This report from the Vera Institute of Justice includes information about the need for greater access to policing data. It also provides an overview of Vera’s Arrest Trends online tool, initial findings gleaned from it, and potential areas for the growth and evolution of this tool. Examples of the data found include that of the 10 million arrests analyzed, only 5 percent are for serious violent crimes. Instead, the majority of arrests are for low-level offenses—including drug offenses, which have increased by 171 percent since 1980—and disproportionately impact people of color. Also, arrests of men have decreased by 7 percent since 1980 while arrests of women increased by 78 percent.
