About this data
- 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.
- Original income is income from work, private pensions and investments. Gross income adds cash benefits such as the State Pension, Universal Credit and Child Benefit. Disposable income then subtracts income tax, National Insurance and council tax. All are adjusted for household size.
- Part of the rise in original income inequality reflects more retired households, who have little original income but receive the State Pension.
- From 1994/95, figures are for financial years, shown by the year they end.
