POPULATION OF INDONESIA: DEMOGRAPHICS, GROWTH, TRENDS, IMPACTS

POPULATION OF INDONESIA

Indonesia is the fourth most populous nation in the world after China, India and the United States. About 55 percent of the Indonesian population — roughly 150 million people — live on the island of Java, which is about the size of California and considered the most crowded island on earth

Population: total: 283,587,097 (2025 estimate); male: 141,778,977; female: 141,808,120. The population: of Indonesia in 2014 was estimated to be 253,609,643 and 237.6 million according to preliminary 2010 census figures. This marked an increase of about 35 million since 2000.

Population density: people square kilometer 152 in 2026 (compared to 3 per square kilometer in Mongolia, 38 per square kilometer in the United States, and 530 in South Korea); Population density: people square mile: 412 (compared to 5 per square mile in Mongolia, 95 per square mile in the United States, and 3,000 to 3,500 in Bangladesh) [Source: World Population Review]

The population density of Indonesia was 131 persons per square kilometer in 2009, compared with 33.8 per square kilometer in the United States. In Java, Madura, and Bali, population densities are more than 900 per square kilometer. Census authorities in 2007 estimated an average density of 118 people/ square kilometers (Departemen Kesehatan, 2008). The population density on Java and Bali (977 people per square kilometers) was much higher than on other islands (50 people per square kilometers).

Population Distribution on Indonesia

Major population concentrations are Java, which is considered one of the most densely populated places on earth. On other islands Sumatra contains some of the most significant clusters, particularly in the south near the Selat Sunda and along the northeastern coast near Medan. The cities of Makasar (Sulawesi), Banjarmasin (Kalimantan) are also heavily populated [Source: CIA World Factbook, 2025]

Population distribution based on data from Data from the 2020 Indonesian Census remained uneven across the archipelago. Java continued to be the most densely populated island, accounting for about 56.1 percent of the total population, followed by Sumatra. West Java recorded the largest population increase, adding more than five million people during the decade.

About half of Indonesia’s people live on Java and 60 percent live on Java and Bali, representing only 7 percent of the land area of Indonesia. Java is one of the most densely populated areas in the world, with more than 120 million people, or some 945 persons per square kilometer. By contrast, the most densely populated Outer Islands have 90 persons or fewer per square kilometer. Jakarta, on the western end of Java, is the largest city, with an estimated population of 11.4 million in mid-2001. Java has so many people that the population has already outstripped the availability of land and water and residents of the island are being encouraged to move to another island.

Migrations have played a part in population fluctuations and distributions. Increased permanent or seasonal migration to cities accompanied economic development during the 1980s and 1990s. There has also been significant migration between rural areas, with people leaving places such as South Sulawesi and densely populated areas of Java and Madura for more productive work or farming opportunities in Central Sumatra or East Kalimantan.” [Source: Clark E.

Population Growth in Indonesia

Population growth rate: 0.7 percent (2025 estimate). Population growth rate was 0.95 percent (124th in the world) and the annual growth rate was 1.1 percent in 2014. Birth rate: 14.55 births/1,000 population (2025 estimate). The Birth rate in 2014 was 17.04 births/1,000 population (108th in the world). Death rate: 6.82 deaths/1,000 population (2025 estimate). The death rate in 2014 was 6.34 deaths/1,000 population (156th in the world). Net migration rate: -0.7 migrant(s)/1,000 population (2025 estimate). The net migration rate in 2014 was -1.18 migrant(s)/1,000 population (154th in the world). [Source: CIA World Factbook, 2025 +]

Indonesia's population increased from 119,208,000 in 1971 to 147,500,000 in 1980 to 179,300,000 in 1990 and 203,456,000 in 2002 while the fertility rate declined from 4.6 to 3.3 per thousand women, the crude death rate fell by 2.3 percent per year, and infant mortality declined from 90.3 to 58 per thousand live births. [Source: Clark E. Cunningham, Countries and Their Cultures, Gale Group Inc., 2001]

About 3 million new Indonesians, most of them on Java, are added to the population every year in the 2000s. This occurred even though the birth rate declined from 2.4 percent in 1978 to 1.5 in 2006. Indonesia's population growth rate declined from 2.32 percent in the 1970s to 1.82 percent in the early 1990s. Population growth has decreased as a result of Indonesia’s proactive family planning efforts. [Source: Jane Sabes, World Education Encyclopedia, Gale Group Inc., 2001]

The annual growth rate changed slightly, from 1.3 percent in 2000 to an estimated 1.1 percent in 2009, with a birthrate estimated at 18.8 per 1,000 population. Life expectancy at birth for the total population stood at an estimated 70.8 years (versus 67.9 years in 2000), with males projected to live 68.3 years and females 73.4 years. Fertility rates for women, based on births per woman, decreased slightly, from 2.6 in 2000 to an estimated 2.3 in 2009, and the infant mortality rate improved from 40.9 deaths per 1,000 live births in 2000 to an estimated 29.9 deaths per 1,000 in 2009. The overall death rate was estimated in 2009 at 6.2 deaths per 1,000 of the population. One consequence of a low birth rate is an increasingly older population.

