured Motorist coverage from Washington, DC
  area policies before comparing prices and computing the price index.

    Health Insurance: It is not practical to compare the prices of 
exactly the same quality and quantity of health insurance between the 
COLA and Washington, DC areas because the same array of plans is not 
offered in each area, and a significant proportion of Federal employees 
in both the COLA and DC areas subscribe to plans not available 
nationwide. To compare the employee health benefits premiums of these 
often highly different plans, OPM would have to adjust for differences 
in benefits and coverage. Research conducted by the parties prior to 
the Caraballo settlement indicated this would not be feasible.
    Therefore, OPM uses the non-Postal Service employee's share of the 
Federal Employees Health Benefits premiums by plan for each plan 
offered in each area. OPM maintains these data in its Central Personnel 
Data File (CPDF), including the number of white-collar Federal 
employees enrolled in each plan. As described in Section 4.2.3, we used 
these data to compute the average ``price'' of health insurance for 
Federal employees in the COLA and DC areas.
    Housing: For housing items, OPM surveys rental rates for specific 
kinds or classes of housing and collects detailed information about 
each housing unit. OPM surveys the following classes of housing:

--Four bedroom, single family unit, not to exceed 3200 square feet;
--Three bedroom, single family unit, not to exceed 2600 square feet;
--Two bedroom, single family unit, not to exceed 2200 square feet;
--Three bedroom apartment unit, not to exceed 2000 square feet;
--Two bedroom apartment unit, not to exceed 1800 square feet; and
--One bedroom apartment unit, not to exceed 1400 square feet.

    For each housing unit we surveyed, we obtained approximately 80 
characteristics about the unit. For example, we determined the number 
of bedrooms, bathrooms, square footage, whether there was a garage, air 
conditioning, security systems, and recreational activities. Appendix 4 
lists the types of detailed information we collected. We did not 
collect homeowner data, such as mortgage payments, maintenance 
expenses, or insurance. Under the Caraballo settlement, the parties 
agreed to adopt a rental equivalence approach similar to the one BLS 
uses for the Consumer Price Index. Rental equivalence compares the 
shelter value (rental value) of owned homes, rather than total owner 
costs, because the latter are influenced by the investment value of the 
home (i.e., influenced by what homeowners hope to realize as a profit 
when they sell their homes). As a rule, living-cost surveys do not 
compare how consumers invest their money.
    In the 2005 survey, OPM surveyed rents and used them to estimate 
homeowner rental values (i.e., rental equivalence). In late 2004 and 
2005, OPM conducted special research, the General Population Rental 
Equivalence

[[Page 63182]]

Survey (GPRES), to obtain additional rent and rental equivalence 
information. The goal was to determine whether OPM should adjust the 
rent index before using it to estimate homeowner rental values. The 
analyses showed that no adjustments should be made. Therefore, OPM's 
use of the rents to estimate rental equivalence is appropriate. OPM 
published the GPRES results in a Federal Register notice on July 31, 
2006, at 71 FR 43228.
    Although we surveyed rental rates for the same classes of housing 
in each area, the type, style, size, quality, and other 80-plus 
characteristics of each unit varied within each area and between the 
COLA and DC areas. As described in Section 4.2.6, we used special 
statistical analyses to hold these characteristics constant between the 
COLA and Washington, DC areas to make rental price comparisons.

