Senegal in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Senegal followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Senegal, we can consider three of its most populous regions: Dakar, Diourbel and Thiès. Disconnectivity in the most populous cities in Senegal follow the same country trend.
How do development practices in Senegal fare in comparison to others in the world? Most recently in 2006-2020, street construction in Senegal was the 1st-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Senegal has become more disconnected. Senegal ranked 9th in 1975, 7th in 1976-1990, 2nd in 1991-2005 and 1st in 2006-2020.

The level of street-network sprawl in new development in Dakar followed a zig-zag trend with an overall increase.
Senegal in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Senegal is Kedougou with an SNDi of 3.22, which is moderately connected. Conversely, the most connected city is Fatick with an SNDi of 1.0, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Fatick, Kedougou.
