  1. Coefficients are differences in life expectancy (95% confidence intervals (CIs)), obtained from a linear mixed model of life expectancy, adjusted for the percentage of the administrative area of the city that is urbanized (Methods), with a random intercept for country, with all variables included in the same model. aVariables are defined in Methods and supplementary information. All variables are scaled by their s.d., so their coefficient is interpreted as the difference in life expectancy per s.d. increase in the variable. bCity size was log transformed and its coefficients are interpreted as the increase in life expectancy in cities that are 50% larger.
