Key Terms and Concepts for Section 9 ¹

Age. Age classification is based on the age of the person at his or her last birthday as of March 2005. A married couple's age is defined as the age of the husband—unless he is under age 55 and the wife is 55 or older, in which case it is the age of the wife.

Aged unit. With age 55 as the cutoff, aged units are defined as married couples living together—at least one of whom is 55 or older—and nonmarried persons 55 or older.

Marital status. Married persons are married and living with their spouse. Nonmarried persons may be divorced, widowed, never married, separated, or married but living apart from their spouse.

Race. The categories White alone, Black alone, and Asian alone reflect respondents who reported only one race. Because of changes to the race category, data on race are not directly comparable to editions prior to 2002. A person's race is his or her reported race. A married couple's race is defined as the race of the husband.

Hispanic origin. Persons of Hispanic origin may be of any race. A married couple is of Hispanic origin if the husband is of Hispanic origin.

Family. A family is a group of two or more people (one of whom is the householder) related by birth, marriage, or adoption and residing together; all such people (including related subfamily members) are considered as members of one family.

Social Security beneficiary. A beneficiary may be receiving retired-worker-benefits, dependents' or survivor benefits, disability benefits, or transitionally insured benefits.

Per capita income. Per capita income is total family income divided by the number of persons in the family.

Relative Importance of Income Source. The relative importance of a source is the ratio of the amount of income from a given source to total income for an aged unit or family. These tables are distributions of persons or aged units by the importance of a given source at the individual unit level.

Poverty. The Census Bureau uses a set of money income thresholds that vary by family size and composition to detect who is poor. If a family's total income is less than that family's threshold, then that family, and every individual in it, is considered poor. The poverty thresholds do not vary geographically, but they are updated annually for inflation with the Consumer Price Index (CPI-U). The official poverty definition counts money income before taxes and excludes capital gains and noncash benefits (such as public housing, Medicaid, and food stamps).
