About the Data—2006
This page displays source information for each of the Census Plus tables in the 2006 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). The 25 Living Cities, a subset of the 100 largest cities, represent the pilot cities in which Living Cities focuses its investments in order to improve urban neighborhoods throughout the country.
Note: The city of Louisville, KY incorporated with its surrounding county, Jefferson County, in 2003. In the 2006 data set, 2000 values for the city of Louisville, KY reflect those for Jefferson County to make them comparable to the 2006 data. Thus, for the city of Louisville estimates taken from the 2000 data set will not match values for 2000 taken from the 2006 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 2006 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 2006 data set.

Race and Ethnicity
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, and Asian—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.

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).
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

Income and Poverty
Income groups—we aggregated each geography’s households into income groups that roughly correspond to national income quintiles in 2006. We used the following categories for the 2006 data set:
- Low-income: household income under $20,000 in the past 12 months (in 2006 inflation-adjusted dollars);
- Lower-middle-income: household income between $20,000 and $34,999 in the past 12 months (in 2006 inflation-adjusted dollars);
- Middle-income: household income between $35,000 and $59,999 in the past 12 months (in 2006 inflation-adjusted dollars);
- Upper-middle-income: household income between $60,000 and $99,999 in the past 12 months (in 2006 inflation-adjusted dollars);
- Upper-income: household income above $100,000 in the past 12 months (in 2006 inflation-adjusted dollars).
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 2006 data set, income values from Census 2000 (for 1999) are adjusted for inflation to 2006 dollars (as reported in the 2006 ACS).

Housing
Multifamily structures—include buildings with five or more housing units.
Median gross rent—in the 2006 data set, 2000 values are adjusted to 2006 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.