2.4 Outlet Selection

    Just as it is important to select commonly purchased items and 
survey the same items in both the DC area and COLA areas, it is 
important to select outlets frequented by consumers and find comparable 
outlets in both the COLA and DC areas. To identify comparable outlets, 
OPM categorizes outlets by type (e.g., grocery store, convenience 
store, discount store, hardware store, auto dealer, and catalog outlet) 
and then surveys only specific items at each outlet type. For example, 
OPM surveys grocery items at supermarkets in all areas because most 
people purchase their groceries at such stores and because supermarkets 
exist in nearly all areas. Selecting comparable outlets is particularly 
important because significant price variations may occur between 
dissimilar outlets (e.g., comparing the price of milk at a supermarket 
with the price of milk at a convenience store).
    We used the above classification criteria and existing data 
sources, including previous COLA surveys, phone books, and various 
business listings, to develop initial outlet lists for the survey. We 
provided these lists to the CACs and consulted with them on outlet 
selection. The committees helped us refine the outlet lists and 
identify other/additional outlets where local consumers generally 
purchase the survey items.
    We also priced some items by catalog, and when we did, we priced 
the same items by catalog in the COLA areas and in the DC area. We 
priced 11 items by catalog in the Caribbean and DC areas. All catalog 
prices included any charges for shipping and handling and all 
applicable taxes, including excise taxes.
    In all, we surveyed prices from approximately 850 outlets. In the 
COLA survey areas, we attempted to survey three popular outlets of each 
type, to the extent practical. For some outlet types, such as local 
phone service, there were not three outlets. In some areas, there were 
not a sufficient number of businesses to find three outlets of each 
particular type. In the Washington, DC area, we attempted to survey 
nine popular outlets of each type, three in each of the DC survey areas 
described in Table 3.
    There was one major exception to this in the 2005 survey. In the 
pre-survey meetings, the Puerto Rico CAC recommended against surveying 
Amigo, one of the Puerto Rico grocery store chains. The CAC believed 
Amigo was not equivalent to the other two major chains--Grande and 
Pueblo. Therefore, we dropped Amigo from the Puerto Rico survey and 
dropped Shoppers Food Warehouse, which we believed was equivalent to 
Amigo, from the DC area survey. On the other hand, at the USVI CACs' 
advice, we surveyed several additional grocery stores in the USVI in 
anticipation that data collection and item matching would be more 
difficult there. We surveyed four grocery stores on St. Croix and five 
on St. Thomas and St. John. Because OPM compares average prices, it 
does not make any difference how many stores we survey provided we find 
the same types of stores in the COLA and DC areas.

                                of Manassas, and City of Manassas Park.
------------------------------------------------------------------------
Note: For selected items, such as golf and air travel, these survey
  areas include additional geographic locations beyond these
  jurisdictions.
* OPM collects housing data in eastern Puerto Rico and on St. John. OPM
  also collected non-housing data from selected outlets on St. John.

    OPM collected non-housing prices in outlets throughout the 
Caribbean areas described in Table 3. To collect rental data, OPM 
contracted with Delta-21 Resources, Incorporated, a research 
organization with expertise in housing and rental data collection. 
Delta-21 surveyed rental rates in locations within these areas.
    To collect non-rental data in the DC area, OPM divides the area 
into three survey areas, as shown in Table 3. OPM collects non-rental 
prices in outlets throughout these areas. As stated in the footnote to 
Table 3, we surveyed certain items, such as golf, in areas beyond the 
counties and cities specified in Table 3. Another example is air 
travel. We surveyed the cost of air travel from Ronald Reagan 
Washington National Airport, Washington Dulles International Airport, 
and Baltimore/Washington International Airport (BWI) and surveyed the 
price of a 5-mile taxi ride originating at these airports. Both Dulles 
and BWI are outside the counties and cities shown in Table 3. 
Nevertheless, DC area residents commonly use both airports.
    Delta-21 surveyed rental prices as specified in the COLA areas and 
throughout the DC area. (Note: OPM does not divide the DC area into 
three separate survey areas for rental data collection but rather 
treats the area as a single survey area.) In selecting the locations 
and sample sizes within each location, OPM used 2000 census data 
showing the relative number of Federal employees and housing units by 
zip code. In doing this, we often merged several zip codes to identify 
a single location. We allocated the rental sample objectively, 
requiring Delta to attempt to obtain more rental observations in 
locations with a relatively large number of Federal employees and 
housing units and fewer observations in locations with a relatively 
small number of Federal employees and housing units. Although the 
process provided a rational way to

[[Page 63183]]

allocate the sample, Delta was limited ultimately by how many units 
were available for rent within a location. Under the contract, Delta 
surveyed only units available for rent. It did not survey all renter-
occupied housing.

