A Hidden Problem: Lead-Poisoned Children in the U.S.

Lead poisoning is a preventable problem that affects children across the country. Even though we know children continue to be exposed to lead, existing data do not give us a full picture of the problem. CEHTP developed new methods and published research to estimate, for each state, how many children had lead in their bodies and how many of these children were identified. Explore the data using the interactive maps below.



For the U.S. overall, about 60% of lead-poisoned children were found. About this map.
