NOTE: Data are based on sample surveys of the noninstitutionalized population, which excludes persons living in institutions (e.g., prisons or nursing facilities); data include military personnel who live in households with civilians but exclude those who live in military barracks. A family household consists of two or more people who are related by birth, marriage, or adoption and are residing together. Own children are never-married sons and daughters, including stepchildren and adopted children, of the householder or married couple. Caution should be used when comparing 2020 and 2021 estimates to those of prior years due to the impact that the coronavirus pandemic had on interviewing and response rates. For additional information about the impact of the coronavirus pandemic on the Current Population Survey data collection, please see https://www2.census.gov/programs-surveys/cps/techdocs/cpsmar21.pdf. Detail may not sum to totals because of rounding.
