What about similarly populated cities?
In new street additions, Xinhuang built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Shwegu built increasingly disconnected streets from 1975 through 1991-2005, then improved and Jingning built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Xinhuang became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Shwegu grew more disconnected from 1975 through 1991-2005, then improved and Jingning grew more disconnected from 1975 through 1976-1990, then improved. Xinhuang and Shwegu have been growing further apart in their street-network character since 1975.
