Population of Indonesia

Let's talk about the population of Indonesia.

From 1960 to 2022, Indonesia's population surged from 87.75 million to 275.50 million, marking a remarkable 214.0% growth over 62 years. The most substantial annual increase occurred in 1967, reaching 2.76%, while the smallest uptick was observed in 2022 at 0.64%.

During the same timeframe, the global population soared by 162.2%. Indonesia's average age experienced a rise of 3.63 years, advancing from 27.47 in 2012 to 31.10 in 2021 (median value).

Approximately 58% of the population resides in larger cities, with urbanization expanding at a rate of 1.8% annually.

The population of Indonesia recorded a 0.74% growth from 2022, reaching 277,534,122 in 2023. In the preceding year, 2022, the population stood at 275,501,339, indicating a 0.64% increase from 2021.

Indonesia has a population density of 153 people per square kilometer (397 people per square mile). The population of Indonesia is growing at a rate of 0.6-0.8% per year. According to a recent survey conducted by the Central Statistics Agency (BPS), the population growth rate is projected to decrease from 0,6% in 2022 to 0.4% in 2045. By 2045, it is anticipated that Indonesia's population will reach 324 million.

Religious distribution in Indonesia is as follows:

• Islam: 87.02%
• Christianity: 10.49%
• Hinduism: 1.69%
• Buddhism: 0.73%
• Folk/Other: 0.04%
• Confucianism: 0.03%

Islam holds the predominant position in Indonesia as the largest religion. Sunni Muslims constitute approximately 99% of the Muslim population, with Shia Muslims making up around 1%, particularly concentrated in Jakarta, along with a presence of about 400,000 Ahmadi Muslims. Indonesia stands as the most populous Muslim-majority nation.

Concerning jurisprudential affiliations, demographic statistics indicate that 99% of Indonesian Muslims primarily adhere to the Shafi'i school. However, when surveyed, 56% express not adhering to any specific school. The spectrum of Islamic thought in Indonesia is broadly divided into "modernism," which aligns with orthodox theology while embracing contemporary education, and "traditionalism," which tends to follow interpretations from local religious leaders and educators at Islamic boarding schools (pesantren). Additionally, a syncretic form of Islam known as kebatinan has historically played a significant role.

The spread of Islam in Indonesia is attributed to various factors, including merchant activities by Arab Muslim traders, adoption by local rulers, and the influence of Sufism since the 13th century. During the late colonial era, Islam served as a rallying point against colonialism. According to a 2023 Pew Research Center report, 93% of the adult Indonesian population identifies as Muslim. Despite the overwhelming Muslim majority, Indonesia is constitutionally a secular state that officially recognizes six formal religions.

Hinduism holds the position of the third-largest religion in Indonesia and is recognized as one of the six official religions in the country. It was the predominant faith in Indonesia before the arrival of Islam. The introduction of Hinduism to Indonesia dates back to the 1st century, brought by Indian traders, sailors, scholars, and priests. A syncretic blend emerged, fusing pre-existing Javanese folk religion, culture, and Hindu ideas, which, from the 6th century, also incorporated Buddhist concepts, evolving into the unique Indonesian version of Hinduism. This synthesis continued to develop during the Srivijaya and Majapahit empires.

Around 1400 CE, the introduction of Islam by coast-based Muslim traders led to a decline of Hinduism, previously the dominant religion in the region, on many Indonesian islands. Today, Hinduism is the fourth-largest religion globally in Indonesia, following India, Nepal, and Bangladesh. Despite being a minority religion, Hindu culture has significantly influenced the lifestyle and daily practices in Indonesia. Outside of Bali, where Hinduism is prevalent, some adherents of traditional indigenous religions identify as Hindus to gain official recognition.

Christianity holds the position of the second-largest religion in Indonesia, following Islam. Indonesia boasts the second-largest Christian population in Southeast Asia, surpassed only by the Philippines. Moreover, it has the largest Protestant population in Southeast Asia and the third-largest Christian population in Asia, trailing behind the Philippines and China but surpassing India. Indonesia also ranks as the second-largest Christian population in the Muslim world, after Nigeria and ahead of Egypt.

With a Christian population of 29.1 million, several provinces in Indonesia have a Christian majority. The term "Kristen" in Indonesia specifically denotes Protestantism, while Catholicism is referred to as "Katolik."

In recent times, there has been notable growth and expansion of Christianity, particularly among the Chinese minority in Indonesia.

The Chinese community constitutes the most prominent ethnic minority of foreign origin in Indonesia, officially acknowledged to be around 2.8 million, although other estimates range from 2 to 4 million. The migration of Chinese individuals to Indonesia commenced in the 16th century, experiencing notable waves in the 19th and 20th centuries. Predominantly, they are concentrated in areas referred to as "pecinan" (chinatowns), notably in urban Java, including Jakarta, Surabaya, Tangerang, as well as in North Sumatra, Riau, Riau Islands, Bangka-Belitung Islands, and West Kalimantan.

Over time, the Chinese community has coexisted harmoniously with local ethnic groups such as the Betawi, Malay, Javanese, and Sundanese. In certain cities across Indonesia, significant Chinese populations have preserved their cultural heritage ties to China. This community is dispersed throughout the Indonesian archipelago, with substantial numbers residing in Palembang, Jakarta, Surabaya, and various other coastal cities.
