- The Gini coefficient is the most widely used summary measure of inequality in the distribution of household income; the lower the value, the more equally household income is distributed (Source: Office for National Statistics). The chart shows the Gini coefficient for Great Britain in calendar years between 1961 and 1993, and in financial years from 1993-94 to 2018-19.
- Incomes have been measured net of taxes and benefits, but before housing costs have been deducted, and have been equivalised using the modified OECD equivalence scale.
- Calculations used the Family Expenditure Survey (FES) for data covering the period of 1961 to 1993, and the Family Resources Survey (FRS) for data covering the period of 1994-95 to 2018-19.
