Healthy Illinois Survey
The Healthy Illinois (HIL) Survey is a statewide initiative led by the Illinois Department of Public Health (IDPH). It is a comprehensive annual health survey of Illinois residents with the goal of providing public health data for every county, ZIP code groupings in more highly populated areas, suburban Cook County municipalities, and Chicago community areas. The results of the survey will guide policymakers to make informed decisions on how to best use limited public health resources.

About
In 2021, Gov. JB Pritzker signed P.A. 102-0483, which requires the Illinois Department of Public Health (IDPH) to conduct a comprehensive annual survey of Illinois residents to provide robust and statistically reliable public health data for every county, ZIP code groupings in more highly populated areas, suburban Cook County municipalities, and Chicago community areas. The Healthy Illinois (HIL) Survey will examine a broad set of social determinants of health. The results of the survey will guide policymakers, including legislators, IDPH, local health departments, hospitals, and others to make informed decisions on how to best allocate limited public health resources. The first HIL Survey began in 2024.
