Guinea-Bissau in numbers

In mid-2023 there were 2,153,339 people in Guinea-Bissau: the 148th-largest population of the 236 countries and areas the UN reports, and 0.03% of the world's people. That is 4.0 times its 1950 population of 544 thousand.

In the UN's medium projection it is still growing in 2100, when it reaches 4.7 million. The projection is uncertain: on 1 January 2100 the UN's 95% range runs from 1.6 million to 15.3 million.

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

The median age was 21.4 in 1950 and 19.9 in 2023; the projection has 37.5 in 2100. 3.1% of people were 65 or older in 2023, against 15.4% projected for 2100. The working-age population (15–64) is still growing in 2100 in the medium projection.

By size it is the 148th country in 2023; the projection puts it 137th in 2050 and 129th in 2100. In the medium projection it overtakes Lesotho in 2031, Albania in 2033 and Lithuania in 2034. It is overtaken by Equatorial Guinea in 2080.

Guinea-Bissau, 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.

GNB · ages 15–64

Who does the work in Guinea-Bissau

In Guinea-Bissau the number of people aged 15–64 is still growing in 2100, the last year the UN projects. In 2023 there were 1,240,650 of them.

100 aged 15–64

How to read this: the orange squares are 100 people aged 15–64 in 2023, and the rows below are how many children (teal) and how many people aged 65 or older (violet) lived alongside them.

Fewer than 50 dependants live alongside every 100 people aged 15–64 in 11 years: 2064–2074.

fewer than 50 dependants per 100 the same, projected 50 or more

How to read this: one stripe a year from 1950 to 2100. A stripe takes colour in a year when fewer than 50 dependants live alongside every 100 people of working age, and stays grey otherwise; hatching means the year is projected.

How every country compares

GNB · arrivals minus departures

Who arrives in Guinea-Bissau, and who leaves

In 2020–2025 Guinea-Bissau loses 1,457 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 237 a year more leaving than arriving.

one square = 50 people a year

020406080+

more arrive than leave more leave than arrive

How to read this: left to right is age, from babies to 100. Blue squares above the line are ages at which more people arrive than leave; orange squares below it, ages at which more leave than arrive. These are the UN's projection for 2020–2025. There is no record of migration by age before 2020.

Across the counted years, 1950 to 2023, its biggest single-year gain was 33,922 (1977); its biggest loss, 23,936 (1964).

In 2024, 15,064 people living in Guinea-Bissau had been born in another country, fewer than 1 of every 100 people there, against 2 in 1990.

Years in good health in Guinea-Bissau

Of the 58.6 years a baby born in Guinea-Bissau in 2021 could expect, about 51.5 would be lived in full health (95% range 50.5–52.6). The years in less than full health come to 7.1, below the world's 9.5: shorter lives leave fewer years in which to be ill.

Displacement in Guinea-Bissau

How to read this: one square stands for 100 people, so the rows can be compared with one another. The last row is people from Guinea-Bissau living in another country, wherever they are.

In 2025, 398 people from Guinea-Bissau asked for asylum in another country. Of every 100 people from Guinea-Bissau whose claims were decided that year, 13 were given protection. Who asks for asylum, and who is given it
