Comprehensive Analysis of Indonesia Demographic: Average Age, Birth Rate, Life Expectancy, and Future Outlook

Indonesia, with a population of approximately 280 million people, is the 4th most populous country in the world. This nation, home to diverse ethnic groups, cultures, and languages, has undergone rapid economic development and social transformation in recent years. This article provides a detailed analysis of Indonesia’s demographics, including average age, birth rate, life expectancy, and future projections. Through these indicators, we aim to clarify Indonesia’s current situation and its challenges going forward.

Indonesia’s Population Trends

Indonesia has the largest population in Southeast Asia, and its demographic trends significantly impact both domestic and international economies and societies.

Historical Population Growth:

Indonesia’s population has steadily grown over the past several decades:

• 1950: approx. 79.53 million

• 1990: approx. 182.47 million

• 2000: approx. 212.09 million

• 2010: approx. 237.71 million

• 2020: approx. 263.75 million

This data shows that Indonesia’s population has roughly tripled over the past 70 years.

Current Population:

As of 2025, Indonesia’s total population is estimated at around 280 million, making it the world’s fourth most populous country.

Future Projections:

According to the United Nations:

• 2030: approx. 290 million

• 2045: approx. 324 million

However, due to rapid population growth in countries like Nigeria and Pakistan, Indonesia’s global ranking is expected to drop from 4th to 6th place.

Changes in Age Structure:

• The percentage of the population aged 0–14: from 24.56% in 2020 to 19.61% in 2045 (projected)

• The percentage of those aged 65 and over: from 6.16% in 2020 to 14.61% in 2045 (projected)

These trends suggest Indonesia is heading toward an aging society.

Factors Behind Population Growth:

• High birth rate: Although declining, the birth rate remains relatively high.

• Advances in healthcare: Improved medical care has reduced infant mortality and extended life expectancy.

Future Challenges:

• Social security system development: Strengthening pension and healthcare systems to support the growing elderly population.

• Labor force shortages: A potential decline in the working-age population.

• Education and healthcare infrastructure: Expanding educational opportunities and providing medical services across all generations.

Indonesia’s demographic changes significantly affect not only its domestic policies but also the region’s overall development. Strategic measures are needed to ensure sustainable growth.

Indonesia’s Population Pyramid

A population pyramid visually displays the age and gender distribution of a country or region, with the population on the horizontal axis and age groups on the vertical axis, typically showing males on one side and females on the other.

Characteristics of Indonesia’s Population Pyramid:

• Large youth population: As of the 2020 census, 0–14 year-olds made up 23.33% of the total population.

• Dominant working-age population: 15–64 year-olds accounted for 70.72%, indicating a plentiful labor force.

• Elderly population: 65 and older comprised 5.95%.

Demographic Bonus Period:

A high proportion of working-age population is called a “demographic bonus,” which can drive significant economic growth. Indonesia is currently in this phase, and with appropriate policies and investments, sustainable economic development is achievable.

Future Outlook:

According to the UN, Indonesia’s population will continue to grow until 2030, but aging will become a growing concern, necessitating long-term social security and healthcare system development. Utilizing the large current workforce while preparing for future aging is crucial.

Indonesia’s Average Age

Indonesia’s median age has shifted along with its economic development:

• 2017: Median age was 30.2 years

• 2020: Increased to 31.1 years

• 2024: Estimated at 29.7 years

Indonesia’s average age remains younger compared to countries like Japan, China, and Thailand.

Demographic Bonus Period:

Currently, Indonesia’s working-age population (15–64) accounts for 67% of the total population, providing significant economic growth potential.

Future Outlook:

The working-age population is expected to peak around 2030, offering a window of opportunity for high growth. However, preparation for aging through robust social security and healthcare systems remains essential.

Indonesia’s Birth Rate

The Total Fertility Rate (TFR) — the average number of children a woman bears in her lifetime — is a key demographic indicator. Indonesia’s TFR has steadily declined over past decades:

TFR Trends:

• 1980: approx. 4.49

• 1990: approx. 3.10

• 2000: approx. 2.54

• 2010: approx. 2.45

• 2020: approx. 2.19

• 2021: approx. 2.18

Reasons for Historically High Birth Rates:

• Traditional family values: Emphasis on large families was deeply rooted.

• Agriculture-based economy: In rural areas, children were valued as labor.

• Limited access to education and healthcare: Lack of contraception knowledge and options contributed to high birth rates.

Reasons for Recent Decline:

• Government family planning: Starting in the 1970s, family planning programs promoted contraception and awareness.

• Improved education: Especially among women, leading to delayed marriage and childbearing.

