What about similarly populated cities?
While Candeias and Abyūhā both fluctuated in its street-construction patterns, Xiaodong built increasingly disconnected streets over time in new street additions. For the full street network, though, all three cities follow the same trend. Notably, Xiaodong had a more connected network than Candeias in 1975 but the two have since reversed their relative ranking.
