South-Eastern Asia in numbers

The UN counts 690,117,184 people in South-Eastern Asia in mid-2023, and 8.5% of the world's people. That is 4.2 times its 1950 population of 165 million. It covers 11 countries and areas; the largest are Indonesia (40.7%), the Philippines (16.6%), Vietnam (14.5%), Thailand (10.4%) and Myanmar (7.8%).

The UN's medium projection has it peaking in 2054 at 776 million, then falling to 679 million by 2100.

The medium projection has deaths passing births in 2055 and staying above them from then on.

The median age was 19.6 in 1950 and 31.2 in 2023; the projection has 47.2 in 2100. 7.8% of people were 65 or older in 2023, against 27.4% projected for 2100. The working-age population (15–64) is projected to peak in 2043 at 512 million.

South-Eastern Asia, 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 South-Eastern Asia

On the UN's projection, South-Eastern Asia will have the most working-age people it ever has in 2043: 512,069,000 people aged 15–64. In 2023 it had 468,912,000.

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 33 years: 2012–2044.

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

How to read this: 1950 on the left, 2100 on the right; coloured in the years with fewer than 50 dependants per 100 working-age people, grey in the rest, hatched where that is a projection.

How every country compares

AGG · arrivals minus departures

Who arrives in South-Eastern Asia, and who leaves

In 2020–2025 South-Eastern Asia loses 84,002 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 25–29, at 21,096 a year more leaving than arriving.

one square = 2,000 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.

In the years that were counted, 1950–2023, the most it gained in one year was 644,469 (1997) and the most it lost was 557,210 (2003).

This is a group of countries, so its figure counts only moves across its own outer edge: someone moving from one country inside it to another does not appear.

Who has the babies in South-Eastern Asia

Of every 100 babies born in South-Eastern Asia in 2023, 8 had a mother under 20, 76 a mother aged 20 to 34 and 16 a mother aged 35 or older. In 1950 it was 13 under 20 and 18 aged 35 or older.
