Crime is public record. But it has taken our team over two years to acquire this data, convert it to useful and universal formats, identify clerical errors and duplicates, and classify the offenses into a broad and specific categories. We are now opening this up for everyone to have the opportunity to detect and understand the patterns of crime.

Our long term goal is to steer social policy in an evidence-based manner. Legal policy is often driven by intuition and politics more than by data analysis. Large-scale data analysis has the potential to reveal patterns that will assess the efficacy of legislation. Using millions of criminal records from multiple states, we mine patterns of crime and recidivism to help navigate a more effective criminal justice policy. Which policies over the past few decades have effectively reduced crime? Which types of crime respond to which types of policies? Are there “gateway crimes” that lead offenders to commit other crimes in the future? What patterns correlate with re-offense? Which crime types cluster, and which are rarely performed by the same individual? When does sentencing effectively prevent offenders from reoffending?
