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