High-Risk Target Area Zip Codes


In June 2006, the Oklahoma Childhood Lead Poisoning Prevention Program (OCLPPP) was awarded a 5-year project grant “Oklahoma Childhood Lead Poisoning Prevention Program Focusing in High Risk Groups".  The program is focused on communities and populations where there is significant evidence of high numbers of children 6-72 months of age who are at high risk for lead poisoning.

In order to more effectively target high-risk areas and populations, the OCLPPP has identified 21 high-risk target area (HRTA) zip codes located within Oklahoma, Tulsa, Muskogee, Jackson, Okmulgee, Ottawa, Kay, Garfield, and Hughes counties. These 21 zip codes have been narrowed down from a list of 57 zip codes (out of approximately 700 zip codes in the state) with; 

  • greater than or equal to 22% of housing (national average) built before 1950, 
  • population of 5,000 people or higher, and 
  • greater than or equal to 18% of children under the age of 6 years (national average) living below the poverty level. 

The 57 zip codes were further compared and evaluated based on selected characteristics such as EBLL cases and proportion of minority population. Zip codes with higher EBLL prevalence and/or Hispanic comprising greater than or equal to 12.5% of the population (national average) and/or African American comprising greater than or equal to 12.3% of the population (national average) and/or American Indian comprising greater than or equal to 7.9% of the population (Oklahoma average) ranked higher and have been identified as HRTA zip codes.
