Community Health Data

Monitoring the Health of the Community

One of the Will County Health Department’s many roles is to monitor the health of our community through

surveillance of a variety of sources of public health data. It is by tracking key indicators of health that WCHD is able to

identify trends that may pose a threat to the public and determine areas where we are making progress and where

more progress is necessary.

Improvements in public health occur only after threats are clearly identified and understood. Once that is

accomplished, real change comes as a result of actions taken by all of us as individuals and as parents, teachers,

elected officials, businesses leaders and health professionals. We all play an essential role in improving the health and

well-being of the community.

Illinois Youth Survey

About the Illinois Youth Survey (IYS)

The Illinois Department of Human Services (IDHS) has funded the administration of the Illinois Youth Survey (IYS) biennially since 1990. The IYS is a self-report survey administered in school settings and is designed to gather information about a variety of health and social indicators including substance use patterns and attitudes of Illinois youth.

The administration of the IYS has two major goals:


    • To supply local data to schools and school districts throughout Illinois. During state-funded survey years (e.g., 2018, 2020, etc.), the survey is available to all eligible public and private schools in the state at no cost. Each participating school is eligible to receive a report specific to their own students’ responses. These local reports provide critical information to school administrators, prevention professionals, and community members as they work to address substance abuse issues in their communities.
    • To provide a scientific estimate of health and social indicators for the state of Illinois. The scientific estimate is based on drawing a random sample to represent the state population of 8th, 10th, and 12th graders in Illinois public schools.
