The National Crime Victimization Survey (NCVS) is an annual survey that collects data on crime against persons age 12 or older from a nationally representative, stratified, multistage cluster sample of U.S. households. The Police-Public Contact Survey (PPCS)is a supplement to the NCVS, administered to NCVS respondents age 16 or older. The Police-Public Contact Survey (PPCS) provides detailed information on the characteristics of persons who had some type of contact with police during the year, including those who contacted the police to report a crime or were pulled over in aa traffic stop. The PPCS interviews a nationally representative sample of residents age 16 or older as a supplement to the National Crime Victimization Survey. The survey enables BJS to examine the perceptions of police behavior and response during these encounters.
