Population and Demographics of Thailand
Population broadly stable in 2024 · median age 40 years
The fertility estimate of 1.2 should be read with the age profile, where 14.75% are children and 15.36% are older adults. That context matters for the outlook: the 2050 medium projection is 66.38 million, 7.4% lower than in 2024.
Population Over Time in Thailand
The 2000 to 2024 record shows Thailand moving from 63.008M people to 71.668M, a 13.7% increase. By 2050, the medium path reaches 66.383M, which would make the population smaller than in 2024. The chart connects dated reference points only and should not be read as an annual interpolated series.
Age Structure and Sex Balance
Broad age shares place Thailand in a maturing demographic position in 2024. The under-15 share is 14.75% and the 65-and-older share is 15.36%, with 69.89% aged 15 to 64. The youngest and oldest broad age groups are relatively close in size.
Population by broad age group
The 2024 World Bank sex-share indicator gives Thailand a female share of 51.3% and a male share of 48.7%. Females exceed males by 2.6 percentage points.
Female and male population share
Females made up 51.3% of the population in the World Bank's 2024 series, compared with 48.7% males.
What Is Shaping Population Change
Current momentum in Thailand combines -0.05% population change with fertility at 1.2, beside an age profile led by 69.89% in the 15-to-64 group.
The 2024 total in Thailand stands 13.7% above the 2000 reference, with a further -7.4% indicated under the 2050 medium scenario; births, deaths and migration are not apportioned here without a dedicated component series.

Thailand vs. World
Using one 2024 comparison table keeps the context consistent. Thailand's population change is lower than the global rate, fertility is below the global level, and its population is older than the world median-age profile.
| Indicator | Thailand | World | Year |
|---|---|---|---|
| Annual population change | -0.05% | +0.87% | 2024 |
| Total fertility rate | 1.2 | 2.25 | 2024 |
| Median age | 40 | 30.6 | 2024 |
All three comparison rows use 2024 values from the same harmonized country table. That table attributes its demographic series to UN World Population Prospects 2024, so no different-year values are mixed into this comparison.

Sources & methodology
This profile uses United Nations World Population Prospects 2024 as the primary framework for globally comparable population, age, fertility and projection data. The World Bank is the primary source for the female population share. Some country values were accessed through secondary retrieval interfaces that republish or organize UN data; those interfaces are identified below as secondary and are not treated as the original statistical publishers.
