French Guiana: population and ages

In mid-1950 there were 23,400 people, so the population is now 13.6 times as large.

The UN projects 7,560 births and 1,550 deaths in 2026, 6,020 more births than deaths.

More people leave than move in: net migration in 2026 is projected at minus 770.

The median age is 24.9, which is 6.2 years below the world’s 31.1.

31% of the people are under 15 and 7.4% are 65 or older (world: 24% and 11%).

The UN projects that people aged 65 and over will outnumber children under 15 from 2094.

Women have 3.2 children on average at today’s rates (world: 2.2), against 4.9 in 1950.

Life expectancy at birth is 77.5 years, above the world’s 73.8. In 1950 it was 47.7.

For mid-2050 the UN projects 472,000 people, 48% more than now, with a median age of 28.6.

By the death rates of 2023, life expectancy at birth was 77.0 years. People who had reached 65 could expect 18.4 more years for women and 15.1 for men.

On 1 January 2026, there are 12.0 people aged 65 or more for every 100 aged 15 to 64. For 2050, the UN projects 20.0.

For 2100 the UN projects a population of 775,000, with a 95 percent prediction interval of 77,200 to 6.42 million.

Life expectancy at birth is a period measure. It sums up the death rates of one year and is not a forecast of how long the babies born that year will live.

In mid-2024, 131,000 international migrants lived here, 42.4% of the population.

In mid-2024, 4,490 people from here lived in other countries.
