TEMPO.CO, Jakarta - The Central Statistics Agency (BPS) announced that Indonesia’s level of income inequality, or Gini Ratio, decreased to 0.363 points as of September 2025 compared to the figures recorded in March 2025.
"In September 2025, inequality stood at 0.363, a decrease of 0.012 points from March 2025," said BPS Head Amalia Adininggar Widyasanti in Jakarta on Thursday, February 5, 2026, as reported by Antara.
The level of income inequality is measured using the Gini Ratio on a scale from 0 to 1. The higher the Gini Ratio, the higher the level of inequality within society.
Amalia explained that, regionally, inequality in urban areas remains higher than in rural areas. According to BPS, the Gini Ratio in urban areas is 0.383, a decrease of 0.012 points compared to March 2025. Meanwhile, inequality in rural areas was recorded at 0.295, which is 0.004 points lower than in March 2025.
BPS noted that in September 2025, the province with the highest Gini Ratio was South Papua at 0.426, while the lowest Gini Ratio was recorded in the Bangka Belitung Islands at 0.214.
In addition to the Gini Ratio, another measure of inequality used is the expenditure percentage of the bottom 40 percent income group, known as the World Bank measure. In September 2025, the expenditure share for the lowest 40 percent was recorded at 19.28 percent, an increase of 0.63 percent compared to 18.65 percent in March 2025, and an increase of 0.87 percent compared to 18.41 percent in September 2024.
Regionally, in September 2025, the expenditure percentage for the lowest 40 percent income group in urban areas was recorded at 18.32 percent. This figure increased by 0.68 percent compared to 17.64 percent in March 2025, and by 0.88 percent compared to 17.44 percent in September 2024.
Meanwhile, in rural areas, the expenditure percentage for the lowest 40 percent income group in September 2025 was recorded at 22.09 percent. This figure increased by 0.34 percent compared to 21.75 percent in March 2025, and by 0.70 percent compared to 21.39 percent in September 2024.
