SIDS Atlantic, Indian Ocean and South China Sea (AIS) in numbers

SIDS Atlantic, Indian Ocean and South China Sea (AIS) had 11,473,550 people in mid-2023, 0.14% of the world's people. That is 4.4 times its 1950 population of 2.6 million.

The UN's medium projection has it peaking in 2069 at 14.0 million, then falling to 12.9 million by 2100.

The medium projection has deaths passing births in 2068 and staying above them from then on. The population still grows until 2069, because more people arrive than leave.

The median age was 20.1 in 1950 and 31.6 in 2023; the projection has 44.6 in 2100. 9.6% of people were 65 or older in 2023, against 26.3% projected for 2100. The working-age population (15–64) is projected to peak in 2049 at 8.8 million.

AGG · 1950–2100 · every age, every year

SIDS Atlantic, Indian Ocean and South China Sea (AIS), 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.

AGG · ages 15–64

Who does the work in SIDS Atlantic, Indian Ocean and South China Sea (AIS)

On the UN's projection, SIDS Atlantic, Indian Ocean and South China Sea (AIS) will have the most working-age people it ever has in 2049: 8,759,160 people aged 15–64. In 2023 it had 7,972,680.

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 34 years: 2003–2036.

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 SIDS Atlantic, Indian Ocean and South China Sea (AIS), and who leaves

In 2020–2025 SIDS Atlantic, Indian Ocean and South China Sea (AIS) gains 24,929 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 15–19, at 22,717 a year more arriving than leaving.

one square = 5,000 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 205,885 (2022) and the most it lost was 146,605 (2020).

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.

AGG · births by the mother's age · 1950–2100

Who has the babies in SIDS Atlantic, Indian Ocean and South China Sea (AIS)

Of every 100 babies born in SIDS Atlantic, Indian Ocean and South China Sea (AIS) in 2023, 10 had a mother under 20, 70 a mother aged 20 to 34 and 20 a mother aged 35 or older. In 1950 it was 11 under 20 and 18 aged 35 or older.
