The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Fungurume plotted against Lualaba and Democratic Republic of the Congo. The SNDi of new construction in Fungurume rose steadily, compared to Lualaba which followed a zig-zag trend with an overall increase and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Fungurume's incremental SNDi rose from 3.43 to 3.73 between 1991-2005 and 2006-2020.

What about similarly populated cities?

• Chimbote, Peru
• Heshan, China
• Xiangyin, China
• Vrindavan, India
• Rewari, India
• Masrakh, India

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