Table 7A.—Male Disabled Workers
Probability of Death
10 or more
Notes:
1. Select age denotes age last birthday at entitlement to disability benefits. Duration measured in years since selection. Attained age calculated as sum of select age and duration. Results do not include auxiliary beneficiaries payable under the DI program.
2. The value at duration t represents the probability of death—in a multiple-decrement environment—during the (t+1) year of entitlement for those originally entitled to disability benefits at select age [x] who have attained age [x]+t.
3. Select-and-ultimate table is read across the row for 0-10 years since selection, and down the last (ultimate) column for 10 or more years since selection. See table 7C for attained ages beyond age 75.
4. Results have been graduated using the Whittaker-Henderson Type B two-dimensional method.
