Taiwan Major Cities: Population, Roles, and Key Differences

Taiwan’s major cities differ in population, administrative scale, and the roles they play in the island’s economy and culture. Taipei is the national capital, but it is not the most populous city jurisdiction. This guide explains how to interpret city population comparisons, then profiles the six special municipalities and several other important city centers. It also shows how to choose which cities to explore based on their distinct character.

How to Understand Taiwan’s Major Cities

A list of the biggest cities in Taiwan can look different depending on what is being counted. Administrative cities, continuous built-up urban areas, and metropolitan regions do not have identical boundaries. Knowing which measure a figure uses makes a population comparison much more meaningful.

City Population and Metropolitan Population Are Not the Same

A city-proper population counts residents within a city’s official administrative boundaries. A metropolitan or urban-area estimate may include connected communities that belong to neighboring jurisdictions. For example, people may move through the Taipei–New Taipei urban area as one connected region in daily life, even though Taipei City and New Taipei City have separate administrations.

Population totals also need a reference date. City governments publish household-registration figures at particular dates, while other estimates may use a different method or cover a broader area. A figure for one city at the end of 2025 cannot be fairly ranked against another city’s figure from 2021, or against an estimate for a whole metropolitan region.

Taiwan’s special municipalities cover substantial administrative areas. Their boundaries may include dense urban districts as well as suburban, rural, coastal, or mountainous territory. As a result, a municipality’s total population describes its whole jurisdiction, not just its central urban core. Likewise, the municipality’s total land area does not tell you how large or continuous its built-up area is.

The available official figures illustrate why dates and definitions matter. Taipei City’s statistics report a registered population of about 2.52 million at the end of 2021, while Taoyuan City reported 2,354,356 residents at the end of November 2025. Taichung’s 2025 statistical yearbook reports 2,868,465 people under household registration by the end of that year. These figures use different dates, so they should not be treated as one exact, same-date ranking. The Taipei City Statistics, Taoyuan City Government population data, and Taichung City statistical yearbook each identify their own reference information.

These examples provide a sense of scale, but they do not make a complete, same-date league table. In particular, the figures above should not be read as proof of the exact order among every major city. For a fair ranking, compare official city-jurisdiction totals from a single date and use the same population measure throughout. If a source instead counts an urban agglomeration or metropolitan region, treat it as a separate comparison.

For a quick overview, it is more useful to compare city roles than to combine figures from unlike dates and boundaries:

Taipei Is the Capital, but New Taipei City Is More Populous

Taipei is Taiwan’s capital and the seat of national institutions. New Taipei City, the separate municipality that surrounds Taipei across a broad area, is generally identified as the most populous city jurisdiction. In short, the answer depends on the question: Taipei is the capital; New Taipei City is the largest by city-jurisdiction population.

60 Second City: Taipei, Taiwan!

The two names can be confusing because the cities are closely linked by everyday travel, housing, and business. They are nevertheless distinct administrative entities, each with its own municipal government. The wider Greater Taipei region is a practical description of a connected urban area, not another name for Taipei City alone.

When comparing their populations, use figures for Taipei City and New Taipei City from the same reference date and the same statistical measure. Do not compare Taipei City’s registered population with an estimate covering Greater Taipei. Taipei’s official statistics, for example, give a registered population of about 2.52 million at the end of 2021; that dated city figure should not be mistaken for a current total or a metropolitan estimate.

Taiwan’s Six Special Municipalities

The six special municipalities are New Taipei City, Taichung, Kaohsiung, Taipei, Taoyuan, and Tainan. They are large administrative jurisdictions, but their urban form and regional functions differ. The profiles below focus on what each city is known for and how it fits into Taiwan’s wider city network.

New Taipei City

New Taipei City is a large special municipality that extends around Taipei. Its districts include dense residential neighborhoods and suburban communities, as well as coastal and less densely settled areas. It is therefore more varied than a single central business district or continuous urban core might suggest.

New Taipei has its own municipal administration, even though residents and visitors often move between it and Taipei as part of one connected urban region. This distinction matters when reading city lists, arranging services, or comparing population totals: a neighborhood near the capital may be in New Taipei rather than Taipei City. New Taipei’s importance comes from both its large residential base and its varied communities, not from being a uniform extension of the capital.