Demography of Indonesia

Age structure: 0-14 years: 23.8 percent (male 34,247,218/female 32,701,367); 15-64 yers: 68.3 percent (male 96,268,201/female 95,961,293); 65 years and over: 8 percent (2024 estimate) (male 10,284,628/female 12,099,758), Age structure in 2014: 0-14 years: 26.2 percent (male 33,854,520/female 32,648,568); 15-24 years: 17.1 percent (male 22,067,716/female 21,291,548);25-54 years: 42.3 percent (male 54,500,650/female 52,723,359); 55-64 years: 7.9 percent (male 9,257,637/female 10,780,724); 65 years and over: 6.4 percent (male 7,176,865/female 9,308,056).

Indonesia is a young nation. Population 14 and under: 24.2 percent (compared to 40 percent in Kenya, 19 percent in the United States and 13 percent in Japan). Population 65 and above: 20.7 percent (compared to 3 percent in Kenya, 17 percent in the United States and 28 percent in Japan). [Source: World Bank]

Median age: total: 31.8 years (2025 estimate); male: 30.8 years; female: 32.3 years. Median age in 2014: total: 29.2 years; male: 28.7 years; female: 29.8 years. Based on estimates for 2009, Indonesians aged nine or younger represent the largest age cohort, totaling some 44.9 million, or nearly 19 percent of the population. Data from the 2020 Indonesian Census indicated that 70.7 percent of the population is in the productive age group of 15 to 64 years. In terms of age structure, 23.3 percent of the population was aged 0 to 14, 70.7 percent fell within the working-age group, and 6 percent were aged 65 and above.

Dependency ratios: total dependency ratio: 46.1 (2025 estimate); youth dependency ratio: 34.1 (2025 estimate); elderly dependency ratio: 12 (2025 estimate); potential support ratio: 8.3 (2025 estimate). In 2014, the total dependency ratio was: 51 percent; youth dependency ratio: 43 percent; elderly dependency ratio: 8 percent; potential support ratio: 12.5. The dependency ratio is a demographic metric measuring the ratio of non-working-age dependents (children 0-14 and elderly 65+) to the working-age population (15-64). It highlights the economic burden on the productive workforce, with higher ratios indicating greater pressure to support dependents through taxes or social services.

Indonesia’s gender ratio is fairly balanced, and comparable to that of its regional neighbors Sex ratio: at birth: 1.05 male(s)/female; 0-14 years: 1.05 male(s)/female; 15-64 years: 1 male(s)/female; 65 years and over: 0.85 male(s)/female; total population: 1 male(s)/female (2024 estimate) ex ratio in 2014: at birth: 1.05 male(s)/female; 0-14 years: 1.04 male(s)/female; 15-24 years: 1.04 male(s)/female; 25-54 years: 1.03 male(s)/female; 55-64 years: 1 male(s)/female; 65 years and over: 0.78 male(s)/female; total population: 1 male(s)/female. The rate of 1.05 males born for every female born is the same as for Australia, Brunei, Papua New Guinea, the Philippines, and Timor-Leste. Malaysia’s gender ratio stood at 1.07:1 and Singapore’s at 1.08:1.

2020 Indonesian Census

The 2020 Indonesian Census (SP2020) recorded a total population of 270.2 million people, an increase of 32.56 million compared to 2010. The census showed an average annual population growth rate of 1.25 percent from 2010 to 2020, a slowdown from the 1.49 percent growth recorded in the previous decade. More than 91 percent of residents were recorded based on their Family Card (KK) registration.

Urbanization continued to rise, with a growing share of Indonesians living in urban areas. This trend reflected broader economic and social changes, including shifts toward industrial and service-based activities.

The census marked the first collaboration between Statistics Indonesia (BPS) and the Ministry of Home Affairs, combining digital population records with traditional field enumeration. Conducted during the COVID-19 pandemic, it used online data collection methods supplemented by field verification. Further analysis through the Long Form Census, completed in 2023, provided more detailed information on fertility, mortality, and migration. The 2020 census data now serves as the basis for Indonesia’s population projections through 2050.

