The National Crime Victimization Survey (NCVS) Knowledge Corner provides quick tips and explanations for NCVS data users on a variety of topics. In this video, BJS Statistician Susannah Tapp, PhD, describes item nonresponse in the NCVS. Item nonresponse results in missing data. She discusses the four missing data codes used in the NCVS: residue, out of universe, item invalid until, and item invalid after.

The National Crime Victimization Survey (NCVS) Knowledge Corner provides quick tips and explanations for NCVS data users on a variety of topics. In this video, BJS Statistician Susannah Tapp, PhD, looks at person and household noninterviews in the NCVS. Household noninterviews occur when no one from a selected household participates in the NCVS. There are three types of household noninterviews – Type A, Type B, and Type C.
