The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Niger, for both new street additions (left) and the aggregate street network (right).
Niger in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Niger rose steadily. To get a sense of how street development has changed in Niger, we can consider three of its most populous regions: Niamey, Maradi and Tahoua. Out of the three regions, Niamey and Maradi do not follow the same trend as the country. The level of street-network sprawl in new development in Niamey followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Maradi followed a zig-zag trend with an overall increase.
How do development practices in Niger fare in comparison to others in the world? Most recently in 2006-2020, street construction in Niger was the 18th-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 Niger has become more connected. Niger ranked 12th in 1975, 8th in 1976-1990, 13th in 1991-2005 and 18th in 2006-2020.
The largest city in Niger is Niamey, with a population of 1192400 people. Taking into account the entire (i.e. aggregate) street network in Niamey as of 2020, the overall level of street-network sprawl is 1.7, which is very well-connected. The level of street-network sprawl in new development in Niamey followed a zig-zag trend with an overall increase.
Niger in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Niger is Tillabéri with an SNDi of 6.37, which is very sprawly. Conversely, the most connected city is Gouré with an SNDi of 1.2, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Gouré, Tillabéri.
The level of street-network sprawl in the aggregate network in Niger rose steadily. To get a sense of how the aggregate street network has changed in Niger, we can consider three of its most populous regions: Niamey, Maradi and Tahoua. Out of the three regions, Tahoua does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Tahoua was at its lowest in 1976-1990.
