2049Sierra Leone in 2049
United Nations projections (medium variant) put the population of Sierra Leone at 12,805,142 in 2049. That would be 14.0% more than in 2039 (11,230,061).
Half of the population would be younger than 27.1 years, with 28.5% children under 15 and 5.4% aged 65 or older. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
