EPA’s America's Children and the Environment (ACE) brings together information from a variety of curated sources to provide national trends and highlight the disproportionate impacts of environmental factors on children’s health. ACE is the EPA’s only dedicated set of children’s environmental health indicators, quantifying progress toward a healthy future for the nation’s children.

ACE provides information on how environmental factors, such as air quality, affect health outcomes like asthma rates and other conditions. ACE indicators are used to track changes over time, identify risks, and guide policy solutions to improve public health and environmental conditions in the U.S.
