Aleut
Includes persons who indicated their race as "Aleut" or reported entries such as Alutiiq, Egegik, and Pribilovian
American Indian
Includes persons who indicated their race as "American Indian," entered the name of an Indian tribe, or reported such entries as Canadian Indian, French-American Indian, or Spanish-American Indian.
Eskimo
Includes persons who indicated their race as "Eskimo" or reported entries such as Arctic Slope, Inupiat, and Yupik
American Indian Reservation
American Indian entity with boundaries established by treaty, statute, and/or executive or court order in the US. Federal and individual state governments established reservations as territory over which American Indians have governmental jurisdiction. These entities are designated as colonies, communities, pueblos, rancherias, reservations, and reserves. The Federally recognized reservations, their names, and their boundaries are identified for the US Census Bureau by the Bureau of Indian Affairs (BIA), an agency in the U.S. Department of the Interior; state governments identify the names and boundaries of state reservations.
American Indian Trust Land
Land held in trust by the Federal government for either a tribe (tribal trust land) or an individual member of that tribe (individual trust land. Such land always is associated with a specific Federally recognized reservation or tribe, but may be located on or off the reservation. The Census Bureau recognizes and tabulates data separately only for off-reservation trust lands. The BIA identifies and provides maps of these areas for use by the Census Bureau.
ANC
Section 450b(e) of title 25 U.S.C. "Indian tribe" means any Indian tribe, band, nation, or other organized group or community, including any Alaska Native village or regional or village corporation as defined in or established pursuant to the Alaska Native Claims Settlement Act (85 Stat. 688) (43 U.S.C. 1601 et seq.), which is recognized as eligible for the special programs and services provided by the United States to Indians because of their status as Indians.
Area
The size, in square miles, recorded for each geographic entity. Square miles may be multiplied by 2.59 to convert an area measurement to square kilometers. Land Area was calculated by the Census Bureau from the specific set of boundaries recorded for each entity in its geographic data base. ZIP Code area is calculated by Geographic Data Technology, Inc. The reliability of any area measurement figure is limited by the inaccuracy inherent in (1) the location and shape of the various boundary features in the data base, and (2) rounding affecting the last digit in all operations that compute and/or sum the area measurements.
Asian
Refers to people having origins in any of the original peoples of the Far East, Southeast Asia, or the Indian subcontinent. It includes people who indicated their race or races as "Asian Indian", "Chinese", "Filipino", "Korean", "Japanese", "Vietnamese", or "Other Asian", or wrote in entries such as Burmese, Hmong, Pakistani, or Thai.
Average
The number found by dividing the sum of all quantities by the total number of quantities. For example, Aggregate Income divided by Total Households equals Average Household Income.
Average Household Income
The average or mean income is obtained by dividing total household income by the total number of households. Because the average is influenced strongly by extreme values in the distribution, it is especially susceptible to the effects of sampling variability.
Average Household Size
Average household size is calculated by dividing the number of persons in households by the number of households.
Average Income of Households
Includes the income of the householder and all other persons 15 years and over in the household, whether related to the householder or not. Because many households consists of only one person, average household income is usually less than average family income.

Subdivisions of census tracts, each generally contain between 600 and 3000 people, with an optimum size of 1,500 people.
Census County Division (CCD)
Census county divisions are county subdivisions that were delineated by the U.S. Census Bureau, in cooperation with state and local officials for purposes of presenting statistical data. CCDs have been established in 21 states where there are no legally established minor civil divisions (MCDs), where the MCDs do not have governmental or administrative purposes, where the boundaries of the MCDs change frequently, and/or where the MCDs generally are not known to the public. CCDs have no legal functions and are not governmental units.
Census Tract
A small, permanent subdivision of a county with homogeneous population characteristics, status and living conditions.
Centroid
The center of a map object.
Certified Small Business

Own Children
in a family are sons and daughters, including stepchildren and adopted children, of the householder.
Related Children

Citizen
People who indicate that they were born in the United States, Puerto Rico, a U.S. Island Area, or abroad of a U.S. citizen parent(s) are citizens. People who indicate that they are U.S. citizens through naturalization are also citizens. Naturalized citizens are foreign-born people who identify themselves as naturalized. (Naturalization is the conferring, by any means, of citizenship upon a person after birth.)
Citizenship status
There are five categories of citizenship status: 1) Born in the United States; 2) Born in Puerto Rico or another outlying area of the U.S.; 3) Born abroad of U.S. citizen parents; 4) Naturalized citizens; 5) Non-citizens.
Not a citizen
People who indicate they are not U.S. citizens.
City
Type of incorporated place in 49 states and the District of Columbia. In 23 states and the District of Columbia, some or all cities are not part of any Minor Civil Division (MCD), and the Census Bureau also treats these as county subdivisions, statistically equivalent to MCDs.
Class of worker
All people over the age of 15 who have been employed at any time are asked to designate the type of work normally done or the work performed most regularly. Occupations and types of work are then broken down into the following classes.
