Section 17-5 - Application of the 2012 IAR Mortality Table
In using the 2012 IAR Mortality Table, the mortality rate for a person age x in year (2012 + n) is calculated as follows:
The resulting q x 2012+n shall be rounded to three decimal places per 1,000 , e.g., 0.741 deaths per 1,000. Also, the rounding shall occur a ccording to the formula above, starting at the 2012 period table rate.
For example, for a male age 30, qx2012 = 0.741.
qx 2013= 0.741 * (1 - 0.010) ^ 1 = 0.73359, which is rounded to 0.734.
qx 2014= 0.741 * (1 - 0.010) ^ 2 = 0.7262541, which is rounded to 0.726.
A method leading to incorrect rounding would be to calculate qx 2014 as qx 2013 * (1 - 0.010), or
0.734 * 0.99 = 0.727. It is incorrect to use the already rounded qx 2013 to calculate qx 2014.
