What about similarly populated cities?
In new street additions, Wuxi fluctuated in its street-construction patterns, while Caratinga built increasingly disconnected streets over time and Shangri-La built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Wuxi fluctuated in connectivity, while Caratinga became progressively more disconnected and Shangri-La grew more disconnected from 1975 through 1976-1990, then improved. Wuxi and Caratinga have been converging in their street-network character since 1975.