• Urbanization and economic development: Rising living costs and limited housing space in cities discouraged large families.

Why Population Is Still Growing Despite Lower Birth Rates:

While the TFR has declined, the large cohort born during high-birth periods has now entered reproductive age, keeping the absolute number of births high. For example, the population reached approx. 263.75 million in 2020 and is projected to reach 324 million by 2045.

Thus, despite declining birth rates, Indonesia’s population continues to grow due to its demographic momentum. However, the country faces the challenge of preparing for an aging society and ensuring sustainable development.

Future Projections:

According to Indonesia’s National Development Planning Agency, TFR is expected to decline further, reaching 1.9 by 2045 — below the replacement level of 2.1 — raising concerns about future low birth rates and aging.

Regional Differences:

Significant regional variations exist. For example, Java’s average TFR is around 2.0, while provinces like East Nusa Tenggara, Papua, and Maluku still maintain relatively high birth rates. The government needs region-specific policies to address these gaps.

Government Initiatives:

Indonesia’s government launched the “Two Children Is Enough” family planning campaign in 1971, contributing to the declining TFR. The current goal is to maintain TFR around 2.1 to balance population control and aging concerns.

Indonesia’s Urbanization and Shifting Population Distribution

Indonesia has undergone rapid urbanization in recent decades, impacting economic development and social structures.

Urbanization Progress:

• In 1950, only about 15% of the population lived in urban areas.

• By 1990, this rose to 30%; by 2010, it reached 44%.

• Jakarta’s population density exceeded 14,400 people per square kilometer in 2010 and is expected to keep rising.

Changes in Population Distribution:

• Concentration in Java: About two-thirds of Indonesia’s urban population lives on Java, the country’s economic center.

• Aging in rural areas: Young people are migrating to cities, leaving rural areas with an aging population; 80% of farmers are over 45 years old, raising concerns about future agricultural labor shortages.

Urbanization Challenges:

• Strained infrastructure: Housing, transportation, and employment demands are rising. In Jakarta, traffic congestion causes an estimated $1.4 billion in annual economic losses.

• Socioeconomic duality: Modern lifestyles coexist with traditional “kampung” (village) societies in cities, leading to income gaps and social inequality.

Future Outlook:

The UN projects that by 2030, over 65% of Indonesians will live in urban areas. This will further accelerate rural population decline and aging. The government needs to invest in rural infrastructure and development to promote balanced growth between urban and rural areas.

Urbanization and shifting population distribution have widespread effects on Indonesia’s economy, society, and infrastructure, requiring strategic policies for sustainable development.

Life Expectancy in Indonesia

Life expectancy in Indonesia has been steadily increasing in recent years. According to the Central Bureau of Statistics, the life expectancy in 2021 was reported to be 73.5 years, with men averaging 60.67 years and women 73.55 years.

Life expectancy by gender:

• Men: 60.67 years

• Women: 73.55 years

Compared to Japan, these figures show a difference of about 20 years for men and about 15 years for women.

Trends in life expectancy:

Indonesia’s life expectancy has changed as follows:

• 2018: 70.34 years

• 2019: 70.52 years

• 2020: 68.81 years

• 2021: 67.57 years

Regional differences:

In the capital Jakarta, where healthcare and living standards are higher, life expectancy exceeds the national average at 73 years. Some estimates project it may reach 80 years by 2030.

Factors affecting life expectancy:

• Healthcare access: Shortages of medical facilities and professionals remain an issue in rural areas.

• Lifestyle habits: High smoking rates and diets rich in fats impact health.

• Sanitation: Some regions still require improvements in sanitation.

Future challenges:

Indonesia may face an aging society in the future, requiring strengthened social security and healthcare systems. Prevention of lifestyle diseases and promotion of health education are also important challenges.
Overall, while Indonesia’s life expectancy is improving, challenges such as regional disparities and lifestyle improvements remain.

Healthy Life Expectancy in Indonesia

Healthy life expectancy refers to the number of years people can live without health problems limiting daily activities. This differs from simple life expectancy as it focuses on quality of life.

Current status of healthy life expectancy in Indonesia:

According to WHO’s 2023 report, Indonesia’s healthy life expectancy is 62.8 years. Compared to the average life expectancy of 73.9 years that same year, there is a gap of approximately 11.1 years. This indicates that for about 11 years, people live with some health issues.

Factors affecting healthy life expectancy:

• Increase in lifestyle diseases: Economic development and urbanization have led to more non-communicable diseases such as diabetes and hypertension, which affect long-term health and shorten healthy life expectancy.

