Distribution of population variables and their correlations with measles burden.

Variable names are listed in the first column along with the number of cities (n) included; the minimum (Min), median, mean, and maximum (Max) value for each variable are shown in the corresponding columns. Spearman’s rank correlation coefficient (ρ), p-value, and adjusted p-value using the Holm-Bonferroni method between each variable and the cumulative measles incidence rate (2005–2014) in cities are shown in the last three columns; variables correlated significantly with cumulative measles incidence rate at the 0.05 level after adjusted using the Holm-Bonferroni method were bolded.
