NCVS attempts to measure “dark figure” of crime. A national representation of sample household is used to collect data, individuals or households are units of analysis, and businesses are not counted only households (Chapter 6: Measuring Crime, n.d.). “Rapes and sexual assaults are ascertained through three questions in the NCVS-1 Basic Screen Questionnaire” (Victimization Surveys, 1998).
