How many American homes are estimated to still contain lead paint?

The estimate that approximately 34 million American homes still contain lead paint is grounded in historical context. Lead-based paint was commonly used in homes until it was banned for residential use in 1978 due to its associated health risks, particularly in children. The prevalence of lead paint in houses built before this ban means that a significant number of older homes likely still contain it.

According to various health and environmental studies, including reports from the Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (EPA), it is projected that around 34 million homes have peeling or damaged lead-based paint, which poses a risk for lead exposure. This estimation accounts for the homes built prior to the ban where lead paint would have been used, emphasizing the ongoing public health concern regarding lead exposure and the need for lead hazard control strategies.

In contrast, lower estimates would underrepresent the potential risk associated with older housing stock, while overly high estimates could exaggerate the issue without considering extensive remediation efforts in many areas. Therefore, the approximation of 34 million provides a balanced understanding of the current lead paint situation in American homes.
