In each of the 500 cities, the researchers quantified the degree of “smoking prevalence inequity” on a scale from 0 (perfect equity) to 1 (complete inequity). All cities in the study had a score of at least 0.03, representing at least a small degree of inequity, and the bulk of them had scores between 0.1 and 0.15. The most inequitable city in America was Washington, D.C., with a score of 0.23.