3. Conducting the Survey

3.1 Pricing Period

    OPM collected data from early March through May 2005. We collected 
non-housing price data concurrently in the Caribbean areas in March and 
collected the bulk of the DC area data in April and May. Delta-21 
collected rental data sequentially in St. Croix, St. Thomas/St. John, 
Puerto Rico, and in the Washington, DC area beginning on March 1, 2005, 
and ending on May 31, 2005.

3.2 Non-Housing Price Data Collection

3.2.1 Data Collection Teams
    In both the COLA and Washington, DC areas, OPM central office staff 
collected non-housing price data. In the COLA areas, data collection 
observers designated by the local CAC accompanied the OPM data 
collectors. Data collection observers were extremely helpful and 
advised and assisted the data collectors in contacting outlets, 
matching items, and selecting substitutes. The observers also advised 
us on other living-cost and compensation issues relating to their 
areas.
    Because of logistical considerations, cost, and the fact OPM 
central office staff is very knowledgeable about the DC area, we did 
not use CAC data collection observers in the Washington, DC area. 
However, we made all of the DC area data available to the CACs. This 
included both the rental and non-rental data. The non-rental data 
showed the individual prices by item, store, and survey location as 
well as averages. The rental data included a photograph and a rough 
sketch of the layout of the rental unit. We also provided the CACs with 
maps showing where each rental unit is located.
3.2.2 Data Collection Process
    The data collector/observer teams obtained most of the data by 
visiting stores, auto dealers, and other outlets. The teams also priced 
some items, such as car insurance, tax preparation fees, bank interest, 
and private education tuition, by telephone. As noted in Section 2.4, 
we surveyed some items via catalog, including all shipping costs and 
any applicable taxes in the price. We also collected other data, such 
as sales tax rates and airline fares, from Web sites on the Internet.
    For all items subject to sales and/or excise taxes, we added the 
appropriate amount of tax to the price before computing COLA rates. In 
the DC area, sales tax rates varied by jurisdiction, and some sales tax 
rates even varied by item within a location, such as restaurant meals 
in the Washington, DC area. Puerto Rico and the U.S. Virgin Islands 
currently have no general sales or business tax passed on to the 
consumer separately at the time of sale.
    The data collectors collected the price of the item at the time of 
the visit to the outlet. Therefore, with certain exceptions, the data 
collectors collected the sale price if the item was on sale, and we 
used sale prices in the COLA calculations. The exceptions include 
coupon prices, going-out-of-business prices, clearance prices, and 
area-wide distress sales, which we do not use because they are atypical 
and/or seasonal. We also do not collect automobile ``sale'' or 
negotiated prices. Instead, we obtain the sticker (i.e., non-
negotiated) price for the model and specified options. The prices are 
the manufacturer's suggested retail price (including options), 
destination charges, additional shipping charges, appropriate dealer-
added items or options, dealer mark-up, and taxes, including sales tax 
and licensing and title fees.

3.3 Housing (Rental) Price Data Collection

    As noted in Section 2.5, OPM contracted for the collection of 
rental data with Delta-21, which collected data in the Caribbean areas 
and in the DC area. These data included rental prices, comprehensive 
information about the size and type of dwelling, number and types of 
rooms, and other important amenities that might influence the rental 
price. Appendix 4 lists the data elements Delta-21 collected.
    The contractor identified units for rent from various sources, 
including rental property managers, realtor brokers, listing services, 
newspaper ads, grocery store bulletin boards, and casual drive-by 
observation. The contractor then visited each rental unit, took a 
photograph of the unit, made a sketch of the floor plan based on 
exterior dimensions and shape, and noted the unit's longitude and 
latitude coordinates. We used longitude and latitude to (1) determine 
the distance of the rental unit from major commercial and Government 
centers, (2) to correlate census tract data (e.g., median income) for 
the tract in which the unit was located, and (3) to map each unit's 
location. As discussed in Section 4.2.5, we used certain census tract 
data elements along with the data Delta-21 collected to determine the 
relative price of rents.

