METHODOLOGY

Justice System At-a-Glance

Justice System At-a-Glance provides a snapshot of the level of activity at different phases of the criminal justice process. This component of JSAT is based on publicly available data that are either retrieved from agency websites or provided directly by the contributing agency. The data are updated on the DC JSAT website at the same frequency with which they are updated on the contributing agency’s website.

Interactive Data

Interactive Data provides historical trends with respect to the level of activity at different phases of the criminal justice process. Contributing Agencies provide data at least annually, which is then compiled by the Statistical Analysis Center and displayed in interactive visualizations that can be filtered by geographic, temporal or demographic factors.
