What is the population of Indonesia?

In 2017, Indonesia's population was projected to reach almost 262 million. Despite this large population size, it was dominated by the working-age population, resulting in a declining dependency ratio. The dependency ratio, which is the ratio of the non-working-age population to the working-age population, was 48.4 percent in 2016. This is significantly lower than the 86.6 percent recorded in 1971.

According to the National Development Planning Agency (Bappenas) report on Indonesia's Population Projection 2010-2035, Indonesia's population in 2020 would reach 271 million, an increase of 10 million from the previous year. By 2035, the population is projected to surpass 300 million.

The population growth rate from 2010-2035 is predicted to decline. Increased education levels, greater awareness of family planning, and changing lifestyles are contributing to slower population growth. The population growth rate was 1.38 percent during 2010-2015, decreasing to 1.19 percent during 2015-2020. It is further projected to decline to only 0.62 percent during 2030-2035, as Indonesia reaches the peak of its demographic bonus.
