Guinea population pyramid 2026
15,441,992 people in 2026 (projected). Guinea’s pyramid is broad and young, but men become noticeably scarcer than women from their forties, years before old-age mortality would usually cause it.

Guinea age distribution in 2026
Children under 15 account for 40.2% of the population, while 3.5% are aged 65 or older. The remaining 56.3% are in the conventional working-age range of 15–64. On these shares, the site classifies Guinea’s age structure as youthful; the guide to expansive population pyramids explains what that shape implies.
The total age dependency ratio is 77.6: about 78 people under 15 or 65+ for every 100 people aged 15–64 (71.4 children and 6.2 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Guinea’s population pyramid
Late, gradual fertility decline
Guinea’s fertility rose slightly from about 6.0 children per woman in 1950 to a peak of 6.5 around 1990 and has only recently fallen faster, to about 4.0 in 2026. Survival improved more steadily: life expectancy climbed from about 36 years in 1950 to 56 in 2010 and 61 in 2023, while infant mortality dropped from 177 per 1,000 births to about 65. With fertility high and more children surviving, the population became younger for decades, and the median age fell from 20.4 in 1950 to 16.4 in 2000. The 2026 pyramid has no distinct cohort bulges or notches: each band is simply smaller than the one below, the shape expected where death rates have fallen well ahead of birth rates, as in the second stage of the demographic transition.
Mortality remains high by international standards. Under-five mortality is about 90 per 1,000 births in 2026, and the gap in life expectancy between women and men is only about two and a half years (62.4 against 59.9), narrower than in most countries. The Ebola epidemic of 2014–16, which began in Guinea, caused severe disruption to health services, but it does not produce a visible gap in the five-year bands.
Missing men in mid-life
The striking irregularity is on the male side above age 35. Up to the early thirties men slightly outnumber women, as expected from about 104 boys born per 100 girls. From the forties the balance tips quickly: 92 men per 100 women at 40–44 and 82 at 50–54, a deficit that in most populations appears only past 60. The UN estimates net emigration of about 800,000 people between 2000 and 2023, more than in the previous fifty years combined, and migration of working-age men abroad is a plausible contributor, though the chart alone cannot establish the cause or how accurately absent men are recorded.
Slowing growth
Under the medium scenario Guinea grows from about 15.4 million in 2026 to 23.4 million by 2050 and 32 million in 2100, with growth slowing steadily as fertility approaches two. Its 2026 age structure is closest to those of Sudan, Ethiopia, Benin, Gambia and Cameroon. About 40% of residents are under 15, a share that can be compared internationally in the highest child population share ranking.
What to notice across the years
Distinctive cohorts and turning points
No five-year band under age 80 is more than 10% larger or smaller than both of its neighbours, so Guinea’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.
In the UN medium scenario births outnumber deaths in every year through 2100. Children under 15 outnumber people aged 65 and older in every pyramid year through 2100.
Births, deaths, and migration
A pyramid changes in only three ways: births add to the base, deaths remove people at every age, and migration adds or removes people mainly in young adulthood. In 2026, Guinea is projected to record 497,357 births (about 1,362 births a day) and 136,486 deaths, a natural increase of 360,871. Net migration adds −19,725 people, ranking #163 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 10,050,473 births, 3,026,556 deaths, and cumulative net migration of −796,490. Over that period the balance of births and deaths moved the total more than migration did. See how migration shapes a pyramid and birth rate versus fertility rate. The medium scenario assumes net migration of −684,326 between 2026 and 2050.

Women in Guinea are projected to live 2.5 years longer than men, which is why the female side of the pyramid widens relative to the other at older ages (see the life expectancy gap ranking). Infant mortality has fallen from 177 to 63.1 deaths per 1,000 live births since 1950, ranking #5 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 28.1 years sets the spacing between generations, and so how far apart echo cohorts sit in the pyramid.
Median age, fertility rate, and global ranks for Guinea
The median age of 18.5 years splits the population into two equal halves. A total fertility rate of 3.96 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 61.2 years.
These ranks compare all 237 countries and areas in this dataset using the same 2026 UN medium projection. Ranks use the stored source precision, so displayed rounding can make adjacent values look identical; small differences should not be overinterpreted.
| Indicator | 2026 value | Global rank | Ranking direction |
|---|---|---|---|
| Population | 15,441,992 | #75 | Largest first |
| Median age | 18.5 years | #214 | Oldest first |

| Population aged 65+ | 3.5% | #196 | Highest share first |
Largest age groups in Guinea
The five largest cohorts identify where the 2026 population is concentrated. They can reflect past birth patterns, survival, and migration; the chart alone does not establish which cause dominates.
| Rank | Age group | Population | Share of total | Male / female |
|---|---|---|---|---|
| 1 | 0–4 | 2,261,000 | 14.6% | 1.1M / 1.1M |
| 2 | 5–9 | 2,069,934 | 13.4% | 1M / 1M |

Sex ratio and the balance by age
In the 2026 projection, Guinea has 7,652,545 males and 7,789,448 females. That is 98.2 males per 100 females, ranking #120 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 49.6% of the population and females for 50.4%. There are 136,903 more females than males overall. Among people aged 65 and older, the ratio is 73.3 males per 100 females.
The overall balance can conceal large differences by age; how sex ratios change with age explains the usual pattern. The ratio reflects the male/female categories in the UN source and is not a measure of gender identity. Compare all profiles in the sex-ratio ranking.
At birth, 104.5 boys are projected to be born for every 100 girls in 2026, close to the biological norm of about 105 (compare the sex ratio at birth ranking). The ratio at birth sets the balance at the base of the pyramid; how it changes with age then depends on survival and migration.
How Guinea has changed since 1950
The population has increased from 3,013,177 in 1950 to 15,441,992 in 2026, a change of 412%. Over the same span, median age moved from 20.4 to 18.5 years.
The under-15 share changed from 38.0% to 40.2%, while the share aged 65 and older changed from 5.3% to 3.5%. These shifts show why total population growth and age-structure change need to be read separately.
How the population could change by 2050
Under the UN medium scenario, Guinea’s population is projected to grow by about 52%, reaching 23,404,584 in 2050. The median age changes from 18.5 to 24.2 years.
The 65+ share is projected to rise by 1.1 percentage points to 4.6%. At the same time, the under-15 share is projected at 30.8%. How UN projections work explains the assumptions behind these figures.
The population is still rising at the end of the UN medium projection in 2100, when it reaches 32,007,047. The page therefore does not assign a peak year beyond the available horizon.
