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