Striving for health equity in health education programming in a county as large and diverse as Cook County, Illinois is no small task. Cook County is the second-most populous county in the United States after Los Angeles County, California. As of 2015, the population was 5.2 million.
Health disparities across the county, which includes the city of Chicago and its surrounding suburbs, are vast. Data show the areas of greatest disparity being the south and west sides of the city, as well as the southern suburbs.
