Kasongo 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 Kasongo plotted against Maniema and Democratic Republic of the Congo. The SNDi of new construction in Kasongo was at its lowest in 1976-1990, compared to Maniema 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, Kasongo's incremental SNDi rose from 6.51 to 12.73 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kasongo ranked 7th out of 9 cities in Maniema and 177th out of 186 in Democratic Republic of the Congo as of 2020.
