Kipushi 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 Kipushi plotted against Haut-Katanga and Democratic Republic of the Congo. The SNDi of new construction in Kipushi peaked in 1991-2005, compared to Haut-Katanga which peaked in 1976-1990 and Democratic Republic of the Congo which followed a zig-zag trend with an overall increase. Most recently, Kipushi's incremental SNDi fell from 3.0 to 2.18 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kipushi ranked 5th out of 17 cities in Haut-Katanga and 17th out of 186 in Democratic Republic of the Congo as of 2020.

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