Central Java (Indonesian: Jawa Tengah, Javanese: ꦗꦮꦶꦩꦢꦾ, romanized: Jawi Tengah) is a province of Indonesia, located in the middle of the island of Java. Its administrative capital is Semarang. It is bordered by West Java in the west, the Indian Ocean and the Special Region of Yogyakarta in the south, East Java in the east, and the Java Sea in the north. It has a total area of 33,750.37 km, with a population of 36,516,035 at the 2020 Census making it the third-most populous province in both Java and Indonesia after West Java and East Java. The official population estimate in mid-2024 was 37,892,280 (comprising 19,037,740 males and 18,854,540 females). The province also includes a number of offshore islands, including the island of Nusakambangan in the south (close to the border of West Java), and the Karimun Jawa Islands in the Java Sea.

Central Java is also a cultural concept that includes the Yogyakarta Special Region, in turn including the city of Yogyakarta; however, administratively that city and its surrounding regencies have formed a separate special region (equivalent to a province) since the country's independence, and is administered separately. Although known as the "heart" of Javanese culture, there are several other non-Javanese ethnic groups, such as the Sundanese on the border with West Java. Chinese Indonesians, Arab Indonesians, and Indian Indonesians are also scattered throughout the province.

East Java (Indonesian: Jawa Timur, Javanese: ꦙꦮꦶꦮꦺꦠꦤ꧀, romanized: Jawi Wétan, Madurese: Jhâbâ Tèmor) is a province of Indonesia located in the easternmost third of Java island. It has a land border only with the province of Central Java to the west; the Java Sea and the Indian Ocean border its northern and southern coasts, respectively, while the narrow Bali Strait to the east separates Java from Bali by around 2.29 kilometres (1.42 mi). Located in eastern Java, the province also includes the island of Madura (which is connected to Java by the longest bridge in Indonesia, the Suramadu Bridge), as well as the Kangean islands and other smaller island groups located further east (in the northern Bali Sea) and the Masalembu archipelago to the north. Its capital is Surabaya, the second largest city in Indonesia, a major industrial center and also a major business center. Banyuwangi is the largest regency in East Java and the largest on the island of Java.

The province covers a land area of 48,036.84 square kilometres (18,547.13 sq mi), and according to the 2010 Census, there were 37,476,757 people residing there, making it Indonesia's second-most-populous province; the 2020 Census showed an increase to 40,665,696 people, while the official estimate for mid 2024 was 41,914,499 (comprising 20,848,660 males and 20,965,880 females). Almost a quarter of the population lives inside the Greater Surabaya metropolitan area. East Java is inhabited by many different ethnic groups, such as the Javanese, Madurese and Chinese. Most of the people in East Java adhere to Islam, forming around 94% of the total population. Other religions are also practiced, such as Christianity, Buddhism and Confucianism which are mostly practised by Tionghoa people and immigrants from Eastern Indonesia and North Sumatra, and also Hinduism which are practised by the Tenggerese people in the Bromo Tengger Semeru National Park and the Balinese people inhabiting the easternmost part of the province bordering Bali as well as the dominant minority Indian Indonesians in Surabaya city.

Min is a broad group of Sinitic languages with about 75 million native speakers. These languages are spoken in China in a region centered on modern Fujian Province, stretching from Southern Zhejiang to Eastern Guangdong, as well as on Hainan Island and the neighbouring Leizhou Peninsula. Min varieties are also spoken in Taiwan, and by a large international diaspora, particularly in Southeast Asia. The name Min is shared with the Min River in Fujian, and is also the abbreviated name of Fujian Province. Min languages are not mutually intelligible with one another nor with other varieties of Chinese.

The most widely spoken variety of Min outside of China is Hokkien, a variety of Southern Min which has its origin in Southern Fujian. Amoy Hokkien is the prestige dialect of Hokkien in Fujian, while a majority of Taiwanese people speak a dialect called Taiwanese Hokkien or simply Taiwanese. The majority of Chinese Singaporeans, Chinese Malaysians, Chinese Filipinos, Chinese Indonesians, Chinese Thais, and Chinese Cambodians are of Southern Min-speaking background (particularly Hokkien and Teochew), although some of these communities are shifting to national or regional languages. Communities speaking Eastern Min, Pu-Xian Min, Haklau Min, Leizhou Min, and Hainanese can also be found in parts of the Chinese diaspora, such as in Malaysia, Singapore, and Indonesia.

West Kalimantan (Indonesian: Kalimantan Barat) is a province of Indonesia. It is one of five Indonesian provinces comprising Kalimantan, the Indonesian part of the island of Borneo. Its capital and largest city is Pontianak. It is bordered by East Kalimantan and Central Kalimantan to the east, the Malaysian state of Sarawak to the north, and the Bangka Belitung Islands to the west and the Java Sea to the south. The province has an area of 147,037 km, and had a population of 4,395,983 at the 2010 Census and 5,414,390 at the 2020 Census; the official estimate as at mid 2023 was 5,623,328 (comprising 2,887,209 males and 2,736,119 females), and was projected to rise to 5,695,500 at mid 2024. Ethnic groups include the Dayak, Malay, Chinese, Javanese, Bugis, and Madurese. The borders of West Kalimantan roughly trace the mountain ranges surrounding the vast watershed of the Kapuas River, which drains most of the province. The province shares land borders with Central Kalimantan to the southeast, East Kalimantan to the east, and the Malaysian state of Sarawak to the north.

West Kalimantan is nicknamed "The Province of a Thousand Rivers". The nickname references the geography of the province, which features hundreds of rivers of varying size, most of which are navigable. Several major rivers are still the main route for freight to the hinterland, despite road infrastructure now reaching most districts.

Most speak the Palembang language, which is mutually intelligible to both Indonesian and local Palembang Malay. Other ethnic groups include the Javanese, Sundanese, Minangkabau and Chinese. Most are concentrated in urban areas and are largely immigrants from other parts of Indonesia.

Discrimination against people of Chinese descent in Indonesia has been carried out since the time of the Dutch East India Company. Serious violence against Chinese people has occurred at irregular intervals since 1740, when the soldiers of the Dutch East India Company and other ethnic groups from Batavia killed up to 10,000 people of Chinese descent during the Chinezenmoord. The worst outbreaks took place in 1946-49 during the Indonesian National Revolution against Dutch rule. There were significant outbreaks in the early 1960s. Violence against Chinese also took place in 1965 after the failed coup attempt during anti-communist purges; the main target of the killings being Native Indonesian communists. In May 1998, many Chinese businesses were burned down and many Chinese girls and women were raped and murdered.
