This study quantifies environmental justice disparities in PM2.5 exposure among communities surrounding John F. Kennedy International Airport in New York City. Using a buffer-based proximity analysis validated by the Airport Cooperative Research Program, PM2.5 exposure estimates were assigned to 1,042 census tracts within a 10-mile radius, ranging from 8.5 μg/m³ in areas 0-1 mile from the airport to 6.5 μg/m³ beyond 5 miles. Demographic data from the 2019-2023 American Community Survey were integrated to assess exposure disparities. Statistical analysis revealed that high-minority census tracts (>86.9% minority) experience significantly higher PM2.5 concentrations than low-minority tracts (6.79 vs. 6.55 μg/m³; p < 0.001), representing a 3.7% disparity with a medium-large effect size (Cohen's d = 0.74). Spatial Error Model regression, selected via Lagrange Multiplier diagnostics (AIC = -1,708 vs. OLS AIC = 624), confirmed that minority percentage remains a significant predictor of PM2.5 exposure (β = 0.0007, p = 0.009) after controlling for spatial autocorrelation (Moran's I = 0.93, p < 0.001). Modifiable Areal Unit Problem analysis across three spatial scales demonstrated robustness at the census tract and block group levels, but findings were not statistically significant at the coarser ZCTA scale. Local Indicators of Spatial Association identified pollution hotspots in southern Queens and the Rockaways, where 1.77 million residents in high-minority tracts face disproportionate chronic exposure. These findings document systematic environmental injustice, demonstrating that minority communities bear a disproportionate share of airport-related pollution and providing evidence for targeted mitigation and equitable policy interventions.
