World Inequality Database, top 10% pre-tax national income shareWorld Inequality Lab (World Inequality Database) · Model-based estimateRetrieved 2026-10-27 · Data (zip file) | 45.722024 | Share of pre-tax national income received by the top 10% of adults (age 20 and over), with income split equally between spouses (WID variable sptinc992j, percentile p90p100).Pre-tax national income is income before taxes and transfers but after pensions, scaled to national-accounts national income, so it includes income that households do not report in surveys, such as retained company profits. Raw file: WID_data_SN.csv and WID_metadata_SN.csv in the WID bulk download (wid_all_data.zip, dated 15 October 2026); only the sptincj992 p90p100 rows were kept, in raw/income-inequality-by-country/wid/. Values are WID shares times 100. WID data-quality grade for 2024: 1 (carried forward or backward from the nearest estimate). WID method note for this country: "Figures are obtained by correcting survey tabulations provided by the World Bank (PIP) to account for conceptual discrepancies and the underrepresentation of top incomes. Surveys are available for the following years: 1991, 1994, 2001, 2005, 2011, 2018, 2021. Income shares are interpolated linearly when surveys are available at the beginning and at the end of a given period. Inequality series are extrapolated backwards to 1990 and forwards to 2023 by keeping income shares constant when no data is available for these years." WID builds this series from World Bank (PIP) survey tabulations, corrected for concept and top incomes, so it is not independent of the World Bank line. Because WID derives it from the World Bank survey data in the World Bank line, it is shown but not counted as a separate source. | 3 of 5 checks

Why the numbers differ
- Income concept: WID measures pre-tax national income, which adds income households do not receive in cash or do not report, such as retained company profits, so that the total matches national accounts. The World Bank uses income or consumption as reported in household surveys, and the OECD uses disposable income after taxes and transfers.
- Unit: WID ranks adults and splits income equally between spouses. The World Bank ranks people by household income or consumption per person. The OECD ranks people by household disposable income divided by the square root of household size.
- Data source: surveys miss part of the income at the top. WID adds tax records where it has them and otherwise corrects survey data with models or regional averages; its data-quality grade for each year says which.
- Measure: a Gini index summarises the whole distribution and the top decile's share describes one group, so the two can move differently. The Gini indexes are shown in their own sets for the featured countries.
- Consumption and income: for many countries in Africa and Asia the World Bank survey measures consumption, which is spread more evenly than income, so those shares are not comparable with income shares elsewhere.
- Not independent everywhere: for countries without tax data, such as Nigeria and South Africa, WID builds its series from World Bank survey tabulations, which each row's WID note states.
Common mistakes
- Reading WID figures for the latest year as observed: WID carries the last estimate forward for most countries and grades those years as imputed. (source, retrieved 2026-10-27)
- Comparing a pre-tax share with an after-tax one: taxes and transfers lower the measured inequality, so WID pre-tax shares and OECD disposable-income figures answer different questions. (source, retrieved 2026-10-27)
- Treating the World Bank series as yearly: values exist only for survey years, and the survey measure (income or consumption) can differ between countries and years. (source, retrieved 2026-10-27)
