Combining the list-experiment and direct question to improve estimation of abortion incidence.

ABSTRACT: Abortion has been found to be severely underreported overall, and underreported differentially across groups, when using a direct question. The list-experiment method attempts to overcome these reporting biases indirectly by asking how many items an individual has experienced, but not which, where abortion is one of the items asked to a randomly-assigned 'treatment' group but not to a control group. Abortion incidence is estimated as the difference in the mean number of items reported between the treatment and control groups. If list-experiment respondents are also asked a direct abortion question, a combined-data estimator can be constructed from respondents with and without affirmative responses to the direct question. We assess for four U.S. states how this combined estimator may improv
