Jamaari 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 Jamaari plotted against Bauchi and Nigeria. While Bauchi and Nigeria both followed a zig-zag trend with an overall increase, Jamaari's new street additions followed a zig-zag trend with an overall increase. Most recently, Jamaari's incremental SNDi rose from 2.11 to 2.94 between 1991-2005 and 2006-2020. In terms of the aggregate network, Jamaari ranked 5th out of 13 cities in Bauchi and 107th out of 422 in Nigeria as of 2020.
