The national crime survey and rape: The case of the missing question

Existing data on rape from the National Crime Survey (NCS) are of questionable value. These data are problematic because the survey never asks respondents directly whether they have been raped. As a result, it is difficult to ascertain exactly what the NCS is measuring. Nonetheless, there is some evidence that the NCS underestimates rape, thereby reinforcing the perception that rape is a rare occurrence. This paper also examines the redesign of the NCS and discusses the efficacy of the proposed changes in terms of their impact on the study of rape.
