Compare Indonesia with another country
Where it stands
In 2025 Indonesia has 285,721,236 people, which is 3.49% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 4th by population, behind United States and ahead of Pakistan.
Since 1960
In 1960 the figure was 88,296,070. Since then the population has grown 3.24×, an average of 1.82% a year upward. It doubled at some point along the way — the year it first reached 176,592,140 was 1988.
The projection keeps rising to the end of the data: 320,712,949 in 2050, 12.2% above 2025. The highest figure on this page is that last one, so no peak has been reached yet.
The ranking in 2050
In 2050 the projected rank is 6th, down 2 places from 4th. Rankings move when other countries grow faster or slower, not only when Indonesia changes.
People and land
Indonesia covers 1,892,555 km² of land, so 2025 density is 151 people per km² — 76th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 15,097 people.
The fertility rate was 2.12 births per woman in 2024, above replacement level but falling in most countries; life expectancy at birth was 71.3 years (2024); 24.2% of people were under 15 and 7.5% were 65 or older (2025); 59% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.
Its nearest neighbours in the ranking are United States just above, with 342 million (1.2× as many), and Pakistan just below, with 255 million (1.12× as many as Pakistan has).
