Small Island Developing States (SIDS) in numbers

Small Island Developing States (SIDS) had 72,894,706 people in mid-2023, 0.90% of the world's people. That is 3.1 times its 1950 population of 23.4 million.

The UN's medium projection has it peaking in 2064 at 84.3 million, then falling to 78.2 million by 2100.

Births stay ahead of deaths until 2069; in the medium projection, deaths are ahead every year after it.

The median age was 19.9 in 1950 and 30.4 in 2023; the projection has 43.6 in 2100. 9.2% of people were 65 or older in 2023, against 23.6% projected for 2100. The working-age population (15–64) is projected to peak in 2052 at 53.8 million.

What Small Island Developing States (SIDS) is

Small Island Developing States (SIDS) is one of the UN's analytical groupings. This dataset carries the group's totals, not its membership, so its countries are not listed here.

AGG · 1950–2100 · every age, every year

Small Island Developing States (SIDS), 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 Small Island Developing States (SIDS)

On the UN's projection, Small Island Developing States (SIDS) will have the most working-age people it ever has in 2052: 53,824,300 people aged 15–64. In 2023 it had 48,132,100.

aged 15–64 children under 15 aged 65 and over

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.

At no point between 1950 and 2100 do fewer than 50 dependants live alongside every 100 people aged 15–64 here.

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

How to read this: the strip runs 1950 to 2100. Coloured years are the ones with under 50 dependants for every 100 people aged 15–64; grey years are the rest, and a hatched year has not happened yet.

How every country compares

AGG · arrivals minus departures

Who arrives in Small Island Developing States (SIDS), and who leaves

In 2020–2025 Small Island Developing States (SIDS) loses 81,219 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 25–29, at 16,591 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.

Its best and worst years between 1950 and 2023: a gain of 86,187 (2022), and a loss of 377,929 (1999).

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 Small Island Developing States (SIDS)

Of every 100 babies born in Small Island Developing States (SIDS) in 2023, 11 had a mother under 20, 72 a mother aged 20 to 34 and 17 a mother aged 35 or older. In 1950 it was 15 under 20 and 15 aged 35 or older.
