Using the internal March CPS, we create and in this paper distribute to the larger research community a cell mean series that provides the mean of all income values above the topcode for any income source of any individual in the public use March CPS that has been topcoded since 1976. We also...

Although the vast majority of US research on trends in the inequality of family income is based on public-use March Current Population Survey (CPS) data, a new wave of research based on Internal Revenue Service (IRS) tax return data reports substantially higher levels of inequality and faster...

Using internal and public use March Current Population Survey (CPS) data, we analyze trends in US income inequality (1975-2004). We find that the upward trend in income inequality prior to 1993 significantly slowed thereafter once we control for top coding in the public use data and censoring in...

Using the Census Bureau's internal March Current Population Surveys (CPS) file, we construct and make available variances and cell means for all topcoded income values in the public-use version of these data. We then provide a procedure that allows researchers with access only to the public-use...

Researchers considering levels and trends in the resources available to the middle class traditionally measure the pre-tax cash income of either tax units or households. In this paper, we demonstrate that this choice carries significant implications for assessing income trends. Focusing on tax...

With data from the March CPS and using shift-share analysis, we analyze the factors that account for changes in post-tax post-transfer income during each of the past four recessions. What distinguishes the Great Recession is that drops in employment rather than wage earnings drove income...

Inconsistent censoring in the public-use March CPS limits its usefulness in measuring labor earnings trends, as previous approaches for imputing topcoded earnings systematically understate top earnings. Using Pareto estimation methods with less-censored internal data, we create an enhanced...

Since 2012 the Congressional Budget Office has included an estimate of the market value of government-provided health insurance coverage in its measures of household income. We follow this practice for both public and private health insurance to capture the impact of greater access to...

Access to IRS personal income tax records improves researchers' ability to track U.S. income and inequality, especially at the very top of the distribution (Piketty and Saez 2003). However, rather than following standard Haig-Simons income definitions, tax form income measures were designed to...

We evaluate progress in President's Johnson's War on Poverty. We do so relative to the scientifically arbitrary but policy relevant 20 percent baseline poverty rate he established for 1963. No existing poverty measure fully captures poverty reductions based on the standard that President Johnson...
