THA · 1950–2100 · in brief
Thailand in numbers
71,702,435 people lived in Thailand in mid-2023: 0.89% of the world's people, and the 20th-largest population of the 236 countries and areas the UN reports. That is 3.5 times its 1950 population of 20.4 million.
Its population peaked in 2022 at 71.7 million and has been falling since. The UN's medium projection has 45.6 million in 2100. The projection is uncertain: on 1 January 2100 the UN's 95% range runs from 24.0 million to 70.8 million.
Deaths have outnumbered births every year since 2022, and do so in every projected year to 2100.
The median age was 18.5 in 1950 and 40.7 in 2023; the projection has 52.9 in 2100. 14.7% of people were 65 or older in 2023, against 35.5% projected for 2100. The working-age population (15–64) peaked in 2018 at 50.9 million; in 2023 it was 50.3 million.
Among countries it ranks 20th in 2023, 31st in 2050 and 50th in 2100. It is overtaken by Tanzania in 2026, the United Kingdom in 2030 and South Africa in 2035.

Thailand, 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.
THA · ages 15–64
Who does the work in Thailand
Thailand had the most working-age people it is ever expected to have in 2018: 50,873,400 people aged 15–64, against 50,329,400 in 2023.
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 42 years: 1991–2032.

THA · arrivals minus departures
Who arrives in Thailand, and who leaves
In 2020–2025 Thailand gains 18,488 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 20,853 a year more arriving than leaving.
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.
In the years that were counted, 1950–2023, the most it gained in one year was 183,471 (1998) and the most it lost was 27,740 (1958).
In 2024, 3,179,399 people living in Thailand had been born in another country, 4 of every 100 people there, against fewer than 1 in 1990.

Years in good health in Thailand
In Thailand, WHO puts the healthy years a newborn could expect in 2021 at 65.8 (95% range 64.7–66.7), out of 75.3 in all. That leaves 9.5 years in less than full health, close to the world's 9.5.
68.1 in full health, 10.9 not: 79.0 years
63.5 in full health, 8.3 not: 71.8 years
a year in full health a year in less than full health
How to read this: each square is a year of life, each row ten years; filled squares are years in full health, rounded to whole years.
Women: 68.1 healthy years of 79.0. Men: 63.5 of 71.8. In 2019, before the pandemic, the healthy years were 67.1.

Nearly everyone has electricity at home (2024). 9.1 of every 100 do not use the internet (2024).
