Nigeria in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Nigeria followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Nigeria, we can consider three of its most populous regions: Lagos, Oyo and Rivers. Out of the three regions, Rivers does not follow the same trend as the country. The level of street-network sprawl in new development in Rivers rose steadily.

The largest city in Nigeria is Lagos, with a population of 10762900 people. Taking into account the entire (i.e. aggregate) street network in Lagos as of 2020, the overall level of street-network sprawl is 4.9, which is very sprawly. The level of street-network sprawl in new development in Lagos followed a zig-zag trend with an overall increase.
