Yako 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 Yako plotted against Nord and Burkina Faso. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Yako's incremental SNDi rose from 1.16 to 1.97 between 1991-2005 and 2006-2020. In terms of the aggregate network, Yako ranked 1st out of 2 cities in Nord and 3rd out of 19 in Burkina Faso as of 2020.

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