The table below shows the distribution of disposable income by quintiles (percentage share of total disposable income) in a hypothetical economy from 2018 to 2023.
| Year | Lowest 20% | Second 20% | Third 20% | Fourth 20% | Top 20% | Total (%) |
|---|---|---|---|---|---|---|
| 2018 | 9 | 13 | 18 | 24 | 36 | 100 |
