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 average income due to the income distribution. The median can be calculated for household income, personal income 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 can 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. [2]
