What about similarly populated cities?
In new street additions, Qionglai built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Chibi fluctuated in its street-construction patterns and Kabwe built increasingly disconnected streets over time. For the full network, Qionglai became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Chibi fluctuated in connectivity and Kabwe became progressively more disconnected. Qionglai and Chibi have been converging in their street-network character since 1975.
