Long-Term Exposure to Fine Particulate Matter and Academic Performance Among Children in North Carolina

Elevated exposure to ambient fine particulate matter (PM2.5) has been consistently associated with adverse outcomes on children’s test scores.1 However, previous research has often relied on relatively small or less representative samples and faced challenges in accounting for unobserved confounders at the individual level.2 In this cross-sectional study, we aimed to address these limitations by employing a 2-way fixed-effects model with a large administrative data set in North Carolina.
