Chililabombwe 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 Chililabombwe plotted against Copperbelt and Zambia. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Chililabombwe's incremental SNDi rose from 3.33 to 4.46 between 1991-2005 and 2006-2020. In terms of the aggregate network, Chililabombwe ranked 6th out of 7 cities in Copperbelt and 23rd out of 30 in Zambia as of 2020.

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

What about similarly populated cities?

• Kaiserslautern, Germany
• Lajeado, Brazil
• Xikou, China
• Phulbari, Bangladesh
• Changning, China
• Zheleznogorsk, Russia

While Kaiserslautern and Phulbari both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Chililabombwe built increasingly disconnected streets over time in new street additions. For the full street network, though, all three cities follow the same trend. Chililabombwe and Kaiserslautern have been growing further apart in their street-network character since 1975.
