| The chart above shows aggregate total wealth by decile and the breakdown by type of wealth. |
| The terms tercile, quartile, quintile and decile should refer to the percentiles which divide the distribution into 3, 4, 5, or 10 equal parts, respectively. |
| Each decile contains one tenth of the wealth distribution – from the least wealthy households in the first decile to the wealthiest in the tenth. |
| No special social security contribution is payable up to the fifth income decile. |
| The annual income bias is especially high in the lowest annual income decile, equaling almost 10 percent of income. |
| The increase in tax paid by the lowest income decile would be £1 per week with a 10 per cent reduction in consumption. |
