Less developed regions, excluding least developed countries in numbers

In mid-2023 there were 5,646,178,858 people in Less developed regions, excluding least developed countries, and 69.8% of the world's people. That is 3.8 times its 1950 population of 1.48 billion.

The UN's medium projection has it peaking in 2060 at 6.50 billion, then falling to 5.94 billion by 2100.

Births stay ahead of deaths until 2062; in the medium projection, deaths are ahead every year after it.

The median age was 21.2 in 1950 and 31.6 in 2023; the projection has 45.9 in 2100. 9.0% of people were 65 or older in 2023, against 26.8% projected for 2100. The working-age population (15–64) is projected to peak in 2046 at 4.15 billion.

AGG · 1950–2100 · every age, every year

Less developed regions, excluding least developed countries, 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 Less developed regions, excluding least developed countries

On the UN's projection, Less developed regions, excluding least developed countries will have the most working-age people it ever has in 2046: 4,152,470,000 people aged 15–64. In 2023 it had 3,769,760,000.

How to read this: one orange square for each of 100 people aged 15–64 in 2023. Beneath them, teal for the children living alongside those 100 and violet for the people aged 65 or older.

Fewer than 50 dependants live alongside every 100 people aged 15–64 in 15 years: 2023–2037.

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

How to read this: one stripe a year from 1950 to 2100. A stripe takes colour in a year when fewer than 50 dependants live alongside every 100 people of working age, and stays grey otherwise; hatching means the year is projected.

How every country compares

AGG · arrivals minus departures

Who arrives in Less developed regions, excluding least developed countries, and who leaves

In 2020–2025 Less developed regions, excluding least developed countries loses 1,227,040 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 40–44, at 193,404 a year more leaving than arriving.

one square = 20,000 people a year

020406080+

more arrive than leave more leave than arrive

How to read this: each column is one age, youngest on the left. Above the line, in blue, are the ages gaining people; below it, in orange, the ages losing them. This is the UN's projection for 2020–2025 — the record of migration by age does not go back beyond 2020.

Across the counted years, 1950 to 2023, its biggest single-year gain was 1,432,025 (1981); its biggest loss, 3,827,595 (2002).

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 Less developed regions, excluding least developed countries

Of every 100 babies born in less developed regions, excluding least developed countries in 2023, 8 had a mother under 20, 78 a mother aged 20 to 34 and 14 a mother aged 35 or older. In 1950 it was 13 under 20 and 18 aged 35 or older.
