Income inequality in Türkiye eases as Gini index falls in 2025

Income inequality in Türkiye declined slightly over the 2024–2025 period, with the Gini coefficient falling from 0.413 to 0.410, data released by the Turkish Statistical Institute (TurkStat) showed. The indicator, widely used to measure income distribution, signaled a marginal move toward greater balance in household incomes across the country.

How the Gini coefficient is calculated

TurkStat said the index is based on household disposable income, calculated after deducting paid taxes and regular transfers from total annual earnings. The Gini scale ranges from zero, indicating full equality, to one, reflecting complete inequality, and Türkiye’s latest reading marked a 0.003-point improvement compared to the previous year.

Methodology update in 2025 data

With the 2025 results, the statistical authority introduced a revised approach by integrating administrative records. Under the new method, gross income data—after accounting for taxes and social security contributions—were converted into disposable income, aiming to improve accuracy and transparency in income measurement.

Shifts across income groups

The share of total disposable income held by the highest-income 20% slipped to 48%, down 0.1 points, while the lowest-income quintile saw its share rise to 6.4%, up 0.1 points year-on-year. Officials said the figures point to a limited but notable adjustment in income distribution trends across Türkiye.
