Income quintiles in the context of "Economic indicator"

In economics, distribution is the way total output, income, or wealth is distributed among individuals or among the factors of production (such as labour, land, and capital). In general theory and in for example the U.S. National Income and Product Accounts, each unit of output corresponds to a unit of income. One use of national accounts is for classifying factor incomes and measuring their respective shares, as in national Income. But, where focus is on income of persons or households, adjustments to the national accounts or other data sources are frequently used. Here, interest is often on the fraction of income going to the top (or bottom) x percent of households, the next x percent, and so forth (defined by equally spaced cut points, say quintiles), and on the factors that might affect them (globalization, tax policy, technology, etc.).

Income in the United States is measured by the various federal agencies including the Internal Revenue Service, Bureau of Labor Statistics, US Department of Commerce, and the US Census Bureau. Additionally, various agencies, including the Congressional Budget Office compile reports on income statistics. The primary classifications are by household or individual. The top quintile in personal income in 2022 was $117,162 (included in the chart below). The differences between household and personal income are considerable, since 61% of households now have two or more income earners. Median personal income in 2020 was $56,287 for full-time workers.

This difference becomes very apparent when comparing the percentage of households with six figure incomes to that of individuals. Overall, including all households/individuals regardless of employment status, the median household income was $67,521 in 2020 while the median personal income (including individuals aged 15 and over) was $35,805.

Economic mobility is the ability of an individual, family or some other group to improve (or lower) their economic status—usually measured in income. Economic mobility is often measured by movement between income quintiles. Economic mobility may be considered a type of social mobility, which is often measured in change in income.
