Indonesia population pyramid 2026
287,886,782 people in 2026 (projected). Indonesia’s pyramid has nearly vertical sides from birth to age 44, the result of birth numbers that stopped rising after fertility fell in the 1970s–90s.

Indonesia age distribution in 2026
Children under 15 account for 23.9% of the population, while 7.8% are aged 65 or older. The remaining 68.3% are in the conventional working-age range of 15–64. On these shares, the site classifies Indonesia’s age structure as transitional; the guide to population pyramid types explains what that shape implies.
The total age dependency ratio is 46.4: about 46 people under 15 or 65+ for every 100 people aged 15–64 (34.9 children and 11.4 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Indonesia’s population pyramid
Family planning and a flattened base
In 1975 Indonesia had a textbook expansive pyramid, with fertility of about five children per woman. The national family planning program, launched in 1970 and run through a dedicated agency (BKKBN) with village-level distribution of contraceptives, is widely credited with a large share of the decline that followed, alongside rising schooling and urbanization. Fertility fell to about 3.1 by 1990 and 2.5 by 2000. The Indonesia 2000 pyramid shows the result: the four bands under age 20 are almost the same width, because the number of women having children kept rising while each woman had fewer children, and the two effects roughly cancelled out.
A wide working-age column
That plateau in births has now moved upward. In 2026 every band from 0–4 to 40–44 holds between about 7.2% and 8.4% of the population, giving the pyramid unusually straight sides through the working ages; the widest band, 10–14, was born in 2012–16. Above 45 the pyramid narrows quickly, since people born before the mid-1970s belong to smaller cohorts that also lived through much higher mortality. With so many adults relative to children and older people, Indonesia’s age dependency ratio is near its lowest point, a period policymakers there widely call the bonus demografi. Whether it translates into faster economic growth depends on employment and productivity, which the pyramid cannot show.
Fertility is now close to replacement, about 2.1 in the UN estimates, so the base is no longer widening, but momentum from the large cohorts in their twenties and thirties keeps the population growing. The Indonesia vs Philippines comparison shows a neighbor that started its decline later and is now cutting its base more sharply.
Under the UN medium scenario Indonesia reaches about 321 million by 2050, near its projected peak, with a median age near 37 and an older population that roughly doubles its share.
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 Indonesia’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.
Births outnumber deaths in 2026; the medium scenario projects deaths to exceed births from 2060. People aged 65 and older are projected to outnumber children under 15 by 2065.
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, Indonesia is projected to record 4,419,970 births (about one birth every 7.1 seconds) and 2,247,438 deaths, a natural increase of 2,172,532. Net migration adds −39,472 people, ranking #107 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 115,088,514 births, 46,108,071 deaths, and cumulative net migration of −1,185,570. 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 −1,162,226 between 2026 and 2050.
Annual values 1950–2100; dashed lines after 2023 are the UN medium projection. The trend table below lists the values by decade.

Women in Indonesia are projected to live 4.4 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 181 to 15.6 deaths per 1,000 live births since 1950, ranking #75 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 29.1 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 Indonesia
The median age of 30.7 years splits the population into two equal halves. A total fertility rate of 2.08 births per woman is close to the replacement level of roughly 2.1, and life expectancy at birth is 71.6 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 | 287,886,782 | #4 | Largest first |
| Median age | 30.7 years | #130 | Oldest first |
| Fertility rate | 2.08 | #103 | Highest first |

| Life expectancy | 71.6 years | #165 | Highest first |
| Population aged 65+ | 7.8% | #136 | Highest share first |
Largest age groups in Indonesia
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 | 10–14 | 24,143,329 | 8.4% | 12.4M / 11.8M |
| 2 | 15–19 | 23,785,181 | 8.3% | 12.2M / 11.6M |
| 3 | 5–9 | 22,587,288 | 7.8% | 11.6M / 11M |
| 4 | 20–24 | 22,233,567 | 7.7% | 11.4M / 10.8M |
| 5 | 0–4 | 21,978,373 | 7.6% | 11.3M / 10.7M |
Sex ratio and the balance by age
In the 2026 projection, Indonesia has 144,610,243 males and 143,276,540 females. That is 100.9 males per 100 females, ranking #65 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 50.2% of the population and females for 49.8%. There are 1,333,703 more males than females overall. Among people aged 65 and older, the ratio is 76.9 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, 106.1 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 Indonesia has changed since 1950
The population has increased from 68,799,025 in 1950 to 287,886,782 in 2026, a change of 318%. Over the same span, median age moved from 17.8 to 30.7 years.
The under-15 share changed from 41.2% to 23.9%, while the share aged 65 and older changed from 1.7% to 7.8%. These shifts show why total population growth and age-structure change need to be read separately. See the Indonesia population pyramid in 1950 for the full starting shape.
How the population could change by 2050
Under the UN medium scenario, Indonesia’s population is projected to grow by about 11%, reaching 320,712,949 in 2050. The median age changes from 30.7 to 36.8 years.
The 65+ share is projected to rise by 7.3 percentage points to 15.1%. At the same time, the under-15 share is projected at 19.2%. The Indonesia population pyramid for 2050 shows the projected shape in detail. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 322,603,672 in 2058. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
