Footnote: N=377. Disparity calculated as absolute disparity: difference between 90th and 10th population-weighted percentiles of life expectancy for each city. Each variable was entered in a separate model.
a
Log of population and median household income.
Coefficient interpretation: a 10% larger population is associated with a 0.32*log(1.1)=0.032 years wider absolute disparity between tracts at the 90th and 10th percentile of life expectancy. West is reference group for region.
MSA=Metropolitan Statistical Area.
