Republic of the Congo’s population rose to 6.5 m people in 2025.

Neither way is good in itself. Population has no good or bad direction because a larger number brings both a bigger workforce and market and more people to feed, school and house. The latest figure is 6.5 million in January 2025, up from 6.3 million a year earlier, a rise of 2.4%. Since 2016 the population has ranged from 5.2 million to 6.5 million, so the latest reading sits at the top of that range.

Why it matters. With 6.5 million people, every year of growth adds pupils to classrooms, patients to clinics and new job seekers to the labour market. Households feel it in housing and food demand. The state has to stretch schools, health services and infrastructure across a larger population. Firms see a growing pool of customers and workers.
