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