Sierra Leone’s population rose to 8.8 m people in 2025.

Neither way is good in itself. A larger population can mean more workers, more customers and a bigger tax base, and it can also mean more demand for schools, clinics, housing and food. A smaller one would bring its own strains. The latest figure is 8.8 million people for 2025, up from 8.6 million a year earlier, a rise of 2.1%. Since 2016 the series has climbed from a low of 7.2 million, so the current reading is the highest in its range.

Why it matters. Adding 0.18 million people in a year means more children to enrol in school, more young adults looking for work and more households to feed and house. For firms it widens the pool of workers and buyers. For the state it raises the number of people that roads, health services and classrooms must reach each year.
