What about similarly populated cities?

• Matsumoto, Japan
• Pleiku, Vietnam
• Puli Khumri, Afghanistan
• Al Qusiya, Egypt
• Tieling, China
• Jhunjhunu, India

In new street additions, Dinhata and Al Qusiya both built increasingly disconnected streets over time, while Matsumoto built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Dinhata had a more connected network than Al Qusiya in 1975 but the two have since reversed their relative ranking.