2010 Indonesia Census

Indonesia’s population was officially recorded at 237,556,363 as of July 1, 2010, based on the nationwide census conducted that year. The figure exceeded earlier government projections of about 234.1 million, highlighting faster-than-expected growth. The results raised concerns about the effectiveness of the national family planning program, particularly in the years following the end of Suharto’s rule. Population growth averaged 1.49 percent annually from 2000 to 2010, essentially unchanged from the previous decade, suggesting that earlier gains in slowing growth had stalled. [Source: Jakarta Post, August 19 2010 |~|]

At that rate, projections indicated that Indonesia’s population could increase by another 15 million within five years, pushing the total beyond 250 million during the presidency of Susilo Bambang Yudhoyono. This rapid expansion raised questions about the country’s ability to provide sufficient food, education, and employment for its growing population.

Analysts warned that while a Malthusian-style crisis—where population growth outpaces food production—was not imminent, the scale of the challenge was significant and could be exacerbated by major disruptions such as natural disasters. Despite criticisms of his rule, Suharto was credited with promoting an effective family planning program during his three decades in power, which reduced population growth from 2.31 percent annually to 1.49 percent, helping to ease long-term demographic pressures.

Population Trends and Challenges in Indonesia

Family planning efforts in Indonesia largely stalled beginning in the late 1990s when democratic rule began, raising concerns that the country could miss out on the benefits of its large, youthful population. Officials warn that without renewed efforts, Indonesia risks losing its “demographic dividend,” in which a growing working-age population can drive economic growth. In 2014, the national statistics agency projected that the population could rise to 305 million by 2035. However, without improvements in education and employment opportunities, this growth could become a burden rather than an advantage for Southeast Asia’s largest economy. [Source: Kanupriya Kapoor, Reuters, January 30, 2014]

Government officials have stressed that the period leading up to 2030 presents a critical window, as the working-age population is expected to expand rapidly. They argue that the family planning program needs to be revitalized, noting that unless fertility rates decline further, the country may fail to capitalize on this demographic opportunity.

Indonesia has struggled to meet its fertility targets. The goal of reducing the rate to 2.1 children per woman by 2014 was not achieved, and the rate has remained around 2.4 for the past decade. This marks a slowdown compared to earlier decades, when a centralized family planning program significantly reduced fertility rates.

Experts attribute part of the slowdown to decentralization following the end of Suharto’s rule, which shifted responsibility for such programs to local governments. Participation has declined as family planning is sometimes viewed as a legacy of the previous regime.

Indonesia continues to face challenges linked to population distribution, particularly on the densely populated island of Java. While past transmigration policies sought to ease pressure by relocating people to less populated regions, uneven development persists. With more than 65 percent of the population expected to be of working age by 2035, economists warn that without better education and job creation, the potential economic gains could turn into social and economic strain.

Indonesia’s Population Surpassing the U.S. by 2043? And What That Means

If Indonesia’s population growth rate remains at 1.49 percent, it nation would overtake the U.S. as the world’s third-most-populous country by 2043, based on predictions by the U.S. Census Bureau and Bloomberg calculations. “Indonesia is seen by other countries as an opportunity because of its population,” Aris Ananta, who has published books on Indonesian demographics and is currently a senior research fellow at the Institute of Southeast Asian Studies in Singapore told Bloomberg . “It’s an asset. The government is shifting its responsibilities if it’s blaming population growth” for a failure to provide enough infrastructure or jobs, he said. [Source: Shamim Adam, Berni Moestafa and Novrida Manurung, Bloomberg, January 28, 2014 -]

Bloomberg reported:“While the rising supply of factory workers appeals to investors, it means the government has to direct more of its resources on education.Public spending on education as a percentage of government expenditure rose to about 17 percent in 2010 from 11.5 percent in 2001, according to the United Nations. Facing slower investment and one of the highest youth unemployment rates in the Asia-Pacific region, the government is concerned the demographic dividend that attracts companies seeking a young, cheap workforce will become an economic time bomb. As Indonesia’s growth slows, it isn’t generating enough quality jobs to keep up with the population, the International Labour Organization said. -

About 19.6 percent of Indonesian youths between the ages of 15 and 24 were jobless in 2012, compared with about 16 percent in the Philippines, according to the ILO. Unemployment, inflation and the so-called youth bulge, a phenomenon where a large share of the population is comprised of children and young adults, contributed to the Arab Spring protests that ousted leaders in Tunisia, Libya and Egypt in 2011. -

