Median income

The median income is the income amount that divides a population into two groups, half having an income above that amount, and half having an income below that amount. It may differ from the mean (or average) income. Both of these are ways of understanding income distribution. Median income can be calculated by household income, by personal income, or for specific demographic groups. When taxes and mandatory contributions are subtracted from income, the result is called net or disposable income. The measurement of income from individuals and households, which is necessary to produce statistics such as the median, can pose challenges and yield results inconsistent with aggregate national accounts data. For example, an academic study on the Census income data claims that when correcting for underreporting, U.S. median gross household income was 15% higher in 2010 (table 3).

Median equivalised household disposable income (OECD)

The median equivalised household disposable income is the median of the disposable income which is equivalised by dividing income by the square root of household size; the square root is used to acknowledge that people sharing accommodation benefit from pooling at least some of their living costs. The median equivalised disposable income for individual countries corrected for purchasing power parity (PPP) for 2021 in United States dollars is shown in the below table.
