The National Beneficiary Survey (NBS) Public Use Files
The National Beneficiary Survey is a component of the Social Security Administration’s (SSA) evaluation of the Ticket to Work and Self-Sufficiency program (TTW). The survey is sponsored by SSA’s Office of Retirement and Disability Policy and conducted by Mathematica Policy Research (Mathematica), collected data from a national sample of Social Security Disability Insurance (DI) and Supplemental Security Income (SSI) beneficiaries and a sample of TTW participants. Mathematica conducted most interviews using computer-assisted telephone interviewing (CATI). For beneficiaries who did not respond to the CATI interview or who preferred or required an in-person interview, Mathematica followed up using computer-assisted personal interviewing (CAPI). Background, description of the surveys, sample sizes, and reports are available at NBS page. Codebooks, technical information, and public use data files are available below.
Background
The Ticket to Work and Work Incentives Improvement Act of 1999 authorized TTW. TTW is a voluntary employment program for Social Security beneficiaries with disabilities. The legislation was designed to create market-driven services to help disability beneficiaries become economically self-sufficient. Under the program, SSA provides disability beneficiaries with a “Ticket” or coupon that they may use to obtain employment-support services, including vocational rehabilitation, from an approved provider of their choice (called Employment Networks or ENs).
SSA implemented the TTW program beginning in 2002 in three phases spanning three years. Each phase corresponded to about one-third of the states. SSA is conducting a comprehensive evaluation of the TTW program and the NBS is designed to supplement that evaluation by providing information on beneficiaries’ characteristics, awareness of SSA work assistance programs, and attitudes toward work that is not otherwise available. The initial NBS survey design called for four national cross-sectional surveys (called rounds) of Ticket-eligible SSA disability beneficiaries— one each in 2004, 2005, 2006, and 2007—and cross-sectional surveys of Ticket participants in each of three groups of states (Phase 1, Phase 2, and Phase 3 states)—defined by the year in which the program was rolled out. In addition, the design called for the first TTW participant cohort in each group of Ticket roll-out states to be followed longitudinally until 2006. SSA subsequently revised this survey design to include all SSA beneficiaries with disabilities (not just those who were Ticket-eligible) and to postpone the final round of the survey to 2010 to address the experiences of TTW participants under new TTW regulations implemented by SSA in July 2008.
The NBS is intended to meet five key objectives: 1. Provide critical data on the work-related activities of SSDI and SSI beneficiaries, particularly as they relate to TTW implementation; 2. Collect data on the characteristics and program experiences of beneficiaries who use their Tickets; 3. Gather information about beneficiaries who do not use their Tickets, and the reasons they do not; 4. Collect data that will allow SSA to evaluate the employment outcomes of Ticket users and other SSDI and SSI beneficiaries; and 5. Collect data on service use, barriers to work, and perceptions about TTW and other SSA programs designed to help beneficiaries with disabilities find and keep jobs.
Though some sections of the NBS target beneficiary activity directly related to TTW, most of the survey captures more general information on SSA beneficiaries, including their disabilities, interest in work, use of services, and employment. As a result, SSA and external researchers interested in disability and employment issues can use the survey data for other policymaking and program-planning efforts.
As part of an evaluation of the TTW, Mathematica conducted the first round of the NBS in 2004. The survey included a national sample of SSA disability beneficiaries (the Representative Beneficiary Sample) and a sample of TTW participants (the Ticket Participant Sample). Mathematica collected data using computer-assisted telephone interviewing (CATI) with computer-assisted personal interviewing (CAPI) follow ups for CATI non-respondents and those who preferred or required an in-person interview to accommodate their disabilities. Additional rounds of the NBS were conducted as planned in 2005 (round 2) and 2006 (round 3). The fourth round of the NBS is planned for 2010.
Sample members in both the Representative Beneficiary Sample and the Ticket Participant Sample received the same survey instrument. The NBS collects data on a wide range of topics including employment, limiting conditions, experience with SSA programs, employment services, health and functional status, health insurance, income, and socio-demographic information. The survey instrument and other technical documents related to the NBS are available from SSA or Mathematica upon request.
Available Information
The public use files below are only for the Representative Beneficiary Samples for rounds one, two, and three. The Ticket Participant Samples are not available for public use. A relatively small proportion of SSA beneficiaries participated in the TTW program, and, as a result, the sampling rate for the Ticket Participant Samples was quite high. For this reason, SSA’s OPDR Disclosure Review Board believes releasing the participant sample would pose an unacceptable risk of disclosure for this portion of NBS survey participants.
