More than 42 percent of all housing units in Ohio were built before 1950 and are likely to contain lead hazards. Ohio has approximately 3.7 million housing units containing some lead-based paint on interior and/or exterior surfaces. Each year, approximately 150,000 children from birth to 6 years of age are screened for lead poisoning in Ohio and currently, less than 3 percent are found to have confirmed elevated blood lead levels.

Data by County
Data by City*
*City is based on reported mailing address with each blood lead result. Mailing address “city” and municipal jurisdiction (local health department) are not always the same. This may cause these data to appear different than in other legitimate sources.
If you are a local health department employee who needs access to HHLPSS for case management or lead investigation activities, please contact our surveillance coordinator.
If you are an IRB-approved researcher or local health department surveillance employee who needs secure access to lead records for your work, please contact us at email@example.com. You will also need to complete and submit a Data User Agreement for our records. These can be found below.
