Note:
a. The impairment groups are not mutually exclusive or exhaustive. For example, there is no separate group for clients with learning disabilities.
Also, for the subgroup analysis, the PI and MI subsamples are restricted to clients age 21 and older. The CI sample includes clients 17 and older.
b. Moments for the disability insurance receipt and labor market variables are based on all person-quarters in samples. Moments for the demographic and impairment variables are based on information available in the application quarter.
