Notes:
- The 90/10 income inequality ratio represents how many times larger income at the 90th percentile is compared with income at the 10th percentile. The chart shows the 90/10 income inequality ratio in calendar years between 1961 and 1992, and in financial years from 1993-94 to 2018/19.
- All statistics are based on the Institute for Fiscal Studies (IFS) calculations using the Family Expenditure Survey (FES) (1961 to 1993 inclusive) and the Family Resources Survey (FRS) thereafter (1994-95 to 2018-19).
- Incomes are measured net of direct taxes and benefits, before housing costs have been deducted, and equivalised using the modified OECD equivalence scale.
- Figures relate to Great Britain households.
