More than 67 percent of all housing units in Ohio were built before 1980 and are likely to contain some lead-based paint on interior and/or exterior surfaces. Each year, approximately 160,000 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.
