Oct 30 -- The Census Bureau has asked OMB to approve the design of the 2021 Survey of Income and Program Participation (SIPP) and invites the public to submit comments by December 3, 2020.
The 2021 SIPP will collect information about a variety of topics including demographics, household composition, education, nativity and citizenship, health insurance coverage, Medicaid, Medicare, employment and earnings, unemployment insurance, assets, child support, disability, housing subsidies, migration, Old-Age Survivors and Disability Insurance (OASDI), poverty, and participation in various government programs like Supplemental Nutrition Assistance Program (SNAP), Supplemental Security Income (SSI), and Temporary Assistance for Needy Families (TANF). The SIPP sample is nationally representative, with an oversample of low-income areas, in order to increase the ability to measure participation in government programs.
Starting in 2019, the Census Bureau and the Social Security Administration (SSA) entered into a joint agreement where both agencies support the SIPP program by contributing resources to add, process, review, and maintain additional content on marital history, parental mortality, retirement and pension, and disability. This joint agreement started in September 2019 and goes until September 30, 2023.

This request is for the SIPP collection starting February 2021. The Census Bureau plans to conduct the SIPP using an overlapping sample design. The Census Bureau's SIPP Computer-Assisted Personal Interviewing (CAPI) will use an Event History Calendar (EHC) interviewing method and a 12-month, calendar-year reference period. This is the same approach as the 2014 and the 2018 SIPP Panels.  
The SIPP instrument content and post-production processing will remain similar to that of the 2018 SIPP.   The SIPP instrument is currently written in Blaise and C#. It incorporates an Event History Calendar (EHC) design to help ensure that the SIPP will collect intra-year dynamics of income, program participation, and other activities with at least the same data quality as earlier panels. The EHC is intended to help respondents recall information in a more natural “autobiographical” manner by using life events as triggers to recall other economic events. For example, a residence change may often occur contemporaneously with a change in employment. The entire process of compiling the calendar focuses, by its nature, on consistency and sequential order of events, and attempts to correct for otherwise missing data.

Since the SIPP EHC collects information using this “autobiographical” manner for the prior year, due to the coronavirus pandemic, select questions were modified to include answer options related to the pandemic as well as adding new questions pertaining to the pandemic. For instance, we adjusted the question regarding being away from work part-time to include being possibly furloughed due to coronavirus pandemic business closures. We also added new questions to collect information on whether the respondent receive any stimulus payments.
The SIPP respondent universe is the civilian, noninstitutionalized population based on the 2010 decennial census, which contains approximately 303.5 million individuals. The SIPP uses a two-stage stratified sample of this universe. The first stage involves the division of the United States into groups of counties called the Primary Selection Units (PSUs), which are assembled into homogeneous groups called strata. Two PSUs are then selected from each stratum. The second stage involves selection of units within the selected PSUs.

Within each PSU, living quarters (LQs) are systematically selected from lists of addresses prepared from the 2010 decennial census. Other sampling techniques are used to represent new construction and group quarters. Low-income households are over-sampled from the lists of addresses.

The SIPP sample comes from the 2010 sample redesign. The SIPP sample is currently planned for approximately 53,000 designated LQs, it will yield approximately 42,400 designated occupied LQs at the time of interview in 2021, of which approximately 33,600 will be interviewed. Each household contains an average of 2.1 eligible respondents (aged 15 years and older), therefore, the planned SIPP sample of approximately 53,000 designated LQs, and it should contain approximately 70,560 survey respondents.
