In the late 1980s, the U.S. Department of Housing and Urban Development (HUD) conducted a national survey of lead-based paint in housing. The EPA subsequently sponsored a comprehensive technical report on the HUD-sponsored survey to provide estimates of the extent of lead-based paint in housing. In the EPA report, a home is considered to have lead-based paint if the measured lead concentration on any painted surface is 1.0 mg/cm2 or greater. The EPA report estimates that 64 million ( 7 million) homes, or 83% ( 9%) of privately-owned housing units built before 1980, have lead-based paint somewhere in the building.

Some state and local laws define lead poisoning at higher levels than the HUD definition. Some medical works use the term lead poisoned to describe a child with a blood lead level of 10 or above.
