Data Analytic Recidivism Tool

The Data Analytic Recidivism Tool (DART) helps answer questions about recidivism in New York City, such as:

  • Are people that commit a certain type of crime more likely to be rearrested?
  • What about people in a certain age group or those with prior convictions?

DART is based on data compiled by the City’s Criminal Justice Agency, which tracked re-arrests for roughly 230,000 adult defendants charged with crimes in New York City in 2009 for a year after their initial arrests. Approximately 33.4 percent of defendants citywide in 2009 were arrested for a new crime within a year, with 13.2 percent of defendants arrested for a felony and 4.7 percent of defendants arrested for a violent felony. Data for additional years will be added in the future, permitting users to track re-arrest trends over time.

“Data-driven decision-making has helped us reduce crime, prevent fire fatalities and reduce detention for low-risk youth in our juvenile justice system,” said Mayor Bloomberg. “The DART application provides criminal justice policy makers and professionals with the ability to examine the data on recidivism and develop strategies that will keep New York City the safest big city in America."

DART lets users look at recidivism rates for selected groups defined by characteristics of defendants and their cases. To learn more about DART, click here.
