Kogi State Population 2026

Kogi State had an official population of 3,278,487 in the 2006 National Population Commission census, making it one of Nigeria's significant populated states at the time. Applying the NBS average annual growth rate of 2.9% for the state, the population is estimated at 5,807,390 in 2026, representing a significant increase over the two decades since the census. The state capital Lokoja is the largest urban centre, with a 2026 estimated population of 380,000. Urban population accounts for approximately 28.0% of the total, while 72.0% of residents live in rural areas. With a land area of 29,833 km², the population density is approximately 195 people per square kilometre.

Kogi State has a young population, with approximately 44.5% of residents under 15 years of age and 19.5% in the 15-24 age bracket — together representing the youth bulge characteristic of Nigeria's demographic profile. Working-age adults (25-54) make up 28.8% of the population, while seniors aged 55-64 and 65 and above account for 4.5% and 2.7% respectively. The gender split is approximately 50.2% male and 49.8% female.

The population of Kogi State has grown steadily since the 2006 census, driven by high fertility rates, improved access to healthcare reducing infant mortality, and rural-to-urban migration. Nigeria's population growth rate of approximately 2.9% annually means that Kogi State's population doubles roughly every 24 years (Rule of 70). By 2030, the state is projected to reach 6,510,922 residents. The absence of an updated national census since 2006 means that all post-2006 figures are estimates based on demographic modelling by the National Bureau of Statistics and UN Population Division. Nigeria's long-awaited census, postponed multiple times, will provide updated official data when completed.
