Justice Data Warehouse

The Justice Data Warehouse (JDW) is an integrated criminal justice data platform that connects and analyzes data from Washington State’s courts, corrections, law enforcement, and related justice agencies to provide a comprehensive view of justice system involvement and support data-driven decision-making. It is intended to support research efforts and help agencies analyze trends, improve decision-making, and coordinate activities across courts, law enforcement, and corrections systems. By providing secure and standardized access to information, it promotes transparency, accountability, and evidence-based policy development.

• The Justice Data Warehouse (JDW): Data Governance and Data Security
  The purpose of this report is to describe the data governance structure and the data security for the JDW. Through rigorous governance and review procedures, the JDW mitigates the adverse effects of poor data quality, promotes responsible and secure data management, enhances transparency, and supports data-driven policy and cross-sector collaboration. By centralizing justice data while safeguarding privacy and supporting state and local jurisdictions, the JDW plays a pivotal role in building a smarter, fairer, and more accountable justice system for Washington state.


• The Justice Data Warehouse (JDW): The Data Handbook
  The purpose of this report is to establish the Justice Data Warehouse (JDW). This integrated platform links criminal justice data from the Administrative Office of the Courts (AOC), Caseload Forecast Council (CFC), Department of Corrections (DOC), Washington State Patrol (WSP), and Washington Association of Sheriffs and Police Chiefs (WASPC), offering a comprehensive, longitudinal view of individuals’ justice system involvement. The JDW enhances transparency, supports data-driven policy, and enables collaboration across criminal justice agencies. It empowers stakeholders to identify system gaps, evaluate reforms, and design more equitable and effective justice system strategies. By centralizing criminal justice data and supporting Tribal and local jurisdictions, the JDW plays a pivotal role in building a smarter, fairer, and more accountable justice system for Washington State


• The Justice Data Warehouse (JDW): COVID-19 Metrics and Indicators
  The global 2020 coronavirus pandemic has had an unprecedented impact on the operations and actions of local, state, and national governments across all areas of criminal justice. The unique characteristics of this pandemic trend toward short- and long-term consequences as significant changes to criminal justice and legal outcomes. To respond to these impacts, the Washington Statistical Analysis Center (SAC) applied for and received the 2022 State Justice Statistics (SJS) grant from the Bureau of Justice Statistics (BJS). The SAC sought the grant to increase access to statistical data and create new metrics and indicators to enhance the integrated criminal justice database — the Justice Data Warehouse (JDW) — in efforts to strategically and analytically evaluate the pandemic’s impacts in criminal justice. Through this grant, the Washington SAC leveraged and built upon the JDW to expand the data variables by creating COVID-19 metrics and indicators to help assess and account for COVID-19 impacts in the criminal justice and legal system.

Uniform Crime Reporting

Summary Reporting System (SRS) and the National Incident-Based Reporting System (NIBRS) are part of the FBI's Uniform Crime Reporting system. SRS and NIBRS collect data on crime incidents that are reported by law enforcement agencies across the country. Because SRS and NIBRS data are collected differently, they cannot be compared.
