2020 Indonesian census in the context of "East Java"

Indonesia is a highly diverse country, both ethnically and linguistically. The country's population reached 270.20 million according to the 2020 national census, up from 237.64 million in 2010. As of mid-2025, the official estimate stood at 284.44 million, reflecting an annual growth rate of 1.11%. It remains the fourth most populous country in the world. Java, excluding Madura is home to approximately 54.4% of the national population, making it the most densely populated island globally.

Despite a fairly effective family planning program that has been in place since 1967, Indonesia's average population growth per year was over 1.1% for the decade ending in 2020, nearly having 13% population growth for that decade. At this rate, Indonesia's population is no longer projected to surpass the population of the United States (whose population is increasing at a faster rate), and it is itself projected by the United Nations (UN) to be overtaken in population by Nigeria and by Pakistan by 2040. Indonesia has a relatively young population compared to many Western countries, although it is gradually aging due to declining birth rates and rising life expectancy. As of 2017, the median age stood at 30.2 years.

The Bangka Belitung Islands (Indonesian: Kepulauan Bangka Belitung) is a province of Indonesia. Situated off the southeastern coast of Sumatra, the province comprises two main land masses — the islands of Bangka and Belitung — and numerous smaller islands. Bangka Belitung is bordered by the Bangka Strait to the west, the Natuna Sea to the north, the Java Sea is to the south and the Karimata Strait to the east; the two principal islands are separated by the Gaspar Strait, within which lie lesser islands such as Lepar, Pongok (or Liak) and Mendanau.

The province's capital and largest city is Pangkalpinang. The province shares maritime borders with South Sumatra to the west, Riau Islands to the north, Banten, the Special Capital Region of Jakarta, West Java, and Central Java to the south, and West Kalimantan to the east. Bangka Belitung covers a land area of 16,690.13 km (6,444.10 sq mi) and had a population of 1,455,678 according to the 2020 census; the official estimate as at mid 2024 was 1,531,530 (comprising 786,010 males and 745,520 females).

Banten (Sundanese: ᮘᮔ᮪ᮒᮨᮔ᮪, romanized: banten, Pegon: بنتن) is the westernmost province on the island of Java, Indonesia. Its capital city is Serang and its largest city is Tangerang. The province borders West Java and the Special Capital Region of Jakarta on the east, the Java Sea on the north, the Indian Ocean on the south, and the Sunda Strait (which separates Java from the neighbouring island of Sumatra) on the west and shares a maritime border with Lampung to the west. The province covers an area of 9,352.77 km (3,611.12 sq mi). It had a population of over 11.9 million in the 2020 census, up from about 10.6 million in 2010. The estimated mid-2024 population was 12,431,390, still increasing by about 106,000 people per year. Formerly part of the province of West Java, Banten was split off to become a separate province on 17 October 2000.

The northern half (particularly the eastern areas near Jakarta and the Java Sea coast) has recently experienced rapid rises in population and urbanization, and the southern half (especially the region facing the Indian Ocean) has a more traditional character but an equally fast-rising population.

Jayapura (formerly Hollandia) is the capital and largest city of the Indonesian province of Papua. It is situated on the northern coast of New Guinea island and covers an area of 940.0 km (362.9 sq mi). The city borders the Pacific Ocean and Yos Sudarso Bay to the north, the country of Papua New Guinea to the east, Keerom Regency to the south, and Jayapura Regency to the west.

With a population of 398,478 according to the 2020 census, Jayapura is the most populous city in the entire island of New Guinea, surpassing Port Moresby, the national capital and largest city of Papua New Guinea. During the 2010-2020 decade it was also the fastest-growing city in Indonesia, with the population increasing by 55.23% between 2010 and 2020. The official estimate as at mid 2023 was 414,862 (comprising 220,024 males and 194,838 females).

This is a list of all the 95 cities (with regency-level status) in Indonesia, ranked by population. It excludes urban-characterized settlements such as regency seats, which does not have city status. Indonesia has 93 cities classified as kota (city), one provincial-level capital city (Nusantara), and one provincial-level special city (the Special Capital Region of Jakarta). Population figures are taken from the 2020 census and the more recent official estimates as at mid 2024, all by Statistics Indonesia (BPS).

Jakarta is the largest city and the only megacity in Indonesia, with a population of 10.70 million. As a primate city, Jakarta is nearly four times larger than the second largest city Surabaya. Jakarta, along with Capital City of Nusantara, are unique compared to other cities in Indonesia, since they are technically provinces with a city management. Jakarta is subdivided into five administrative cities and an administrative regency, which are not self-governed (without municipal council nor government budget). Each of Jakarta's five satellite cities also have passed the one million mark in population, with the largest one being Bekasi, while the others are Depok, Tangerang, South Tangerang and Bogor.

West Sumatra (Indonesian: Sumatera Barat) is a province of Indonesia. It is on the west coast of the island of Sumatra and includes the Mentawai Islands off that coast. West Sumatra borders the Indian Ocean to the west, as well as the provinces of North Sumatra to the north, Riau to the northeast, Jambi to the southeast, and Bengkulu to the south. The province has an area of 42,119.54 km (16,262.45 sq mi), or about the same size as Switzerland or Penza Oblast, with a population of 5,534,472 at the 2020 census. The official estimate at mid 2024 was 5,836,160 (comprising 2,940,270 males and 2,895,880 females). The province is subdivided into twelve regencies and seven cities. It has relatively more cities than other provinces outside Java, although several of them are relatively low in population compared with cities elsewhere in Indonesia. Padang is the province's capital and largest city.

West Sumatra is home to the Minangkabau people, although the traditional Minangkabau region is actually wider than the province's boundaries, covering up to the western coast of North Sumatra, the southwestern coast of Aceh, the western region of Riau, the western region of Jambi, the northern region of Bengkulu, and Negeri Sembilan in Malaysia. Another native ethnic group is the Mentawai people, who inhabit the western islands of the same name. Islam is a predominant religion in the province, with about 97.4% of the total population.
