List of largest cities in the context of "São Paulo"

A capital city, or just capital, is the municipality holding primary status in a country, state, province, department, or other subnational division, usually as its seat of government. A capital is typically a city that physically encompasses the government's offices and meeting places; the status as capital is often designated by law or a constitution. In some jurisdictions, including several countries, different branches of government are in different settlements, sometimes meaning there are multiple official capitals. In some cases, a distinction is made between the official (constitutional) capital and the seat of government.

English-language media often use the name of the capital metonymically to refer to the government sitting there. Thus, "London–Washington relations" is understood to mean diplomatic relations between Great Britain and the United States.

Tokyo, officially the Tokyo Metropolis, is the capital and most populous city in Japan. With a population of over 14 million in the city proper in 2023, it is one of the most populous urban areas in the world. The Greater Tokyo Area, which includes Tokyo and parts of six neighboring prefectures, is the most populous metropolitan area in the world, with 41 million residents as of 2024.

Lying at the head of Tokyo Bay, Tokyo is part of the Kantō region, on the central coast of Honshu, Japan's largest island. It is Japan's economic center and the seat of the Japanese government and the Emperor of Japan. The Tokyo Metropolitan Government administers Tokyo's central 23 special wards, which formerly made up Tokyo City; various commuter towns and suburbs in its western area; and two outlying island chains, the Tokyo Islands. Although most of the world recognizes Tokyo as a city, since 1943 its governing structure has been more akin to that of a prefecture, with an accompanying Governor and Assembly taking precedence over the smaller municipal governments that make up the metropolis. Special wards in Tokyo include Chiyoda, the site of the National Diet Building and the Tokyo Imperial Palace; Shinjuku, the city's administrative center; and Shibuya, a hub of commerce and business.

The New York metropolitan area, also called the Tri-State area and sometimes referred to as Greater New York or Metro New York, is the largest metropolitan economy in the world, with a gross metropolitan product of over US$2.6 trillion. It is also the largest metropolitan area in the world by urban landmass, encompassing 4,669.0 sq mi (12,093 km). Among the most populous metro areas in the world, New York is the largest metropolitan statistical area in the United States and the only one with more than 20 million residents, according to the 2020 U.S. Census.

The core of this vast area, the New York metropolitan statistical area, includes New York City and much of Downstate New York (Long Island as well as the mid- and lower Hudson Valley), northern and central New Jersey (including that state's eleven largest municipalities), and Southwestern Connecticut. The phrase Tri-State area is used to refer to the larger urbanized area of Downstate New York, northern New Jersey, and western Connecticut. The urban region's combined statistical area, the New York–Newark, NY–NJ–CT–PA combined statistical area, spans four states.

Cairo is the capital and largest city of Egypt and the Cairo Governorate, being home to more than 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world, and the Middle East. The Greater Cairo metropolitan area is one of the largest in the world by population with over 22 million people.

The area that would become Cairo was part of ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are near-by. Located near the Nile Delta, the predecessor settlement was Fustat following the Muslim conquest of Egypt in 641 next to an existing ancient Roman fortress, Babylon. Subsequently, Cairo was founded by the Fatimid dynasty in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries).

Mexico City is the capital and largest city of Mexico, as well as the most populous city in North America. It is one of the most important cultural and financial centers in the world, and is classified as an Alpha world city according to the Globalization and World Cities Research Network (GaWC) 2024 ranking. Mexico City is located in the Valley of Mexico within the high Mexican central plateau, at an altitude of 2,240 meters (7,350 ft). The city has 16 boroughs or demarcaciones territoriales, which are in turn divided into neighborhoods or colonias.

The 2020 population for the city proper was 9,209,944, with a land area of 1,495 square kilometers (577 sq mi), making it the second largest Spanish-speaking city proper in the world. According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21,804,515, which makes it the world's sixth-largest metropolitan area and the second-largest urban agglomeration in the Western Hemisphere (behind São Paulo, Brazil). Greater Mexico City has a GDP of $411 billion in 2011, which makes it one of the most productive urban areas in the world. The city was responsible for generating 15.8% of Mexico's GDP, and the metropolitan area accounted for about 22% of the country's GDP. If it were an independent country in 2013, Mexico City would be the fifth-largest economy in Latin America.

Java, the world's most populous island, is home to more than half of the country's population.

Indonesia operates as a presidential republic with an elected legislature and consists of 38 provinces, nine of which have special autonomous status. Jakarta, the largest city, is the world's second-most-populous urban area. Indonesia shares land borders with Papua New Guinea, Timor-Leste, and East Malaysia, as well as maritime borders with Singapore, Peninsular Malaysia, Vietnam, Thailand, the Philippines, Australia, Palau, and India. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support one of the world's highest levels of biodiversity.
