About this data

Source: Office for National Statistics (ONS), Effects of taxes and benefits on household income: financial year ending 2025, Table 9; Institute for Fiscal Studies, via the Chartbook of Economic Inequality

• The Gini coefficient measures inequality on a scale from 0 to 100: 0 if everyone had the same income, 100 if one person had all of it.
• Disposable income is household income from all sources after income tax, National Insurance and council tax, including cash benefits, adjusted for household size (equivalised).
• Both series come from household surveys but differ slightly in method: ONS uses the Living Costs and Food Survey and the Household Finances Survey; the IFS series uses the Family Expenditure Survey and, from 1994/95, the Family Resources Survey, and runs to 2014.
• From 1994/95, figures are for financial years, shown by the year they end.
