Provides data by county. MFJ acquires its data by approaching state and local leaders, often traveling county by county. In the process, we solicit feedback on our metrics and counsel on the limitations of the data we’re acquiring. Back in Rochester, NY, our researchers and technologists work on cleaning and coding the data, while outside auditors help to ensure the accuracy and validity of our findings. Our team also works on software automation to streamline the process of cleaning and standardizing data from disparate sources. With this combination of strategies, MFJ is able to aggregate case-level data into one central repository.

Includes a Detailed Data Tool - "An expanded data set with an interactive tool to compare state-level incarceration data for youth and adults with this expanded data set." Under U.S. Criminal Justice Data, "The Sentencing Project compiles state-level data to provide a snapshot of key indicators of mass incarceration’s impact in the United States."