4. Analyzing the Results

4.1 Data Review

    During and after the data collection process, the data collectors 
reviewed the data for errors and omissions. This involved reviewing the 
data item-by-item and comparing prices across outlets within an area to 
spot data entry errors, mismatches, and other mistakes.
    After all of the data had been collected in both the COLA areas and 
the Washington, DC area, we again reviewed the data by item across all 
of the areas. One purpose was to spot errors not previously detected, 
but the principal reason was to look at substitute items.
    A substitute is an item similar to but not exactly the same as the 
specified survey item. For example, one of the items OPM specified was 
the 2.4GHz AT&T model 1465ESP cordless telephone. The data collectors 
in the Caribbean areas, however, discovered some stores did not carry 
this model. Therefore, the data collectors priced the 2.4GHz AT&T model 
1477 instead. We then priced the same model in the DC area and used the 
substitute price information in place of the prices of the originally 
specified item.

4.2 Special Price Computations

    After completing our data review, we made special price 
computations for five survey items: K-12 private education, Federal 
Employees Health Benefits premiums, water utilities, energy utility 
prices, and rental prices. For each of these, we used special processes 
to calculate appropriate estimates for each survey area.
4.2.1 K-12 Private Education
    One of the items OPM surveys is the average annual tuition for 
private education, grades K-12. As in previous surveys, we found 
tuition rates varied by grade level. Therefore, we computed an overall 
average tuition ``price'' for each school surveyed by averaging the 
tuition rates grade-by-grade. Section 4.4.2 below describes the 
additional special ``use factor'' OPM applied to the average tuition 
rates in the price comparison process.
4.2.2 Health Insurance
    As noted in Section 2.3.1, OPM surveyed the non-Postal employees' 
premium for the various Federal Employees Health Benefits (FEHB) plans 
offered in each survey area. Using enrollment information from the 
CPDF, we computed two weighted average premium costs--one for self-only

[[Page 63184]]

coverage and another for family coverage--for white-collar Federal 
employees in each of the COLA areas and in the Washington, DC area. As 
shown in Table 4, we then computed an overall weighted average premium 
for each survey area by applying the number of white-collar Federal 
employees nationwide enrolled in self-only and family plans. We used 
the overall weighted average premiums as ``prices'' in the price 
averaging process described in Section 4.3 below.

