National Beneficiary Survey (NBS) Round Four

In 2010, we fielded the round-four NBS to two sub-samples: (1) the fourth national survey of all beneficiaries (the Representative Beneficiary Sample) and (2) a cross-sectional Ticket Participant Sample.  Originally, round four was to concentrate on following the Ticket Participant Sample interviewed in earlier rounds and on interviewing new Ticket participants in Phase 3 States.  However, the changes to the TTW regulations in 2008 made it less meaningful to track beneficiaries who participated under the old regulations.  As a result, we did not re-interview Ticket participants from previous rounds in round four.

For round four, we completed interviews with 2,298 individuals in the national sample of beneficiaries and 2,780 from the Ticket Participant Sample, for a total of 5,078 interviews completed across all sub-samples.  The weighted response rate for the Representative Beneficiary Sample was 72.8 percent. The weighted response rate for the Ticket Participant Sample was 71.4 percent.
