Sensitivity analyses
In a sensitivity analysis we reran our segregation analyses using the index of concentration at the extremes as our segregation measure, where the “disadvantaged” group included Asian, Black, and Latino people as well as everyone who did not identify as white; the “privileged” group included white people (Figure S5 ). Temperatures tended to increase slightly moving from -1 (most disadvantaged people) and approaching 0 (least segregation). In all cases, moving from 0 to 1 (most white) was associated with fewer CDDs, consistent with our main analysis. We also reran our main results using varying degrees of freedom, which did not change our interpretations.
