Health Equity Starts with Data
The Chicago Health Map visualizes the prevalence of 38 chronic health conditions and firearm violence across Chicagoland neighborhoods. By making community-level health patterns visible, this platform supports residents, researchers, community organizations, and policymakers working to reduce health disparities and direct resources where they're needed most.

Health condition data presented here is available through partnership with CAPriCORN (Chicago Area Patient-Centered Outcomes Research Network), who facilitate a fully de-identified, de-duplicated, standardized clinical dataset containing healthcare visit data from over 12 million patients in the Chicagoland area. For more information about the primary data source, see the Data Methods & Resources page.
This data includes adults (age 18 and older) who:
- Visited a CAPriCORN hospital, clinic, or emergency room at least once between 2019 and 2024 and received a diagnosis of at least one health condition of interest.
- Live in one of six Chicagoland counties: Cook, DuPage, Lake, Will, Kane, or McHenry.
We track diagnosis of 38 long-term health conditions plus firearm violence. Data can be filtered by race/ethnicity, sex, age and geographic area of residence. Understanding which groups of people experience differences in health status is the first step toward building more equitable systems. See the Data Methods & Resources page for detailed definitions. Conditions include:
- Heart and blood vessel conditions: High blood pressure, heart disease, heart failure, stroke
- Breathing: Asthma, COPD
- Diabetes and related conditions: Diabetes, obesity, high cholesterol (hyperlipidemia)
- Mental health and substance use: Depression, schizophrenia, alcohol use disorder, drug use disorder
- Cancers: 13 types including lung, breast, prostate, and colon cancer
- Kidney and liver: Chronic kidney disease, liver disease, chronic hepatitis
- Blood disorders: Sickle cell disease, clotting disorders, anemia
- Brain conditions: Dementia and Alzheimer’s disease
- Firearm injuries
- Not everyone is counted. Only people who visited CAPriCORN health systems are included. People without healthcare may be missed.
- Coverage varies. Some neighborhoods have better data than others.
- Not real-time. Data is delayed by 3 to 6 months and updated once a year.
- Only diagnosed cases. People who have a condition but haven’t been diagnosed aren’t counted.
This is normal! The two websites measure health in different ways.
- Chicago Health Atlas asks people questions like “Do you have diabetes?” It counts what people say they have.
- Chicago Health Map uses medical records from doctors and hospitals. It counts what doctors have diagnosed.