• High smoking rate: About 70% of Indonesian men over 20 are smokers, and approximately 400,000 people die each year from smoking-related diseases. Smoking increases the risk of cardiovascular and respiratory diseases, shortening healthy life expectancy.

• Healthcare access disparities: There are differences in healthcare quality and access between urban and rural areas. In rural areas, lack of timely diagnosis and treatment can negatively impact healthy life expectancy.

Government initiatives:

The Indonesian government has launched a free health check-up program to extend healthy life expectancy and prevent premature death. Every citizen can receive a free health check-up on their birthday, which includes blood pressure checks, cardiovascular and stroke risk assessments, vision tests, and mental health evaluations. The goal is to conduct examinations for 100 million people by 2025.

Indonesia’s healthy life expectancy is about 10 years shorter than its average life expectancy due to rising lifestyle diseases, high smoking rates, and healthcare access disparities. Through programs such as free health check-ups, the government aims to raise health awareness and promote preventive care. These initiatives are expected to help extend healthy life expectancy in the future.

Indonesia’s Demographic Bonus Period

Former President Joko Widodo (commonly known as Jokowi) stated, “We are currently in a demographic bonus period. To fully leverage this and achieve sustainable economic growth, improving education, infrastructure, and industrial policies is crucial.” He emphasized that “a demographic bonus does not automatically lead to economic growth; proper policies and investment are necessary.”

The demographic bonus period refers to a time when the proportion of the working-age population (15-64 years old) is high, and the proportion of dependents (under 14 and over 65) is low. This period can drive economic growth due to a large workforce and relatively lower social welfare burdens.

Relationship between the demographic bonus and economic growth:

• Increase in workforce: A growing working-age population activates production and economic activities.

• Higher savings rate: More workers lead to higher national savings and increased investment funds.

• Reduced social security burden: With fewer dependents, government spending on education, healthcare, and pensions decreases, allowing more investment in economic and infrastructure development.

Example of Japan:

Japan experienced a demographic bonus period from 1950 to 1990, achieving rapid economic growth. However, since the 1990s, Japan has entered a demographic onus period due to declining birthrates and aging, where the proportion of the working-age population decreases and dependents increase, potentially hindering economic growth.

Emerging countries:

Currently, countries like India, the Philippines, and Nigeria are in their demographic bonus periods, with expectations for future economic development. Their growing labor forces and active youth consumption are driving economic growth.

Cautionary note:

The demographic bonus does not automatically ensure economic growth. Without appropriate utilization of the workforce, improvements in education, infrastructure, and industrial policies, the expected benefits may not fully materialize.
Thus, the demographic bonus period represents a major opportunity for economic growth that requires suitable policies and investment.

Preparing for Population Decline and Aging in Indonesia

Indonesia is currently in its demographic bonus period, with the working-age population (15-64 years old) making up about 68% of the total population. However, it is projected to transition into an aging society in the future, making preparation for population decline and aging an important issue.

Current status and projections of aging:

• Increase in elderly population: According to the 2020 national census, the proportion of people aged 65 and older was 5.95%, slightly up from 5.04% in 2010. By 2045, this proportion is projected to reach 14.61%.

Government initiatives:

• Establishment of social security systems: Based on the National Social Security Law enacted in 2004, the Social Security Administration Agency (BPJS) was established, which includes “BPJS Health” for healthcare and “BPJS Employment” for work accident compensation, old-age benefits, pensions, and death benefits. This has built a comprehensive national social security system.

• Pension system reform: In July 2015, BPJS Employment implemented a comprehensive labor social security system that includes work accident compensation, death benefits, old-age benefits, unemployment benefits, and pension benefits. However, expanding membership and ensuring sustainability remain challenges.

• Elderly support strategy: The government has included a “National Strategy for the Elderly” (Stranas Kelanjutusiaan) in the 2020–2024 National Medium-Term Development Plan, promoting poverty reduction among the elderly and supporting healthy, active lifestyles.

Future challenges:

• Enhancing social security: As aging progresses, expanding pensions and medical services will be needed. In particular, promoting enrollment for informal workers and the self-employed is important.

• Establishing a care system: Currently, Indonesia lacks a public long-term care insurance system or national caregiver qualifications, and family care remains the norm. Establishing care systems and training care workers will be necessary.

• Securing the workforce: To address labor shortages due to population decline, strengthening education and skills training for the younger generation and promoting labor force participation by women and the elderly are crucial.

Indonesia is promoting policies to make use of its current demographic bonus and prepare for an aging society. However, further efforts are required to strengthen social security systems and develop care systems.
