The final results within the review had various results.[ninety seven] In 2016, there was a survey called the Countrywide Criminal offense Victimization Study DNAForensics (NCVS) which was provided by the US Bureau of Justice Data. In that study, it was observed that one.3% of people aged twelve or older were being victims of violent crimes, and eight.eighty five of households were being victims of property crimes.[ninety seven] There were some troubles with this study though.
