Nassau in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Nassau plotted against New Providence and Bahamas. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Nassau's incremental SNDi rose from 5.91 to 7.51 between 1991-2005 and 2006-2020. In terms of the aggregate network, Nassau ranked 1st out of 1 cities in New Providence and 1st out of 1 in Bahamas as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

What about similarly populated cities?

• Dharmapuri, India
• Biswan, India
• Cổ Lễ, Vietnam
• Ghent, Belgium
• Wuchuan, China
• Bule Hora, Ethiopia

In new street additions, Nassau and Dharmapuri both built increasingly disconnected streets over time, while Ghent built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Nassau and Dharmapuri have been converging in their street-network character since 1975.
