Mauritania in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Mauritania followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Mauritania, we can consider three of its most populous regions: Nouakchott, Dakhlet Nouadhibou and Hodh ech Chargui. Out of the three regions, Hodh ech Chargui does not follow the same trend as the country. The level of street-network sprawl in new development in Hodh ech Chargui was at its lowest in 1976-1990.
How do development practices in Mauritania fare in comparison to others in the world? Most recently in 2006-2020, street construction in Mauritania was the 20th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, street construction in Mauritania has become more connected. Mauritania ranked 2nd in 1975, 9th in 1976-1990, 8th in 1991-2005 and 20th in 2006-2020.
The largest city in Mauritania is Nouakchott, with a population of 1096300 people. Taking into account the entire (i.e. aggregate) street network in Nouakchott as of 2020, the overall level of street-network sprawl is 1.3, which is very well-connected. The level of street-network sprawl in new development in Nouakchott followed a zig-zag trend with an overall increase.
Mauritania in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Mauritania is Fassala with an SNDi of 3.25, which is moderately connected. Conversely, the most connected city is Zouérat with an SNDi of 1.26, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Zouérat, Fassala.
The level of street-network sprawl in the aggregate network in Mauritania rose steadily. To get a sense of how the aggregate street network has changed in Mauritania, we can consider three of its most populous regions: Nouakchott, Dakhlet Nouadhibou and Hodh ech Chargui. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Nouakchott followed a zig-zag trend with an overall increase. The level of street-network sprawl in the aggregate network in Dakhlet Nouadhibou followed a zig-zag trend with an overall decrease. The level of street-network sprawl in the aggregate network in Hodh ech Chargui was at its lowest in 1976-1990.
To date, Mauritania is the 20th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, the street network in Mauritania has become more connected. Mauritania ranked 2nd in 1975, 5th in 1976-1990, 8th in 1991-2005 and 20th in 2006-2020.