4.2.3 Water Utilities
    OPM surveys water utility rates in each of the COLA and Washington, 
DC, survey areas. To compute the ``price'' of water utilities, we 
assumed the average monthly water consumption in each area was 7,600 
gallons. We derived this estimate from earlier COLA research, and it 
reflects the average consumption across all of the COLA areas and the 
Washington, DC, area. We used this quantity along with the rates 
charged to compute the average monthly water utility cost by survey 
area. These average monthly costs were the water utility ``prices'' we 
used in the price averaging process described in Section 4.3 below.
    Not long after we conducted the survey, the Puerto Rico Aqueduct 
and Sewer Authority significantly increased water utility rates. 
Because of the significance of this increase, we re-priced water 
utilities in Puerto Rico and used the higher prices.
4.2.4 Energy Utilities Model
    For energy utilities (i.e., electricity, gas, and oil), OPM 
collects from local utility companies and suppliers in the COLA and DC 
survey areas the price of various energy utilities used for lighting, 
cooking, cooling, and other household needs. We use these prices in a 
heating and cooling engineering model that estimates how many kilowatt 
hours of electricity, cubic feet of gas, and/or gallons of fuel oil are 
needed to maintain a specific model home at a constant ambient 
temperature of 72 degrees in each area.
    The engineering model was developed by an economic consulting 
company under special research conducted jointly for OPM and the 
plaintiffs' representatives after the Caraballo settlement. The model 
uses local home construction information and climatic data from the 
National Oceanic and Atmospheric Administration and also includes the 
amount of electricity needed to run standard household appliances and 
lighting. For each survey area, we calculated the cost of heating and 
cooling the model home using the different heating fuels and 
electricity for lighting and appliances. Although some homes use 
additional energy sources, such as wood, coal, kerosene, and solar 
energy, we did not price or include these in the calculations because, 
based on the results of the 2000 census, relatively few homes use these 
as primary energy sources.
    For the Caribbean areas, we surveyed the price of electricity to 
compute home energy costs because the 2000 census indicated electricity 
is the primary energy source in more than 95 percent of the homes in 
Puerto Rico and the U.S. Virgin Islands. In the DC area, we surveyed 
the costs of all three fuels (gas, oil, and electricity). We used 
percentages based on the usage of the different fuels to compute a 
weighted average utility fuel cost for the DC area. Appendix 5 shows 
the energy requirements, relative usage percentages, and total costs by 
area. We used these total costs as the ``price'' of utilities in the 
COLA rate calculations.
4.2.5 Rental Data Hedonic Models
    As discussed in Sections 2.5 and 3.3, OPM hired a contractor to 
collect rental data, including rents and the characteristics of each 
rental unit. As described in Section 3.3, we collated these rental data 
with census tract information published by the Bureau of the Census 
using the longitude and latitude of the rental properties. We used 
census tracts, which are relatively small geographically, as surrogates 
for neighborhoods. We believe the census tract characteristics, such as 
the percentage of school age children, reflect the character and 
quality of the neighborhoods in which the rental units are found.
    OPM uses hedonic regression analysis, which is a type of multiple 
linear regression analysis, to compare rents in the COLA areas with 
rents in the DC area. Multiple linear regression is a type of 
statistical analysis used to determine how the dependent variable (in 
this case rent) is influenced by the independent variables (in this 
case the characteristics of the neighborhood and rental unit). In 
regression analyses, it is very important to choose the independent 
variables with great care, making certain only those meeting certain 
statistically significant thresholds are used in the analysis. To 
select the independent variables, OPM uses a special procedure 
developed jointly by OPM and economists advising OPM and the Caraballo 
plaintiffs' representatives. We call this the Variable Selection 
Protocol (VSP).
    VSP is a multi-step procedure that uses objective criteria to 
eliminate independent variables with little statistical significance in 
the regression. It also removes variables with inexplicable signs and 
variables that negatively affect the precision of the rent indexes. An 
example of an inexplicable sign is clothes washer. It had a positive 
sign in the 2005 Caribbean regression when the landlord did not provide 
it. In essence, this was the same as saying on average when the 
landlord did not provide a clothes washer, the property rented for more

[[Page 63185]]

than when the landlord provided a clothes washer. Since this is not the 
expected relationship, VSP dropped the variable.
    How VSP drops variables that negatively affect the precision of 
rent indexes is a bit more complicated to explain. The key variable in 
the regression is the survey area, i.e., Puerto Rico, St. Croix, St. 
Thomas/St. John, and the Washington, DC area. As with all variables in 
the regression, these variables have parameter estimates; but the 
survey area parameter estimates are especially important because they 
become the rent indexes for each of the survey areas. Therefore, it is 
important that the survey area parameter estimates be as accurate as 
practicable. The accuracy is measured by the standard error of the 
survey area parameter estimate. In the last steps of VSP, the protocol 
tests each of the variables in the model and drops variables that if 
retained would raise the standard errors of the survey area parameter 
estimates.
    Using VSP, we selected variables with the greatest statistical 
significance. The variables are listed below and are shown in the 
regression output in Appendix 6.

