Guam population

On the UN's projection, Guam will have the most working-age people it ever has in 2075: 124,916 people aged 15–64. In 2023 it had 103,006.

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 4 years: 1950–1953.

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

In 2020–2025 Guam loses 417 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 79 a year more leaving than arriving.

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 340 (1981); its biggest loss, 3,212 (2016).

In 2024, 84,159 people living in Guam had been born in another country, 50 of every 100 people there, against 50 in 1990.

How migration works everywhere

Of every 100 babies born in Guam in 2023, 7 had a mother under 20, 78 a mother aged 20 to 34 and 15 a mother aged 35 or older. In 1950 it was 7 under 20 and 16 aged 35 or older.

The mother's age: under 20 20 to 34 35 or older projected

How to read this: one block a year, 100 squares in each, a square for every hundredth baby. The colour is the mother's age group, and the three numbers underneath are those groups in order, youngest first.

UNHCR publishes no refugees, asylum-seekers or displaced people in or from Guam at the end of 2025.

An empty row is not the same as a zero. These figures cover the people one agency works with, so a country it has no operation in has nothing to report here.

How the world's displacement is counted

Of every 100 people in Guam in 2025, 85 lived in a town or suburb and 15 in the countryside.

How to read this: everyone here, shrunk to 100 squares, with the colour saying whether that hundredth person lives in a city, a town or the countryside. Every country is measured by the same rule.

How the world's people live

Of every 100 adults in Guam in 2020, 2 never went to school and 40 finished upper secondary or went further.

The middle projection has its working-age people most numerous in 2060; those among them who finished upper secondary are most numerous later, in 2070.

How to read this: the row is the adults (25 and over) shrunk to 100 people, coloured by how far each went in school, least schooling on the left. The Wittgenstein Centre's count, 2020.

How far the world's people went in school

No place in Guam is big and dense enough to count as a city under the UN's rule — at least 50,000 people, living 1,500 or more to the square kilometre.
