Which statement best differentiates Official data from Unofficial data?

• A. Official data comes from law enforcement agencies; Unofficial data comes from victimization surveys or self-reporting
• B. Official data comes from victims
• C. Official data includes only property crimes
• D. Official data is always less reliable than unofficial data

Answer: (A)

The main idea here is where the data come from. Official data are produced by the criminal justice system itself—law enforcement agencies, courts, corrections—so you’ll see crime statistics based on police reports, arrest records, and formal documents. Unofficial data, on the other hand, come from sources outside the system, like victimization surveys where people are asked about crimes they experienced (even if they didn’t report them) or self-report studies where individuals disclose offenses they’ve committed or witnessed. This distinction matters because official data often undercounts crime—many incidents never make it into police records—while victimization surveys can reveal crimes that never reach police attention. Self-report data provide insight into offending and victimization that official records miss. In short, official data come from law enforcement records, whereas unofficial data come from surveys and self-reports. The other statements misstate the source or reliability of the data.