Age of unit (i.e., number of years since built or extensively 
remodeled);
Age squared;
Exceptional view (yes/no);
External condition (above average/average or below);
Microwave (yes/no);
Number of square feet combined (i.e., ``crossed'') with unit type;
Number of bathrooms
Number of bedrooms;
Percent school age children in census tract;
Percent with BA degree or higher in census tract;
Percent with BA degree squared;
Unit Type (detached house, row/townhouse, duplex/triplex/quadplex, high 
rise apartment, garden apartment, and other apartments); and
Survey area (Puerto Rico, St. Thomas/St. John, St. Croix, or the DC 
area).

    As is common in this type of analysis and as was done in the 
research leading to the Caraballo settlement, OPM uses semi-logarithmic 
regressions. As noted above in this section, the regression produces 
parameter estimates for each independent variable, including survey 
area. When the regression uses the Washington, DC area as the base, the 
regression produces parameter estimates for each of the COLA survey 
areas: Puerto Rico, St. Thomas/St. John, and St. Croix. The exponent of 
the survey area parameter estimate (i.e., after the estimate is 
converted from natural logarithms) multiplied by 100 (following the 
convention used to express indexes) is the survey area's rent index. 
This index reflects the difference in rents in each of the COLA survey 
areas relative to the Washington, DC area, while holding constant 
important neighborhood and rental unit characteristics captured in the 
survey and census data.
    OPM makes a technical adjustment in the above calculations to 
correct for a slight bias caused by the use of logarithms because the 
exponent of the average of the logarithms of a series of numbers is 
always less than the average of the numbers. Therefore, we added one-
half of the standard deviation of the survey area parameter estimate 
before converting from natural logarithms. (See Arthur Goldberger, 
``Best Linear Unbiased Prediction in the Generalized Linear Regression 
Model,'' Journal of the American Statistical Association, 1962.) Table 
6 shows the resulting rent indexes. We used these indexes as ``prices'' 
in the price averaging process described in Section 4.3.

software package.)

4.3 Averaging Prices by Item and Area

    After OPM collects, reviews, and makes special adjustments in the 
data, OPM averages the prices of each item by COLA survey area. For 
example, we priced aspirin at three different pharmacies in Puerto Rico 
and averaged these prices to compute a single average price for aspirin 
in Puerto Rico. If we collected more than one price for a particular 
matched item within the same outlet (e.g., priced equivalent brands), 
we used the lowest price by item and outlet to compute the average. 
(The concept is that if the item and brands are equivalent, consumers 
will choose the one with the lowest price.) We repeated this item-by-
item averaging process for each area.
    For Washington, DC area prices, we first averaged prices within 
each of the three DC survey areas described in Section 2.5. Then we 
computed a simple average of the three DC area survey averages to 
derive a single DC area average price for each survey item.

