This report first compares access levels to basic physical infrastructure in Nigeria with those in relevant income peers in Africa and globally, and analyses how these are likely to evolve to 2040 along the current development trajectory (referred to here as the Current Path). Moreover, it addresses the question of whether Nigeria’s access levels are in fact worse than what could be expected given its income level. Next, the report explores a series of interventions aimed at improving basic infrastructure in Nigeria over the next 23 years before comparing the benefits of those interventions for the economy and for human development. A scenario that combines the individual interventions representing an ‘integrated push’ for access to basic infrastructure will also be explored. Lastly, the report models an intervention that simulates a faster reduction in fertility rates – and hence slower population growth than is expected on the Current Path.
