Evidence-Based Decision-Making at the Census Bureau

Evidence-Based Decision-Making at the Census Bureau

It’s the U.S. Census Bureau’s mission to measure America – our people, places, and economy.

The essential information we collect makes it possible for decision makers to understand how our country is changing. It helps the public analyze whether the nation is dedicating the right resources to the right places. And, in a critical way, it gives researchers the tools to determine what works and what needs improvement in our democracy.

The 2018 “Foundations for Evidence-Based Policymaking Act” (Public Law 115-435, “Evidence Act”) recognizes the value of evidence for government to run effectively and efficiently.

Learn more about how the Census Bureau supports evidence-building across government through our core mission, and how we measure the effectiveness of our own work.

The application process for requesting access to U.S. Census Bureau data is evolving. The Foundations for Evidence-Based Policymaking Act of 2018 calls for the Federal government to establish a standard application process (SAP) through which agencies, the Congressional Budget Office, State, local, and Tribal governments, researchers, and other individuals, as appropriate, may apply for access to confidential microdata. In response, the federal statistical system is developing the SAP Portal at www.ResearchDataGov.org. The SAP Portal is a web-based data catalog and common application that will serve as a “front door” to apply for confidential data from any of the 16 principal federal statistical agencies and units for evidence building purposes.

The SAP Portal is being developed in a phased approach. On February 28, 2022, the federal statistical agencies launched the SAP Portal data catalog to provide prospective applicants with comprehensive metadata about federal statistical agencies’ confidential microdata. On November 1, 2022, the SAP Portal will begin accepting applications to access confidential microdata.

Until the SAP Portal common application is available, explore the links below to learn more about the Census Bureau’s available data and current application process. Beginning November 1, 2022, the Census Bureau and the other principal federal statistical agencies and units will begin transitioning applications to the SAP Portal. The timeframe for transitioning applications to the SAP Portal is as follows:

  • Prior to November 1, 2022 – Use the Census Bureau’s current application process described below.
  • November 1, 2022 - December 31, 2022 – the Census Bureau will accept applications using the current application process described below or the SAP Portal common application.
  • January 1, 2023 – All application requesting access to the Census Bureau’s data should be submitted through the SAP Portal common application.  

To learn more about the SAP, please visit the Standard Application Process Overview webpage.

On January 25, 2022, ResearchDataGov was temporarily decommissioned. A new online Standard Application Process (SAP) is under development for access to all federal statistical agency restricted-use microdata. The Metadata Catalog portion of the new SAP became available on February 28, 2022 to provide prospective researchers comprehensive metadata about federal statistical agencies’ restricted-use microdata and can be found at ResearchDataGov. Later in 2022, the complete SAP will become available for researchers to submit applications for access to federal statistical agencies’ restricted-use microdata.

How Evaluation Drives In-House Program Improvement

Our evidence-building program is grounded in strong commitments from leadership and a team of evidence-focused professionals from across the agency. These include program administrators, performance managers, strategic planners, policy and budget staff, evaluators, analysts, and statisticians. They work together to ensure that we are meeting our goals and working effectively.

How Our Work Fuels Evidence-Building across Government

The Census Bureau shares its expertise so Federal, state, and local governments can better understand the populations they serve. Advances in data science allow us to safely and securely combine data sets from multiple sources. This allows us to advance the Census Bureau's mission of providing timely and unbiased data to support evidence-based decision making.
