What about similarly populated cities?
While Ningyang and Jiexi both fluctuated in its street-construction patterns, Ise built increasingly disconnected streets over time in new street additions. For the full network, Ise and Ningyang both became progressively more disconnected, while Jiexi grew more disconnected from 1975 through 1976-1990, then improved. Notably, Ise had a more connected network than Jiexi in 1975 but the two have since reversed their relative ranking.
