Income inequality for older people - EU-SILC survey

The ratio of total income received by the 20 % of the population with the highest income (top quintile) to that received by the 20 % of the population with the lowest income (lowest quintile). Income must be understood as equivalised disposable income.收入最高的20%人口（最高五分位组，top quintile）所获得的总收入，与收入最低的20%人口（最低五分位组，lowest quintile）所获得的总收入的比值。此处所指的收入需理解为等价可支配收入（equivalised disposable income）。
