Approximately how many homes in the U.S. are said to still have lead-based paint?

The correct answer highlights that approximately 37 million homes in the U.S. are reported to still contain lead-based paint. This statistic is significant because it underscores the ongoing risk of lead exposure, particularly in homes built before 1978 when the federal government banned the use of lead-based paint in residential properties. Understanding the prevalence of lead-based paint is crucial for lead supervisors and health professionals, as it informs risk assessment and management strategies aimed at protecting public health, particularly for vulnerable populations like children and pregnant women. Recognizing that a substantial number of homes still harbor this hazard helps to emphasize the importance of proper lead remediation and education regarding lead exposure.
