Criminal justice agencies collect a variety of information and use it in multiple ways. Having a clear understanding of current realities is critical to shaping policies and improving the administration of justice. Police use data to identify hot spots; judges use it when they impose sentences; victim assistance staff use it to provide better services. The problem is that criminal justice datasets are often large, complex, and contain a wide variety of geocodes and identifiers.
Bureau Of Justice Statistics
Every year, the Bureau of Justice Statistics surveys nearly 80,000 households and over 143,000 individuals about crime victimization. What is unique about this survey is that both reported and unreported crimes data is collected. The survey has a well-documented API which offers data in the CSV, XML, and JSON formats. Let’s examine the documentation to determine how a developer could use the data in the app. The National Crime Victimization Survey (NCVS) API is split into “personal victimization” data and “household victimization” data.
