Crime and Attitudes About Neighborhood Safety Where exactly does Crime data come from?  It usually comes from two general sources: observations and reports.  Crime statistics can be gathered by observing criminal activity directly, observed in terms of the response of bystanders and witnesses, generated by criminal justice agencies, and  reported by victims or offenders.  Several questions in the CCCS explore whether or not residents have been victims of  assault, burglary, larceny(personal and household), or robbery.  Additional questions in the survey examine residents' perception of the level of  crime in their community, as well as their attitudes regarding gun legislation.
