Color intensity increases with percent (lightest: 0.5%–0.9%, middle: 1%–1.9%, darkest: ≥2%). Outlined boxes denote children whose exposure decile was the same at their conception and birth addresses. Deciles based on 3,709 children whose mothers moved during pregnancy so all columns and rows sum to 10%.
Conception residence decile cutpoints (μg/m3): 1.38, 1.56, 1.69, 1.81, 1.93, 2.04, 2.15, 2.31, 2.53, 4.32
Birth residence decile cutpoints (μg/m3): 1.27, 1.43, 1.55, 1.66, 1.76, 1.87, 1.99, 2.13, 2.35, 4.08