4.4 Computing Price Indexes

    OPM computes a price index for each of the items found in both the 
COLA survey area and in the Washington, DC area. To do this with 2005 
survey data, we divided the COLA survey area average price by the DC 
area average price and, following the convention used to express 
indexes, multiplied the result by 100. For the vast majority of survey 
items, we next applied consumer expenditure weights to combine price 
indexes. For a few items, however, OPM first applied special processes 
as described in Sections 4.4.1 and 4.4.2 below.
4.4.1 Geometric Means
    As described in Section 2.3, OPM selects survey items to represent 
specified detailed expenditure categories (DECs). Generally, OPM 
surveys only one item per DEC, but in some cases, it surveys multiple 
items at a single DEC. In these cases, it computes the geometric mean 
of the price indexes to derive a single price index for the DEC. (A 
geometric mean is the nth root of the product of n different numbers 
and is often used in price index computations.) For example, we 
surveyed two prescription drugs--Amoxicillin and Nexium in the 2005 
Caribbean survey. These two different prescription drugs represent a 
single DEC called ``prescription drugs.'' To derive a single price 
index for the DEC, we computed the geometric mean of the price index 
for Amoxicillin and the price index for Nexium.
4.4.2 Special Private Education Computations
    As noted in Section 4.2.1, OPM surveys K-12 private education in 
the COLA and DC areas and computes an average tuition ``price'' 
reflecting all grade levels. Because not everyone sends children to 
private school, OPM makes an additional special adjustment for K-12 
education by applying ``use factors.'' These use factors reflect the 
relative extent to which Federal employees make use of private 
education in the COLA and DC areas. For example, Table 8 shows a use 
factor of 4.1066 for Puerto Rico. We computed this by dividing 54.33 
percent (the percentage of Federal employees in Puerto Rico with at 
least 1 child in a private school) by 13.23 percent (the percentage of 
DC area Federal employees with at least 1 child in a private school). 
OPM obtained the percentages from the results of the 1992/93 Federal 
Employee Housing and

[[Page 63186]]

Living Patterns Survey, which is the most current comprehensive data 
available. Table 7 below shows the use factors and the adjusted price 
indexes for each COLA survey area.

----------------------------------------------------------------------------------------------------------------

4.5 Applying Consumer Expenditure Weights

    Next, OPM applies consumer expenditure weights to aggregate price 
indexes by expenditure group. As noted in Section 2.3, OPM uses the 
results of the BLS 2002/2003 Consumer Expenditure Survey to estimate 
the amounts middle income level consumers in the DC area spend on 
various items. Using expenditure weights, OPM combines the price 
indexes according to their relative importance. For example, shelter is 
the most important expenditure in terms of the COLA survey and 
represents about 30 percent of total consumer expenditures. On the 
other hand, the purchase of newspapers at newsstands represents less 
than 1/10th of 1 percent of total expenditures.
    Beginning at the lowest level of expenditure aggregation (e.g., 
sub-PEG), we computed the relative importance of each survey item 
within the level of aggregation, multiplied the price index times its 
expenditure percentage, and summed the cross products for all of the 
items within the level of aggregation to compute a weighted price index 
for the level. We repeated this process at each higher level of 
aggregation (e.g., PEG and MEG). Appendix 7 shows these calculations 
for each COLA survey area at the PEG and MEG level.
    The above process resulted in an overall price index for Puerto 
Rico (shown in Appendix 7) but not for the U.S. Virgin Islands, which 
has two separate COLA survey areas. To compute an overall price index 
for the U.S. Virgin Islands (USVI), OPM computes weights based on the 
number of General Schedule (GS) and equivalent Federal employees 
stationed on St. Croix compared with the number stationed on St. Thomas 
and St. John. OPM then multiplies each of the MEG indexes for St. Croix 
and St. Thomas/St. John by their respective GS employment weights and 
sums the cross products to produce an overall price index for the USVI. 
(See Appendix 7.) Table 8 shows the weights we used.

    Total........................................          672    100.00
------------------------------------------------------------------------

5. Final Results

    To compute the overall living-cost index, OPM adds to the price 
index a non-price adjustment factor. The parties in Caraballo 
negotiated these factors to reflect differences in living costs not 
captured by the surveys, and OPM adopted these factors in regulation as 
part of the new methodology. The factors for Puerto Rico and the U.S. 
Virgin Islands are seven and nine index points respectively. The 
resulting living-cost indexes are shown in Table 9.

6. Post Survey Meetings

    In July 2005, the St. Thomas, St. Croix, and Puerto Rico CACs held 
1-day meetings to review the survey results. We provided the committee 
members with various reports showing the data we collected, examples of 
how we reviewed these data, the data we used in our analyses, and the 
results at the PEG and MEG level, as shown in Appendix 7. We explained 
how we analyzed the rental data and used expenditure weights to combine 
price indexes to reflect overall living costs.
