The health index was created in collaboration with the Tulsa Health Department, the Oklahoma City-County Health Department and the City of Oklahoma City Planning Office. The purpose of this index is to allow for comparisons within and between both city-county jurisdictions.

The information provides insight into the increased risk of health burdens at the zip code level that can be associated with the following factors: education, income, maternal and child health, mental health, mortality, healthcare access, crime, infectious disease and built environment. The map and table presented describe the best ranking zip codes to the lowest ranking zip codes on a scale of 1 (highest ranking) to 56 (lowest ranking).
