What about similarly populated cities?
In new street additions, Nancheng fluctuated in its street-construction patterns, while Silopi built increasingly disconnected streets from 1975 through 1976-1990, then improved and Jetpur built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Nancheng fluctuated in connectivity, while Silopi became progressively more connected and Jetpur grew more disconnected from 1975 through 1991-2005, then improved. Notably, Nancheng had a more connected network than Silopi in 1975 but the two have since reversed their relative ranking.
