The Air Kids Breathe: Nearly Half of U.S. Children at Risk

A new report from the American Lung Association has found that millions of children across the United States are being exposed to dangerous levels of air pollution.

Based on data collected between 2022 and 2024, the report shows that 33.5 million children, or 46% of those under 18, live in areas that received failing grades for at least one major pollution measure, including smog and particle pollution.

The findings also indicate that 7 million children, representing 10% of the total, are living in communities that failed all three key air quality measures.

Experts warn that children are particularly vulnerable to pollution because their lungs are still developing, and they tend to breathe more air relative to their body size, especially during outdoor activities.

Exposure to polluted air has been linked to higher risks of asthma, respiratory illnesses, and long-term health complications.

The report highlights disparities as well, noting that communities of color are disproportionately affected. It also points to broader environmental and climate-related factors contributing to worsening air quality.

Researchers warn that without stronger protections and sustained efforts to reduce emissions, air pollution could continue to pose significant health risks for future generations.
