According to data from the Central Statistics Agency (BPS) studied by the Mandiri Institute, the number of middle-class people in Indonesia will reach 46.7 million by 2025. This figure is 2.5% lower than in 2024, when it was 47.9 million. Despite the decrease, there are still 10 provinces that will see the highest increase in the number of middle-class people by 2025. The highest increase will be in West Java, with 358,000 people in 2025. Then there's East Java with 152,000 people. Outside of these two provinces, the increase will be less than 100,000. Here's a breakdown of the increase in the number of middle-class people in Indonesia by 10 top provinces in 2025:
- West Java: 358,000 people
- East Java: 152,000 people
- DI Yogyakarta: 63,000 people
- West Kalimantan: 55,000 people
- South Sulawesi: 45,000 people
- Southeast Sulawesi: 36,000 people
- East Kalimantan: 31,000 people
- West Nusa Tenggara: 30,000 people
- North Sumatra: 21,000 people
- South Papua: 11,000 people.
The Mandiri Institute highlighted that the increase in the top provinces is not comparable to the decrease. It noted that South Sumatra is the province with the most severe decline, with 693,000 people in 2025. According to the Mandiri Institute, this pattern shows that the pressure on the middle class is asymmetric and influenced by regional economic conditions. "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 employment 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 World Bank's definition, based on per capita monthly expenditure 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 expenditure exceeds the poverty line. The details:
- 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.
