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