According to data from the Central Statistics Agency (BPS) studied by the Mandiri Institute, the number of middleclass people in Indonesia will reach 46.7 million by 2025. This figure is 2.5% lower than in 2024, which was 47.9 million.

The Mandiri Institute also found that there are 10 provinces that will experience the largest decrease in the number of middleclass people in 2025.

The first place is occupied by South Sumatra with a significant decrease of 693,000 people by 2025.

Next is Banten with a decrease of 268,000 people and Central Java with a decrease of 161,000 people.

Here is the full list of 10 provinces with the largest decrease in the number of middleclass people in 2025:

South Sumatra: 693,000 people
Banten: 268,000 people
Central Java: 161,000 people
Lampung: 134,000 people
DKI Jakarta: 119,000 people
West Sulawesi: 76,000 people
North Sulawesi: 73,000 people
Aceh: 71,000 people
Central Sulawesi: 65,000 people
Jambi: 54,000 people

According to the Mandiri Institute, this decline shows that the pressure on the middle class is asymmetric and influenced by the economic conditions of the regions.

"Therefore, a different policy approach is needed, where areas that are still growing are focused on maintaining momentum, while areas that are declining are focused on improving the quality of work and strengthening purchasing power," wrote the Mandiri Institute on its official Instagram account on Friday (6/2/2026).

This division of economic classes follows the definition of the World Bank, based on per capita spending per month relative to the poverty line.

This means that the measure of class is not based on income, but on how many times a person's spending exceeds the poverty line. The details are:

Poor: < 1 times the poverty line
Vulnerable: 1-1.5 times the poverty line
Potential middle class (AMC): 1.5-3.5 times the poverty line
Middle class: 3.5-17 times the poverty line
Upper class: >17 times the poverty line.
