About the Data—2000

This page displays source information for each of the Census Plus tables in the 2000 data set. It also further defines several terms used in the reports and raw data available for download. Source information and glossary terms are organized by topic area. Definitions for additional terms can be found on the Census Bureau's Factfinder website.

For information on comparability issues and differences between the 2000, 2005, 2006, and 2007 data sets, see the section on Census versus ACS: Important differences between the data sets in the User Guide.

General Terms


Cities
Data for cities represent values for incorporated place(s). The 100 largest cities in the U.S. are those with populations of at least 190,000 in 2000, from Irving, TX (population 191,615) to New York, NY (population 8,008,278).

Note: The city of Augusta, GA incorporated with its surrounding county, Richmond County, between 1990 and 2000. Values for the city of Augusta-Richmond County, GA for 1990 reflect those for Richmond County net of the towns of Blythe, GA, and Hephzibah, GA, which remain separately incorporated places within Richmond County.

In addition, the city of Louisville, KY incorporated with its surrounding county, Jefferson County, in 2003. In the 2005 data set, 2000 values for the city of Louisville, KY reflect those for Jefferson County to make them comparable to the 2005 data. Thus, for the city of Louisville estimates taken from the 2000 data set will not match values for 2000 taken from the 2005 data set.

Counties
Counties represent the primary legal subdivisions of most states. The 100 largest counties in the United States, based on population counts as of Census 2000, range in size from Bernalillo County, NM (556,678) to Los Angeles County (9,519,338). Two geographies among the 100 largest counties are not technically counties but are considered primary legal subdivisions; Washington, DC is considered equivalent to a county for statistical purposes, and the city of Baltimore, MD, which is independent of any county, is considered a primary legal subdivision in Maryland.

Metro areas
Metropolitan Statistical Areas (a.k.a. “metro areas”) are designated by the Office of Management and Budget (OMB) and consist of a highly-populated core area plus the surrounding communities that exhibit a high degree of social and economic integration with that core area. The Census Plus site uses OMB’s December 2003 definitions of metropolitan statistical areas. These metro areas are composed of counties in one or more states. The 100 largest metro areas, based on population counts as of Census 2000, range in size from Modesto, CA (446,997) to New York-Northern New Jersey-Long Island, NY-NJ-PA (18,323,002).

States
The primary legal subdivision of the U.S., all 50 states are included on the Census Plus website.

Population

Note: Population counts for the 2000 data set come from the decennial census, while 2005 population counts and trends use data from the U.S. Population Estimates Program. Therefore, counts from the 2000 data set will not match population counts for 2000 from the 2005 data set.

Race and Ethnicity

Segregation/dissimilarity index—these values, calculated by the Brookings Institution using Census 2000 data on race and ethnicity (see source data below), can be interpreted as the proportion of one group that would have to move to another neighborhood within the given geography to achieve the same population distribution as the other group. Higher indices reflect greater degrees of physical separation between the two groups.

Note: Calculating dissimilarity indices requires tract-level data on race and ethnicity. Because the 2005 American Community Survey does not report data for geographies with populations under 65,000, the segregation indices are not available in the 2005 data set.

Share of the population by race and ethnicity—with the exception of “two or more races,” counts and shares for each race category—white, black/African American, Asian/Pacific Islander—reflect that race “alone,” and do not include individuals that identify as Hispanic or Latino. The Hispanic or Latino category is a stand-alone ethnicity, reflecting individuals of any race who self-identify as Hispanic or Latino.

Note: Because of the adjustments made and the slightly different categories used in the 2005 data set, race and ethnicity data taken from the 2000 data set reports will not match data taken from the 2005 reports for the year 2000.

Age

Percent change in population by age—users should keep in mind that changes in the number of persons in a particular age category between census surveys reflect not only age-specific migration patterns in different geographies, but also larger demographic patterns like the size of generational cohorts. For instance, nationwide the number of 45 to 54 year-olds grew by 49 percent between 1990 and 2000. This increase occurred because Baby Boomers born between 1946 and 1955 occupied that age group in 2000, a much larger cohort than 45 to 54 year-olds in 1990 (who were born during the Depression and World War II-era years of 1936 to 1944).

Note: Because of comparison issues between the 2000 and 2005 data sets, more detailed age trends are available in the 2000 data set than in the 2005 data set. In addition, age data taken from the 2000 data set reports will not match 2000 data taken from the 2005 reports.

Dependency ratio—this ratio represents the number of children and seniors for every 100 adults aged 18 to 64 within a geography. As such, it offers a rough indication of how many "dependent" persons a geography’s working-age population must help to support.

Households and Families

Household types—household/family types are organized into six categories within this topic area:

  • Married couples with children include households headed by a married couple that contain one or more sons or daughters by birth, marriage, or adoption, who are under age 18.
  • Married couples without children include all other households headed by a married couple.
  • Other families with children include households headed by an individual with no spouse present that contain one or more sons or daughters by birth, marriage, or adoption, who are under age 18. Typically, these households are "single-parent" families.
  • Other families without children include all other households with individuals related to the head of the household by birth, marriage, or adoption. These households may include, for example, a single parent living with an adult child, or an unmarried adult caring for an elderly parent within the household.
  • Individuals living alone occupy their housing units alone.
  • Other nonfamilies include households with two or more unrelated individuals, such as roommates or unmarried partners.

Education

Share of population with bachelor's degree/high school diploma—these reflect the population with at least the named level of attainment. For instance, individuals with a high school diploma include those with a high school diploma only, plus those with some college/associate's degree, a bachelor's degree, a master's degree, a professional degree (e.g., J.D., M.D.), or a doctorate.

Note: Trend reports on change in the share of population with a bachelor’s degree/high school diploma are not available in the 2005 data set. Because the 2000 data includes the group quarters population, the estimates are not comparable.

Income and Poverty

Income groups—we aggregated each geography’s households into income groups that roughly correspond to national income quintiles in 2000. We used the following categories for the 2000 data set:

  • Low-income: household income under $20,000 in 1999;
  • Lower-middle-income: household income between $20,000 and $34,999 in 1999;
  • Middle-income: household income between $35,000 and $49,999 in 1999;
  • Upper-middle-income: household income between $50,000 and $74,999 in 1999;
  • Upper-income: household income above $75,000 in 1999.

While these categories do not reflect the difference between the cost of living in a geography and the nation as a whole, or the differences among geographies themselves, they do reflect the degree to which a geography's households are concentrated in one or more parts of the national income distribution.

Median household income—in the 2000 data set, income values from the 1990 census (for 1989) are adjusted for inflation to 1999 dollars (as reported in Census 2000).

Housing

Multifamily structures—include buildings with five or more housing units.

Median gross rent—in the 2000 data set, 1990 values are adjusted to 2000 dollars. Gross rent includes average amounts paid by the renter for utilities and fuels.

Renters with housing-cost burdens—these numbers include those paying at least 30 percent of their income for gross rent.
