Nearly 1 in 3 New York homes carries a lead exposure risk , a 31.7% rate that is the highest of any state, roughly double the national average of 15.9%, and enough to earn New York a perfect 50 out of 50 on lead risk. An estimated 1,687,500 New York homes have serious structural problems , while approximately 2,377,500 face potential lead contamination, among the largest absolute totals of any state in the country. MethodologyData for this analysis were drawn from America’s Health Rankings, which aggregates state-level public health and housing indicators using federal survey data. The lead risk metric reflects the estimated share of housing units built before 1980 that have children present, weighted by the probability of lead exposure based on housing age and type. Each metric was converted into a 50-point proportional score, and the two scores were summed to produce a final Housing Health Risk Score out of 100.
