Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
The AHHS is a national survey of housing-related hazards in the U.S. The AHHS collects environmental concentrations of lead and other contaminants in and around a nationally-representative sample of U.S. homes. The AHHS II will be the third in a series of HUD-sponsored national residential environmental health surveys; in the previous surveys, field data collection was completed in 2000 (National Survey of lead and Allergens in Housing) and 2006 (American Healthy Homes Survey). Lead-based paint and associated hazards are prevalent in U.S. housing. The predominant route for exposure for children is by ingestion of lead-contaminated dust through normal hand-to-mouth behaviors, therefore reducing the prevalence of lead-based paint hazards in housing will reduce children’s lead exposure overall as well as the number of children with elevated blood lead levels (EBLL) as defined by CDC. Reducing the number of homes with lead-based paint and residential lead-based paint hazards will reduce potential sources of lead that are the primary pathways for lead ingestion by children.