Government Workers
Includes people who are employees of any local, state, or federal governmental unit, regardless of the activity of the particular agency. For some tabulations, the data are presented separately for the three levels of government. Employees of foreign governments, the United Nations, or other formal international organizations controlled by governments should be classified as "Federal Government employee."
Private Wage and Salary Workers
Includes people who worked for wages, salary, commission, tips, pay-in-kind, or piece rates for a private-for-profit employer or a private-not-for-profit, tax-exempt, or charitable organization. Self-employed people whose business was incorporated are included with private wage and salary workers because they are paid employees of their own companies. Some tabulations present data separately for these subcategories: "For profit," "Not-for-profit," and "Own business incorporated."
Salaried/Self-Employed
In tabulations that categorize persons as either salaried or self-employed, the salaried category includes private and government wage and salary workers; self-employed includes self-employed people and unpaid family workers.
Self-Employed Workers
Includes people who worked for profit or fees in their own unincorporated business, profession, or trade, or who operated a farm.
Unpaid Family Workers
Includes people who worked 15 hours or more without pay in a business or on a farm operated by a relative.
Consolidated Metropolitan Statistical Area (CMSA)
Geographic entity defined by the Federal Office of Management and Budget (OMB) for use by Federal statistical agencies in the US. An area becomes a CMSA if it meets the requirements to qualify as a metropolitan statistical area (MSA), has a population of 1,000,000 or more, if component parts are recognized as primary metropolitan statistical areas (PMSAs), and local opinion favors the designation. Whole counties are components of CMSAs outside of New England, where they are composed of cities and towns instead.
Converted Approach Count
Approach counts (counts on each directional leg of an intersection going into an intersection) or turning movement counts (each lane at an intersection including the direction the cars are turning) factored to an average daily number.
Coordinate
A set of numbers that designate location in a given reference system, such as x,y in a planar coordinate system or an x,y,z in a three dimensional coordinate system. Coordinates represent locations on the Earth's surface relative to other locations.
Core Based Statistical Area (CBSA)
The Office of Management and Budget (OMB) reviewed the Metropolitan Area standards in 1999 and 2000. The new standards replace the current metropolitan area classification with a Core-Based Statistical Area (CBSA) classification. The new Core-Based Statistical Area (CBSA) consists of a county containing an Incorporated Place or Census Designated Place with a population of at least 10,000 along any adjacent counties that have at least 25% of employed residents of the county who work in the CBSAs core or central county. CBSAs are categorized as being either Metropolitan (core population of at least 50,000) or Micropolitan (core population between 10,000 and 50,000). This allows common statistics to be collected for less urban areas of the nation. These two county-based CBSA definitions will cover approximately 90% of the U.S. population.
Corporation
A Corporation is the most common form of business organization, is created under the laws of a state as a separate legal entity that has privileges and liabilities that are distinct from those of its owners. This form of business is primarily characterized by the limited liability of its owners, the issuance of shares of easily transferable stock, and existence as a going concern.
County
The primary political administrative subdivision of a state, the county is widely used for marketing purposes for the following reasons: 1) The range and reliability of currently available data below the state level is greatest at the county level. 2) County geographic boundaries are rarely altered. 3) Complete national coverage is achieved by summarizing all counties. 4) County boundaries are readily identifiable. For Louisiana, parishes are used in lieu of counties; for Alaska, boroughs and census areas. The District of Columbia is treated as a single county unit. In Virginia, all cities are by law independent of counties; therefore they are treated as county units. The cities of Baltimore, MD, St. Louis, MO and Carson City, NV are also independent and therefore classified as counties.
Custom Radius
A specific street address or intersection with data aggregated for 1 or multiple radii from it or bands around it.
Density
Population divided by the county's square miles of land area. A simple basis for relating population to a county's size. Thus, two counties with the same population can have sharply divergent densities because of difference in land area. The figure may suffer because the land area will include railroad freight yards, wildlife preserves, industrial parks and other nonresidential areas, resulting in a misleading density level.
Designated Market Area (DMA)
The formal term for what is more commonly known as a TV or broadcast market. Definitions for DMA's are supplied by Nielsen Media Research that generates ratings for broadcast programming. DMA's are selected by totaling the viewer hours of TV stations whose signals reach a particular county with total hours, then converted to a percentage share of all viewing hours. DMA's are named for the market of origin of the station(s) with the largest share of viewer hours, and all counties whose largest viewer share is given to stations in that same market of origin are grouped together under that DMA. NOTE: Because of the reach of broadcast signals, DMA's don't always conform to whole-county geography like metro markets or newspaper markets. In certain cases, Nielsen splits counties, treating each portion as if it were a separate county. Each county, or portion thereof, is allocated to a single DMA, eliminating any geographic overlap. DMA's cover the whole U.S., except for parts of Alaska.
Disabled Business Enterprise (DIS)
At least 51% owned and controlled by a handicapped individual or service-disabled individual. A handicapped individual is a person with a physical, mental or emotional impairment, defect, ailment, disease or disability of a permanent nature, which any way limits the selection of any type of employment for which the individual(s) would otherwise be qualified or qualifiable.
