Probability density function of time lags between the co-location degree centrality and the second-order growth rate of the cases, a with number of confirmed cases on March 31, 2020 (red); and b with population size (orange). The error bar represents the two-side 95% confidence interval. Some counties with extreme numbers of confirmed cases are considered outliers and are not included. (Statistics of the time lags: mean: 0.6, median: 1.0, variance: 2.9, 95% confidence interval: [0.53, 0.67])
