Why Data Matters in Criminal Justice
Criminal justice professionals are turning to data to improve the system.
Crime statistics aren’t new. For years, police departments, states, and the U.S. Department of Justice have gathered and reported statistics on a wide variety of crimes. But in a world where data analytics is changing everything from political campaigns to Major League Baseball, the data we have on crime can be used for a lot more than generating statistics.
If you’re currently working a criminal justice job or if you’re considering starting a criminal justice career, data is likely to be a regular component in the coming years. That’s because an increasing number of jurisdictions are turning to data analytics. In fact, as of 2016, 120 jurisdictions—covering over 91 million people—had signed onto the Data-Driven Justice Initiative, an ambitious U.S. Department of Justice program designed to increase the use of data in multiple areas of criminal justice.1
Needless to say, if you want to succeed in a career in criminal justice, you need to understand the ways law enforcement, courts, and correctional facilities are using data to improve the system.
How It Works
Data analytics works by bringing together large amounts of data in a variety of ways in an attempt to uncover previously unseen patterns. Instead of working with one or two data points, data analytics uses the power of computer processing to bring together and correlate dozens or even hundreds of data points. In the case of the criminal justice system, data analysts can correlate criminal justice data (crime rates, recidivism rates, drug conviction numbers, etc.) with data from other sources (poverty rates, educational attainment, work history, etc.) to find patterns that can help improve the quality and efficiency of the justice system.
What It Can Achieve
Criminal justice data is making a difference in a number of areas. These include:
- Response Planning: By analyzing law enforcement decisions and outcomes when responding to thousands of crimes, criminal justice professionals can determine what response methods work best for what types of situations. With this information, law enforcement personnel can make more optimal decisions when responding to criminal acts.
- Crime Prevention: By bringing together crime data with data reflecting truancy rates, unemployment rates, incidences of vandalism, etc., law enforcement organizations can uncover both large and subtle correlations affecting crime. When these data points are geotagged, law enforcement can narrow the data further and use it to predict when and where certain types of crime are most likely to occur. In real-world usage, such data analytics have proven quite effective. For example, during a Manchester, New Hampshire, pilot program, local police used advanced data analysis to institute preventative measures that resulted in a 12% reduction in robberies, a 21% reduction in burglaries, and a 32% reduction in thefts from motor vehicles.2
- Criminal Identification: Thanks to data analytics, law enforcement agencies from across the nation can input data from crime scenes into databases designed to find connections between cases. This can help law enforcement create profiles of specific criminals and narrow suspect lists.
- Risk Assessment: In her 2013 TED Talk, former New Jersey attorney general, Anne Milgram, discussed how she has helped develop a data-driven system for determining whether a convicted criminal is likely or unlikely to pose a threat to public safety if released from jail or given probation.3 This system can help judges and parole boards make better risk assessments.
