Fig. 7: Spatiotemporal trends of the evenness of the base-period growth rate across multiple scales.
From: Does people oriented urbanization catch up with land and population urbanization

a The spatial distribution of the evenness index of the base-period growth rate in 2007, 2013, and 2020. b The evenness index of the base-period growth rate trends among regions, city sizes, and urban agglomeration division. Each center point represents the mean value, and the error bars represent the standard deviation.
