What about similarly populated cities?
In new street additions, Göttingen built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Idi-Iroko fluctuated in its street-construction patterns and Xinjin built increasingly disconnected streets over time. For the full network, Göttingen and Xinjin both became progressively more disconnected, while Idi-Iroko fluctuated in connectivity. Göttingen and Xinjin have been growing further apart in their street-network character since 1975.
