Sampling variance estimates for SSA program recipients from the 1990 Survey of Income and Program Participation.

Since 1987 the Social Security Administration (SSA) has published a special set of tabulations on SSA program recipients in the Annual Statistical Supplement to the Social Security Bulletin using data derived from the Census Bureau's Survey of Income and Program Participation (SIPP). Estimates of sampling errors pertaining to these tabulations were derived from the 1984 SIPP panel. This article provides updated sampling error estimates for the 1990 SIPP panel to be used in conjunction with the SIPP-based tabulations provided in the Annual Statistical Supplement for 1992 and 1993. The computational approach is essentially the same as that used in the earlier analysis. Sampling variances are estimated by half-sample replication using the pseudo stratum and half-sample codes available on SIPP public use data files. Generalized tables of standard errors are provided for all SSA program participants. An appendix provides detailed specifications about the calculations. In order that it be self-contained, this article repeats much of the methodological exposition in the previous article that appeared in the October 1988 issue of the Social Security Bulletin.
