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