Labeling errors were discovered in Table 14-1 and Table 14-2 (Inmigration, Outmigration, and Net Domestic Migration by Metropolitan Status, by Sex, Age, Race and Hispanic Origin, Relationship to Householder, Educational Attainment, Marital Status, Nativity, Tenure, and Poverty Status, and for Persons 16 and Over, Income in 2020, Labor Force Status, Major Occupation Group, and Major Industry Group: 2020 to 2021). Migration flows within metropolitan areas were incorrectly labeled as flows within principal cities or balances, respectively, when the second-level column label should have referred to the other component of metropolitan areas (instead of the same component). When the first-level column label indicated nonmetropolitan areas, the second-level column labels should have listed principal cities of metro areas first on the left, then balances of metro areas second on the right (instead of in the opposite order). These tables were reproduced and replaced. None of the numeric estimates were changed. Please replace any previously downloaded versions with the corrected version.
