What about similarly populated cities?
- Tebessa, Algeria
- Diamond Harbour, India
- Chingola, Zambia
- Chirala, India
- Bangarmau, India
- Mollar Char, Bangladesh
While Tebessa and Chirala both fluctuated in its street-construction patterns, Chizhou built increasingly disconnected streets over time in new street additions. For the full street network, though, all three cities follow the same trend. Notably, Chizhou had a more connected network than Tebessa in 1975 but the two have since reversed their relative ranking.
