Criminal Justice Research Support

Incarceration cost analysis, sentencing disparity research, policing reform evaluation, and recidivism analysis using published methodologies from CCJ, Vera Institute, The Sentencing Project, and BJS.

Trellison Institute applies methodologies published by the Council on Criminal Justice (CCJ), the Vera Institute of Justice, The Sentencing Project, and the Bureau of Justice Statistics for analyzing criminal justice data. Trellison Institute has not contacted these organizations and does not claim endorsement or affiliation. We apply their published frameworks because they represent the most rigorous publicly available methods for criminal justice data analysis. CCJ's bipartisan task forces on policing and federal sentencing provide frameworks for analyzing reform outcomes. We evaluate methodology, not policy positions. Negative results are results.

What This Service Does

Criminal Justice Data Analysis

The United States incarcerates approximately 1.9 million people at an estimated annual cost exceeding $80 billion. Researchers studying incarceration economics, sentencing patterns, recidivism, and the community-level impacts of criminal justice policy need access to structured, comparable data from fragmented federal, state, and county sources.

Trellison applies published criminal justice research frameworks to publicly available data, providing researchers with clean analytical pipelines for studying these questions at the county, state, and national level.

Analytical Frameworks

Published Methodologies Applied

Vera Institute Cost-of-Incarceration Framework Published methodology for calculating the true cost of incarceration beyond per-diem rates, including healthcare, pension liabilities, capital costs, and administrative overhead.
Sentencing Project Disparity Analysis Published frameworks for measuring racial and socioeconomic disparities in sentencing, controlling for offense type, criminal history, and jurisdiction.
BJS Recidivism Measurement Bureau of Justice Statistics published methodology for tracking rearrest, reconviction, and reincarceration rates across follow-up periods and demographic groups.
Community Impact Assessment Published frameworks from the Prison Policy Initiative and academic researchers for measuring the economic impact of incarceration on families, housing stability, employment, and intergenerational outcomes.
Council on Criminal Justice Task Force Frameworks CCJ's bipartisan Task Force on Policing and Federal Sentencing Task Force provide published frameworks for analyzing policing practices, federal sentencing reform, and the impact of policy changes on public safety outcomes.
Violence Reduction & Reentry Analysis Published CCJ frameworks for evaluating community violence intervention programs and prisoner reentry initiatives, including cost-benefit analysis and outcome measurement across demographic groups.

Research Applications

Available for Verified Researchers

What researchers can do with this service

Incarceration cost modeling — county and state-level cost-of-incarceration analysis using the Vera framework, including direct costs, indirect costs, and opportunity costs.

Sentencing disparity analysis — structured data pipelines for examining sentencing outcomes across demographic groups, offense categories, and jurisdictions.

Recidivism pattern research — longitudinal analysis tools for studying rearrest and reincarceration patterns, with controls for program participation, demographics, and time-at-risk.

Community economic impact — county-level datasets linking incarceration rates to economic indicators (employment, housing, poverty, educational attainment, health outcomes).

This service is free for criminal justice researchers whose methodology passes Trellison's evaluation criteria. We provide the data infrastructure. Researchers provide the expertise and the questions. We do not advocate for specific policy positions — we measure what the data shows.
