Effect of Asian population on site deletion status, estimated from all models meeting our admission criteria (, Area Under Curve ). These models are Models V–IX and XI–XIV (Tables 1, 2, and 4). The vertical axis shows 95% CIs for the odds ratio associated with a 1% increase in the Asian population. The shaded band highlights the overlapping region, demonstrating consistency across model specifications. These specifications vary in demographic data time periods (2000 and 2021), geographic buffers (1–4 miles), population weighting, and the inclusion of geographic effects (EPA region or state, fixed/random effects, or no adjustment). All admitted models indicate that increased Asian population around Superfund sites correlates with decreased probability of deletion (remediation), as shown by an odds ratio lower than one.
