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 includes numerous ethnic, cultural and linguistic groups, 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.^{[citation needed]} Examples of local languages being Balinese, Gayo, and Taeʼ.

There are over 1,300 ethnic groups in Indonesia;^[19] 95% of those are of Native Indonesian ancestry. Javanese is the largest group with 100 million people (42%), followed by Sundanese, who number nearly 40 million (15%).

Indonesia is the world's most populous Muslim-majority nation; based on civil registration data in 2022 from Ministry of Home Affairs, 87.02% of Indonesians are Muslims, 10.49% Christians (7.43% Protestants, 3.06% Roman Catholic), 1.69% Hindu, 0.73% Buddhists, 0.03% Confucians and 0.04% other faiths.^[20] Most Indonesian Hindus are Balinese^[21] and most Buddhists in modern-day Indonesia are Chinese.^[22]

Indonesian is the official language, but there are many different languages native to Indonesia. According to Ethnologue, there are currently 737 living languages spoken in Indonesia,^[23] the most widely spoken being Javanese and Sundanese. In Western New Guinea, there are more than 270 indigenous languages in spoken form.^[24][25] Some Chinese varieties, most prominently Min Nan, are also spoken. The public use of Chinese, especially usage of Chinese characters, was dissuaded officially between 1966 and 1998.^[26]
