Note: Table reports the unweighted number and percentage of CPS repondents in October of one year (the shaded box) who responded to the CPS in December of that year (the outlined box). Under “Year X,” entries report the month and year in which respondents were in MIS1. Because of the rotation group structure, not all respondents in October are eligible to respond in December The column labeled “plausible” omits apparent matches when respondents’ sex or race/ethnicity differs or when their age differs implausibly.
