From the Document: "This report analyzes data from the Annual Social and Economic Supplements [hyperlink] (ASEC) of the Current Population Survey [hyperlink] (CPS) to study the effects of the coronavirus pandemic on the financial wellbeing of U.S. households in the middle class and in lower- and upper-income tiers. The latest available survey data, from March 2021, records the household income and work experience of adults in 2020, the first year of the pandemic. The CPS is the U.S. government's official source for monthly estimates of unemployment [hyperlink] and the ASEC, conducted in March each year, is the official source for its estimates of income and poverty [hyperlink]. In this report, the ASEC files were also matched from one year to the next to examine the annual movement of adults across income tiers over the period from 2000 to 2021."
