National Beneficiary Survey: Round 2 Public Use File Codebook
As part of an evaluation of the Ticket to Work and Self-Sufficiency program (TTW), Mathematica Policy Research (MPR) conducted the second round of the National Beneficiary Survey (NBS) in 2005. The survey, sponsored by the Social Security Administration’s (SSA) Office of Disability and Income Security Programs, collects cross-sectional data from a national sample of Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) beneficiaries (hereafter referred to as the Representative Beneficiary Sample) and a sample of TTW participants (hereafter referred to as the Ticket Participant Sample). The Ticket Participant Sample also includes a longitudinal component; TTW participants selected into the sample at round 1 were re-interviewed at round 2. However, to reduce the risk of disclosure, TTW participants are not included on this file.
