Descriptive analysis
Ethnoracial groups lived in varying concentrations throughout the study
region—white people were overrepresented in New England (cooler
climate), and Black people were overrepresented in the South Atlantic
(warmer climate). Therefore, we first examined within-region CDDs by
state and year. For example, Figure S1 shows distinct
temperature profiles by ethnoracial groups in some states. We explored
the cooling season of 2010, the warmest in the dataset. In New York
state, white people experienced a wide distribution of exposures for
which the mean was considerably lower than for Asian, Black, and Latino
people. Other states showed more overlapping distributions but distinct
bimodal patterning, as in West Virginia, potentially due to urban/rural
development patterns. Table S1 shows population-weighted
statewide CDDs per year.
