Numerator = Total estimate of housing units built prior to 1950
Denominator = Total estimate of housing units
Why is this important?
Houses built prior to 1950 that have not undergone substantial updates may contain hazardous materials. Lead based paint, which was banned in the United States in 1977, is a known toxin that causes nervous system damage, stunted growth and delayed development and is especially toxic to children under the age of six. Lead poisoning remains a major environmental health problem in the United States and the common source of exposure is dust from deteriorating lead paint in older homes. Homes built prior to 1950 are also likely to have asbestos insulation; the long-term inhalation of asbestos fibers is known to trigger cancer development specifically malignant mesothelioma and other lung diseases such as asbestosis.
