Republic of the Congo in numbers

The Republic of the Congo had 6,182,885 people in mid-2023, the 113th-largest population of the 236 countries and areas the UN reports, and 0.08% of the world's people. That is 7.4 times its 1950 population of 835 thousand.

In the UN's medium projection it is still growing in 2100, when it reaches 20.0 million. The projection is uncertain: on 1 January 2100 the UN's 95% range runs from 9.2 million to 41.2 million.

Births outnumber deaths in every year from 1950 to 2100, estimates and projection alike.

The median age was 19.9 in 1950 and 19.3 in 2023; the projection has 34.2 in 2100. 2.9% of people were 65 or older in 2023, against 13.3% projected for 2100. The working-age population (15–64) is still growing in 2100 in the medium projection.

By size it is the 113th country in 2023; the projection puts it 95th in 2050 and 76th in 2100. In the medium projection it overtakes El Salvador in 2025, Bulgaria in 2027 and Serbia in 2027.

Republic of the Congo, every age in every year

Each column is a year and each row an age; the denser the ink in a cell, the more people. Everyone born in the same year climbs one 45° diagonal, so famines, baby booms and migration show up as streaks. Select a cell to follow its generation.

Who does the work in Republic of the Congo

In the Republic of the Congo the number of people aged 15–64 is still growing in 2100, the last year the UN projects. In 2023 there were 3,474,890 of them.

Who arrives in Republic of the Congo, and who leaves

In 2020–2025 the Republic of the Congo loses 2,538 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 670 a year more leaving than arriving.

How to read this: each column is one age, youngest on the left. Above the line, in blue, are the ages gaining people; below it, in orange, the ages losing them. This is the UN's projection for 2020–2025 — the record of migration by age does not go back beyond 2020.

In the years that were counted, 1950–2023, the most it gained in one year was 86,014 (2009) and the most it lost was 26,643 (2012).

In 2024, 385,589 people living in the Republic of the Congo had been born in another country, 6 of every 100 people there, against 5 in 1990.

Years in good health in Republic of the Congo

In the Republic of the Congo, WHO puts the healthy years a newborn could expect in 2021 at 54.8 (95% range 53.9–55.8), out of 63.2 in all. That leaves 8.4 years in less than full health, fewer than the world's 9.5, which mostly means lives are shorter here, with fewer years in which to be ill.

Displacement in Republic of the Congo

At the end of 2025, the Republic of the Congo was hosting 70,609 people who had crossed a border into it, about 11 of every 1,000 people living there.

How to read this: each square is 2,000 people, so the rows can be compared with one another. The last row is people from the Republic of the Congo living in another country, wherever they are.

In 2025, 537 people asked for asylum in the Republic of the Congo for the first time; 2,989 people from the Republic of the Congo asked for asylum in another country. Of every 100 people from the Republic of the Congo whose claims were decided that year, 21 were given protection. Who asks for asylum, and who is given it