For readers comparing places to live or visit, the municipality’s range of districts is important: a central, built-up neighborhood and a coastal or more outlying community can have quite different surroundings. It is more accurate to think of New Taipei as a collection of connected local areas than as one single downtown.

Taichung

Taichung is a major urban center in central Taiwan and serves as an important point of reference for the region. Its municipal boundary includes multiple districts and a range of urban settings. For travelers, students, and businesses, its central location can make it a useful base for exploring or working in central Taiwan.

Taichung combines a substantial urban economy with cultural and visitor-facing activities. The city is associated with manufacturing as well as city-based arts, food, and public spaces, although the details vary across its districts. Its 2025 statistical yearbook reports 2,868,465 people under household registration at the end of the year. Because other city figures may use different dates or definitions, treat that as a dated official total rather than as a direct, same-date ranking against every other city.

Its regional role also helps explain why Taichung appears on many lists of Taiwan’s major cities: it is not simply a stop between northern and southern centers, but a substantial city in its own right. When comparing it with another municipality, keep the administrative total separate from any description of its central built-up districts.

Kaohsiung

Kaohsiung is a major city in southern Taiwan with a strong port identity. Its maritime setting and industrial history have helped shape its regional role, while its urban waterfront and cultural spaces contribute to a different feel from the northern capital region. It is an important choice for readers interested in southern Taiwan’s urban life and port-city character.

Kaohsiung’s municipal area is extensive, so the population and land area of the whole municipality should not be read as measurements of one continuous downtown. Urban districts, more outlying areas, and the port environment are part of the same jurisdiction but have different patterns of settlement and activity. This is why a city-proper total and a built-up-area estimate may describe different aspects of Kaohsiung.

The city’s port identity distinguishes its regional function from Taipei’s concentration of national institutions and from Tainan’s heritage profile. That makes Kaohsiung a useful point of comparison when thinking about how Taiwan’s major urban centers serve different parts of the island.

Taipei

Taipei is Taiwan’s political capital and a leading center for business, culture, education, and visitor services. National institutions and a concentration of commercial activity give it a central role that is distinct from its population rank. For many international visitors, Taipei is also the best-known starting point for understanding Taiwan’s urban culture.

Its close relationship with New Taipei City can make the boundary between the two seem less noticeable in everyday life, but the municipal distinction remains important. Taipei City’s registered population was about 2.52 million at the end of 2021, according to Taipei City statistics. That historical figure refers to Taipei City itself, not to the whole Greater Taipei region.

For population comparisons, Taipei’s national importance and its city-proper population answer different questions. Its capital status is not a claim that it is the largest municipality, and connected neighborhoods beyond its boundary remain part of neighboring jurisdictions.

Taoyuan

Taoyuan is a northern special municipality with an important role in transport, logistics, and industry. Its location between Taipei and other parts of northern Taiwan makes it a significant gateway and a place where residential, industrial, and transport functions meet. Its districts vary in density, so the city should not be understood as one evenly built-up area.

The city government reported a population of 2,354,356 at the end of November 2025, across 13 districts. The same government material gives a total area of about 1,221 square kilometers, which helps explain why the municipal jurisdiction includes varied landscapes and communities. These figures are dated administrative statistics, not a measure of the size of Taoyuan’s continuous urban area.

Taoyuan’s role is especially relevant to readers considering northern Taiwan as a wider region rather than focusing only on the capital. Its transport and logistics functions complement Taipei’s political and business role, while its administrative boundaries encompass a broader mix of communities than a single urban center.

Tainan

Tainan is a major city in southern Taiwan known for its historical and cultural profile. Its long-standing heritage gives it a character different from the newer growth centers and business districts found elsewhere on the island. The city’s historic sites, local traditions, and food culture contribute to its appeal for visitors and residents.

Tainan is best understood through that cultural identity as well as its role as a large southern municipality. A short visit focused on heritage may feel very different from a visit centered on contemporary business districts or port activity. The city’s reputation for history and food can guide an itinerary, but Tainan is also a living urban center with neighborhoods and daily services beyond its visitor highlights.

