The population of Indonesia was 270.20 million according to the 2020 national census, an increase from 237.64 million in 2010.[1] [2] The official estimate as at end 2023 was 280 million increasing at a rate of 1.17% per year.[3] Indonesia is the fourth most populous country in the world. Approximately 55% of Indonesia's population resides on Java, which is the most populous island in the world.

Despite a fairly effective family planning program that has been in place since 1967,[4] 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 projected to surpass the population of the United States if the recent population growth continues.[5]

Indonesia has a relatively young population compared to Western nations, though it is aging as the country's birth rate has slowed and its life expectancy has increased. The median age was 30.2 years in 2017.[6] Indonesia encompasses thousands of different ethnic groups, cultures, and hundreds of languages, some of which are related to each other. Since independence, Indonesian is the language of most written communication, education, government, and business. Many local ethnic languages are the first language of most Indonesians and are still important. Examples of local languages are Javanese, Sundanese, and Balinese.

Ethnic groups

See main article: article and Ethnic groups in Indonesia. Indonesia is a country of great ethnic diversity, with approximately 1,300 distinct indigenous ethnic groups living side by side across more than 17,000 islands.[14] [15] The majority of Indonesia's population is descended from Austronesian peoples who are concentrated in western and central Indonesia, which is part of the Asian continent. Another large group is the Melanesian peoples, who inhabit the eastern part of Indonesia (the Maluku Islands, Western New Guinea, and the East Nusa Tenggara) in Oceania.[16] [17]

The Javanese are the largest ethnic group, accounting for 40.2% of the population and are culturally, economically, and politically dominant. The Javanese are concentrated in Java, the most populous island, especially in the central and eastern parts, and also in significant numbers in most provinces due to extensive migration throughout the archipelago. The Sundanese are the next largest group (15.4%), followed by the Malays, Batak, Madurese, Betawi, Minangkabau, and Bugis. A sense of Indonesian nationalism is present along with strong ethnic and regional identities.[18]

Religions

See main article: article and Religion in Indonesia. Indonesia is the world's most populous Muslim-majority nation; based on civil registration data in 2023 from Ministry of Home Affairs, 87.06% of Indonesians are Muslims, 10.47% Christians (7.41% Protestants, 3.06% Roman Catholic), 1.68% Hindu, 0.71% Buddhists, 0.03% Confucians and 0.05% other faiths.[19] Most Indonesian Hindus are Balinese[20] and most Buddhists in modern-day Indonesia are Chinese.[21]

Languages

See main article: article and Languages of Indonesia.

Indonesian is the official and national language of Indonesia,[22] widely spoken by over 97% of the population. However, Indonesia is a highly multilingual country. According to Ethnologue, there are currently 737 regional languages spoken across the Indonesian archipelago. This extensive linguistic diversity accounts for about 10% of the world’s total languages, making Indonesia the second most linguistically diverse country in the world.[23] The majority of these languages belong to the Austronesian language family, which is prevalent in the western and central regions of Indonesia, including languages such as Acehnese, Batak, Sundanese, Balinese, Banjarese and Buginese. In contrast, the eastern regions, particularly Papua and the Maluku Islands, are home to over 270 Papuan languages, which are distinct from the Austronesian language family and represent a unique linguistic heritage.[24] The most widely spoken language as a mother tongue is Javanese, spoken by over 80 million speakers, mainly in central and east Java, but also on many other islands due to migration.
