The Census Bureau's Survey of Income and Program Participation (SIPP) provides data that can be used to study the characteristics of Old-Age, Survivors, and Disability Insurance (OASDI) and Supplemental Security Income (SSI) program participants. It is important that estimates of sampling errors accompany such studies because the estimates may have large sampling errors due to the small number of sample cases available for specific analyses. The generalized sampling variances provided by the Census Bureau did not identify separately either program's participants and, therefore, do not pertain directly to analyses of these groups. This article describes an approach to the direct computation of sampling variances for OASDI and SSI program participants. The approach uses the pseudo stratum and half-sample codes available in SIPP public use data files. A table of generalized standard errors is constructed for participants of both programs aged 18 or older. Generalized standard errors could not be computed for child beneficiaries under age 18 because of a wide variation of design effects across subpopulation estimates.
美国人口普查局的收入与项目参与情况调查（SIPP）提供的数据可用于研究老年、遗属和残疾保险（OASDI）以及补充保障收入（SSI）项目参与者的特征。此类研究中附带抽样误差估计很重要，因为由于可用于特定分析的样本案例数量较少，估计值可能存在较大的抽样误差。人口普查局提供的广义抽样方差并未分别识别这两个项目的参与者，因此并不直接适用于对这些群体的分析。本文描述了一种直接计算OASDI和SSI项目参与者抽样方差的方法。该方法使用SIPP公共使用数据文件中可用的伪层和半样本代码。为18岁及以上的两个项目参与者构建了一个广义标准误表。由于不同亚群体估计的设计效应差异很大，无法计算18岁以下儿童受益人的广义标准误。
