The distribution of income in the United States features heavily in congressional discussions about the middle class, program funding and effectiveness, new and existing target groups, government tax revenue, and social mobility, among other topics. Recently, the level and distribution of U.S. income have also been raised in the context of broader macroeconomic issues, such as economic growth. Accordingly, Congress has sought information on the absolute and relative experience of U.S. households, the range of incomes, and their dispersion. Describing the income distribution involves several important choices about the definition of income and the level at which income data are examined. Income can be constructed narrowly (e.g., earnings only) or broadly (e.g., as the sum of earnings, capital gains, government transfers, and other sources); it can be presented in pre-tax status or reflect taxes paid and tax credits received. Income can be presented at the individual level or represent pooled resources among households, families, or tax units. These choices about how to define income affect the magnitude of income indicators and the shape and range of the U.S. income distribution. For this reason, disagreement over the interpretation of income levels and trends frequently centers on how income is defined. This report is a guide to various measures, indicators, and graphics commonly used to describe the U.S. income distribution. It examines the complexities of income measurement, outlines important definitional and data considerations to bear in mind when using and interpreting income statistics, and reviews descriptive statistics commonly used in analysis. It also discusses the Gini index, a popular summary measure of income dispersion and an appendix presents information on additional summary indicators of income dispersion reported annually by the U.S. Census Bureau. The report provides descriptive analysis of the U.S. income distribution to illustrate various concepts and data presentation strategies. This analysis reveals broad trends, but does not provide an exhaustive study of the distribution of income in the United States. Importantly, the report does not explore potential drivers and impacts of changes to the shape and span of the distribution.show more
