Taiwan Population: 2024 Figure, Trends and Outlook

Taiwan’s population was about 23.4 million in the 2024 preliminary estimate. The exact figure depends on the measure and reference date: a household-registration count, a statistical estimate and a future projection are not interchangeable. This guide summarizes dated official figures, explains the recent decline and gives context on population density and the outlook.

Taiwan's Population Today

For a recent, year-labelled benchmark, Taiwan’s 2024 Statistical Yearbook reports a preliminary population estimate of about 23.4 million. Household-registration figures offer more precise counts for particular dates, so a total should always be read together with its date and method.

The Latest Population Figure

The 2024 preliminary estimate rounds to 23,400,000 people. The Statistical Yearbook is useful for a consistent annual overview, while the Ministry of the Interior’s household-registration releases report totals tied to specific month-ends. For example, the registered population was 23,404,138 at the end of September 2024.

These figures are close, but they do not describe precisely the same measurement or reference date. For a current population answer, give the number and its date together rather than presenting a dated estimate as a live count. The figures cited here do not establish a 2026 total; for the newest month-end count, check the latest household-registration release from Taiwan’s Ministry of the Interior.

The yearbook also gives a broad snapshot of the population’s age structure in 2024: about 2.742 million people were aged 0–14, 16.169 million were aged 15–64, and 4.489 million were aged 65 or older. These rounded figures show why a single total does not describe demographic change on its own. The age groups refer to the yearbook’s preliminary statistical estimate and should not be mixed with counts for another date.

Population Density in Taiwan

Taiwan’s 2024 statistical yearbook reports a population density of 646.5 people per square kilometer. Density is an average across the area covered by the statistic; it does not mean that residents are spread evenly. The figure helps describe the overall concentration of population but cannot show how crowded an individual city, neighborhood or rural area feels.

Why Taiwan's East Coast Is Basically Empty

For travel, study or relocation decisions, a national average is only a starting point. Local conditions depend on the specific place being considered, so use city- or district-level information when comparing areas. The national density figure is best used for broad context, not as a substitute for local population data.

Taiwan Population by Year and Recent Trends

The available dated figures show a small decline between the end of 2023 and September 2024. They are snapshots from different dates, not a complete year-by-year series, and should not be treated as if they were all annual averages.

Recent Population Counts by Reference Date

The Ministry of the Interior reported 23,420,442 registered residents at the end of December 2023 and 23,404,138 at the end of September 2024. That is 16,304 fewer people across the two reference dates, or roughly 0.07% of the December 2023 count. This calculation describes the change between those two snapshots only; it is not an annual growth rate. The dated releases from the Ministry of the Interior make the comparison clear, but the nine-month interval is not the same as a calendar-year change.

The preliminary 2024 estimate is a separate statistical figure, rounded in the yearbook. Small differences between it and a registration total can reflect the method and reference period, rather than a contradiction. Use one consistent series when making comparisons over time. To build a true Taiwan population-by-year comparison, compare the same type of annual measure for each year rather than combining month-end counts with yearly estimates.

Why Taiwan's Population Is Declining

The dated registration counts show that the total fell over this period. A population changes through births, deaths and movement into or out of the population being counted; the total declines when these changes produce more losses than additions. The figures above establish the direction between those dates, but do not by themselves identify how much each factor contributed.

Age structure is also important context. In January 2025, the Overseas Community Affairs Council reported that people aged 65 and older had reached more than 20 percent of the population, meeting the commonly used threshold for a super-aged society. That milestone describes the population’s age profile; it is not itself a count of how many people live in Taiwan. It also has a different reference date from the yearbook’s preliminary 2024 age-group figures, so the two should not be treated as simultaneous measurements.

An older age profile can help explain why population totals and age-group totals may move differently, but the sources cited here do not quantify the separate effects of births, deaths and migration on the change between December 2023 and September 2024. The safest conclusion from those counts is limited: the registered total was slightly lower at the later reference date, while the 2025 report indicates that the share of older residents had crossed an important demographic threshold.

How Taiwan's Population Is Measured

Population figures answer different questions depending on whether they count registered residents, estimate the population for a period or model possible future change. Checking the label and reference date helps prevent misleading comparisons.

Registration Counts, Estimates, and Projections

A household-registration count records people in Taiwan’s official registration system at a stated date. It is useful for dated administrative counts, such as the Ministry of the Interior’s month-end totals. It should not automatically be described as a census result or as the number of people physically present on that exact day.

A statistical estimate is prepared for a specified period using an official statistical method. The 2024 yearbook labels its population figure a preliminary estimate, which is why it is best reported as an estimate rather than as a registration count. Estimates are useful for consistent annual context, but their date and status matter: a preliminary estimate may not match a count taken at a particular month-end.

A projection is different from both: it models possible future population paths using assumptions about factors such as fertility, mortality and migration. A projection is not a prediction that one exact outcome must occur. When reading any figure, note its date, whether it is a count or estimate, and whether it describes an observed or projected population. For comparisons, keep the measure consistent across the years or scenarios being considered.

Taiwan's Population Outlook

Future totals depend on demographic developments, so projections should be read as scenarios based on stated assumptions. They provide context for planning, not a replacement for the latest dated count. A projected figure is most useful when its scenario and projection period are clear.

What Official Projections Suggest

Taiwan’s National Development Council prepares long-range population projections every two years, incorporating the latest fertility, mortality and migration conditions. Its projections provide a way to consider how the population could change under different assumptions. The National Development Council provides the projection material and explains its approach.

For a present-day answer, use a dated official count or estimate. For questions about future population size, consult the relevant projection scenario and its assumptions. The key takeaway is that Taiwan had about 23.4 million residents in the 2024 preliminary estimate, with recent dated counts showing a modest decline and an aging population.
