Middle-income countries in numbers

6,064,768,028 people lived in Middle-income countries in mid-2023: 75.0% of the world's people. That is 3.6 times its 1950 population of 1.68 billion.

The UN's medium projection has it peaking in 2067 at 7.16 billion, then falling to 6.75 billion by 2100.

The medium projection has deaths passing births in 2069 and staying above them from then on.

The median age was 21.6 in 1950 and 31.1 in 2023; the projection has 45.0 in 2100. 8.8% of people were 65 or older in 2023, against 25.8% projected for 2100. The working-age population (15–64) is projected to peak in 2049 at 4.51 billion.

What Middle-income countries is

Middle-income countries 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

Middle-income 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 Middle-income countries

On the UN's projection, Middle-income countries will have the most working-age people it ever has in 2049: 4,510,420,000 people aged 15–64. In 2023 it had 4,014,940,000.

100 aged 15–64

38 children

13 aged 65+

aged 15–64 children under 15 aged 65 and over

How to read this: take 100 people of working age — the orange row — and the two rows under it are the children (teal) and the people of 65 and over (violet) who lived alongside them in 2023.

Fewer than 50 dependants live alongside every 100 people aged 15–64 in 10 years: 2026–2035.

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 Middle-income countries, and who leaves

In 2020–2025 Middle-income countries loses 4,191,137 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 685,334 a year more leaving than arriving.

one square = 100,000 people a year

020406080+

more arrive than leave more leave than arrive

How to read this: age runs left to right, babies to 100. A blue square above the line means arrivals outnumber departures at that age, an orange square below it means the opposite. The figures are the UN's projection for 2020–2025; nobody recorded migration by age before 2020.

Across the counted years, 1950 to 2023, its biggest single-year gain was 894,720 (1981); its biggest loss, 9,035,673 (2022).

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.

How migration works everywhere

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

Who has the babies in Middle-income countries

Of every 100 babies born in middle-income countries in 2023, 9 had a mother under 20, 77 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.