In a broad comparison, Tainan and Kaohsiung illustrate two distinct southern-city profiles: one is especially associated with heritage and cultural traditions, while the other has a stronger port-city identity. This is a role-based distinction rather than a ranking of either city’s overall importance.

Other Important City Centers

Not every important city in Taiwan is a special municipality. Hsinchu City, Keelung, and Chiayi City have smaller administrative footprints, but each serves a distinct regional purpose. Keep each city separate from its neighboring county or wider urban area when interpreting maps and population information.

Hsinchu City

Hsinchu City is a regional center in northern Taiwan and is closely associated with the island’s high-technology economy. The city name is sometimes used loosely when discussing the broader technology and commuter region, so it is useful to distinguish Hsinchu City from Hsinchu County and from the wider area around them.

Its significance is not only a matter of population size. Hsinchu is relevant to readers interested in technology, research, and the related business ecosystem. When a source refers to a science park or technology cluster, check whether it means a site within the city, a nearby part of the county, or a regional network. That distinction prevents a regional economic description from being mistaken for the city’s administrative boundary.

As a result, Hsinchu may be important in an economic or regional comparison even though it is not one of the six special municipalities. Treat the city name and the wider technology region as related but not interchangeable geographic labels.

Keelung

Keelung is a northern port city with a separate city administration. Its port identity and location make it closely connected to the wider Taipei–Keelung urban region, but Keelung is not part of Taipei City or New Taipei City. The neighboring cities may feel linked through daily movement and regional connections, while remaining distinct jurisdictions.

For a city comparison, count Keelung as its own city rather than folding its population into a broader northern urban region. Its port-city character also gives it a different profile from the capital’s government and business functions. This distinction is useful when planning a route or reading a Taiwan cities list: regional proximity does not make neighboring cities the same place.

Keelung’s regional connection to the capital area helps explain its place in a wider northern Taiwan picture, but it does not change the city’s administrative identity. A city list should name it separately from Taipei and New Taipei.

Chiayi City

Chiayi City is a smaller but regionally significant urban center in southwestern Taiwan. It is separate from Chiayi County, and the two names should not be treated as interchangeable. The city government describes an administrative area of about 60 square kilometers and a population of nearly 270,000; these are approximate figures from its published background information, not a same-date population comparison for all cities.

Chiayi can serve as a useful urban point of reference for the surrounding region. When considering it as a base for travel, distinguish the city itself from destinations in nearby counties. Attractions and landscapes associated with a broader region may be outside Chiayi City’s municipal boundaries. The Chiayi City Government provides basic information about the city’s area and history.

Its smaller size does not make it equivalent to a town or attraction: Chiayi City is an independent city jurisdiction with its own local role. Its profile is best understood regionally rather than by comparing it directly with the population scale of the six special municipalities.

Comparing Taiwan’s Major Cities by Role

Population can indicate the scale of a city, but it does not tell you whether the city is a political center, a port, a heritage destination, or a technology hub. For many readers, the more useful comparison is what a city offers and how it relates to the part of Taiwan they want to understand.

Which City Fits Your Interests?

Choose Taipei if your focus is national institutions, business, or a major urban culture center. New Taipei City is the relevant name when you mean the large, varied municipality around the capital rather than Taipei City itself. For a broader metropolitan experience, consider the two as neighboring but administratively separate cities.

Taichung is a strong point of reference for central Taiwan, while Tainan is especially notable for historical and cultural interests. Kaohsiung offers a southern port-city perspective. Taoyuan is associated with transport and logistics in the north, and Hsinchu is especially relevant to readers interested in technology and research. Keelung and Chiayi City provide smaller-scale regional perspectives with their own identities.

These distinctions can help narrow a city list to the places most relevant to a particular question. Someone comparing administrative population should focus on city jurisdictions and matching dates; someone exploring regional identity may find the city’s economic, cultural, or geographic role more useful. For travel planning, also distinguish a city from nearby destinations that lie outside its municipal boundary.

These are role-based suggestions, not a ranking of the best places to live or visit. A city’s importance depends on the question being asked: population, administrative scale, economic activity, cultural heritage, or regional access can all produce a different comparison. Understanding those differences gives a clearer picture of Taiwan’s major cities than a list of population totals alone.