Impact of Indonesia’s Economy on Its Population

As more Indonesians leave plantation work for jobs in towns and cities, rising living costs have made it harder for families to support many children. Wahyu, 28, earns about 15,000 rupiah a day cutting flowers for shops in Jakarta. With such limited income, he mostly eats rice and dried fish and saves what little he can to one day open a motorcycle parts shop. He has only one child and says even that is difficult to support. “With only 15,000 rupiah a day, it’s hardly enough to raise one child,” he said, adding that life has become more challenging. [Source: Shamim Adam, Berni Moestafa and Novrida Manurung, Bloomberg, January 28, 2014]

Attitudes toward family size are also changing. A traditional saying in Indonesia holds that “many children bring many blessings,” but in urban areas like Jakarta, the reality has shifted toward higher costs and financial pressure. Todd Callahan of DKT International noted that the phrase is now often reinterpreted as “many children, many expenses.” Heru Purnomo, a 25-year-old courier worker in the capital, told Bloomberg he plans to have no more than two children. He pointed to increasing competition for jobs and the need for higher education as reasons to limit family size. “If you have too many children, you get left behind,” he said, reflecting concerns shared by many young urban workers.

Indonesia’s labor force was projected to grow by about 11.2 percent through 2020, roughly in line with overall population growth. With about half of the population under the age of 30, the country has attracted major international companies such as L'Oréal, which opened its largest factory in West Java in 2012 to serve Southeast Asian markets.

Spending patterns have also shifted. Government data showed that Indonesians were allocating a growing share of household budgets to non-food items, rising from 37.1 percent in 1999 to 52.3 percent in 2012. This reflects broader economic changes and increasing consumer demand beyond basic necessities.

Experts note that Indonesia’s large and youthful population offers significant economic potential, but the benefits depend on how well the country manages education, employment, and income growth. As Rajat Nag observed, a demographic dividend can be an advantage, but only if supported by effective policies and opportunities.

Migration To, From and Within Indonesia

Net migration rate: -0.7 migrant(s)/1,000 population (2025 estimate). The net migration rate in 2014 was -1.18 migrant(s)/1,000 population (154th in the world). By 2005, Indonesia’s net migration rate was zero. [Source: CIA World Factbook, 2025 +]

Historically, there had been considerable migration both from and to China. Following a decree banning foreigners from participating in retail trade in rural Indonesia, about 120,000 Chinese left the country in 1960–61. After the attempted coup of 1965 and the subsequent deterioration in relations with China, many more Chinese departed. Migration between the Netherlands and Indonesia was greatly reduced after independence; at that time, about 250,000 Dutch nationals—nearly all of whom later returned home—had been living in Indonesia. [Source: Worldmark Encyclopedia of Nations, Thomson Gale, 2007]

Resettlement of people from densely populated regions to the less populated outer islands became an official government policy. The 1979–84 National Economic Plan set a target of “transmigration” for 500,000 families from Java, Bali, and Madura to Sumatra, Kalimantan, Sulawesi, Maluku Province, and Irian Jaya. Participation was voluntary, and about 366,000 families—roughly 1.5 million people—were actually resettled. Since Java’s annual population increase exceeded two million, the costly transmigration program did little to ease congestion on the island, though it significantly contributed to the development of sparsely populated regions. Each family received two hectares (five acres) of land along with housing, food, seedlings, fertilizers, pesticides, and other supplies to help them become productive. Under the 1987–91 plan, an additional 338,433 families were resettled.

Indonesia granted first asylum to more than 145,000 Indochinese refugees between 1975 and 1993, including 121,708 from Vietnam. Of the Vietnamese asylum seekers, about 112,000 had been resettled in Western countries by 1996, while the remainder were expected to return home.

As a result of various conflicts, Indonesia had more than one million internally displaced persons (IDPs) who fled their homes to escape ethnic, religious, or political violence and military repression, particularly in Maluku, West Kalimantan, and East Timor. By 2004, the number of internally displaced persons stood at approximately 535,000.

In 2004, Indonesia had 169 refugees and 59 asylum seekers, with 16,390 individuals classified as persons of concern to the United Nations High Commissioner for Refugees (UNHCR), including about 16,000 from East Timor and Afghanistan. In the same year, more than 7,000 Indonesians applied for asylum in Malaysia, the United States, and Australia. Additionally, 15,181 Indonesians were refugees in Malaysia, and 7,626 were in Papua New Guinea.
