About This Grantee

The State Health Access Data Assistance Center (SHADAC) helps states monitor and understand trends in rates of health insurance coverage and access to care.  The Robert Wood Johnson Foundation (RWJF) provides funding for SHADAC to:

  1. Provide technical assistance to policymakers in their use of state, local and federal data on health insurance coverage;
  2. Monitor data on the number and characteristics of the uninsured; and
  3. Evaluate and work to improve the quality of state-level data on coverage.


Since 2000, SHADAC's data and survey expertise has been significant in our efforts to expand coverage. SHADAC is particularly knowledgeable about coverage data from the Current Population Survey and the American Community Survey, and it works closely with the Census Bureau on data improvement and dissemination. The project's deliverables will include reports and briefs, webinars, intensive technical assistance, convening activities, and development of SHADAC's Web-based query system as a resource for policymakers, analysts and the media.