Disabled Veteran Business Enterprise (DVET)
At least 51% owned and controlled by one or more Disabled Veterans. The home office must be located in the United States and the home office cannot be a branch or subsidiary of a non-US corporation, firm or other non-US based business. The individual(s) must be a veteran of US military services and has a service-connected disability of at least 10% or more.
Disadvantage Business Enterprise (DBE)
As defined by the US Department of Transportation. At least 51% owned and controlled by individual(s) who are socially and economically disadvantaged as defined by the DBE Regulation 49 CFR Parts 23 and 26. All eligible owners must certify they are members of a disadvantaged group (eligible ethnic group and/or female). Additionally, the owner(s) assets cannot exceed $750,000, excluding the assets of the business seeking the DBE certification and the owner(s) primary residence.
Earnings
Earnings is defined as the algebraic sum of wage or salary income and net income from self-employment. Earnings represent the amount of income received regularly before deductions for personal income taxes, Social Security, bond purchases, union dues, Medicare deductions, etc.
Educational attainment (25+)
Refers to the highest level of education completed in terms of the highest degree or the highest level of schooling completed. This includes designations such as Less than Grade 9, Grade 9-12, High School Graduate, Some College-No Degree, Associate Degree, Bachelor's Degree, and Graduate Degree.
Employed
Employed includes all civilians 16 years old and over who were either (1) "at work" -those who did any work at all during the reference week as paid employees, worked in their own business or profession, worked on their own farm, or worked 15 hours or more as unpaid workers on a family farm or in a family business; or (2) were "with a job but not at work" -those who did not work during the reference week but had jobs or businesses from which they were temporarily absent due to illness, bad weather, industrial dispute, vacation, or other personal reasons. Excluded from the employed are people whose only activity consisted of work around the house or unpaid volunteer work for religious, charitable, and similar organizations; also excluded are people on active duty in the United States Armed Forces. The reference week is the calendar week preceding the date on which the respondents completed their questionnaires or were interviewed. This week may not be the same for all respondents.
Estimated Counts
Traffic counts updated by a source entity from an older year to a more current year based solely on historical data or local expertise.
Ethnicity
In general, the Census Bureau defines ethnicity or origin as the heritage, nationality group, lineage, or country of birth of the person or the person 's parents or ancestors before their arrival in the United States. People who identify their origin as Spanish, Hispanic, or Latino may be of any race. According to the revised Office of Management and Budget standards, race is considered a separate concept from Hispanic origin (ethnicity) and, wherever possible, separate questions should be asked on each concept.
Federal Information Processing Standards (FIPS) Code
FIPS codes are assigned for a variety of geographic entities, including American Indian and Alaska Native area, congressional district, county, county subdivision, metropolitan area, place, and state. The objective of the FIPS code is to improve the use of data and avoid unnecessary duplication and incompatibilities in the collection, processing, and dissemination of data.
Foreign Born
Foreign-born population
People who are not U.S. citizens at birth.
Native population
People born in either the United States, Puerto Rico, or a U.S. Island Area such as Guam or the U.S. Virgin Islands, or people born in a foreign country to a U.S. citizen parent(s).

GOV
Government Entity: Public sector entities and organizations.
Green Certified
A business that is certified by a agency as having met all of their standard that award eligibility within one of the following categories, process, product, building, design, energy, food, community and tourism.
Group quarters (GQ)
The Census Bureau classifies all people not living in households as living in group quarters. There are two types of group quarters: institutional (for example, correctional facilities, nursing homes, and mental hospitals) and non-institutional (for example, college dormitories, military barracks, group homes, missions, and shelters).
Group quarters population
Those people residing in group quarters as of the date on which a particular survey was conducted. The Census Bureau recognizes two general categories of people in group quarters:
Institutionalized population
The institutionalized population includes people under formally authorized supervised care or custody in institutions at the time of enumeration. Such people are classified as "patients or inmates" of an institution regardless of the availability of nursing or medical care, the length of stay, or the number of people in the institution. Generally, the institutionalized population is restricted to the institutional buildings and grounds (or must have passes or escorts to leave) and thus have limited interaction with the surrounding community. Also, they are generally under the care of trained staff who have responsibility for their safekeeping and supervision.
Non-institutionalized population
The non-institutionalized population includes all people who live in group quarters other than institutions. Some examples of these types of group quarters may be college dormitories, rooming houses, religious group homes, communes, and halfway houses.
Hispanic Origin
The OMB defines Hispanic or Latino as "a person of Cuban, Mexican, Puerto Rican, South or Central American, or other Spanish culture or origin regardless of race." In data collection and presentation, federal agencies are required to use a minimum of two ethnicities: "Hispanic or Latino" and "Not Hispanic or Latino." For Census 2000, the questions on race and Hispanic origin were asked of every individual living in the United States. The question on Hispanic origin asked respondents if they were Spanish, Hispanic, or Latino based on self-identification.
Historically Black University or College (HBCU)
Postsecondary academic institutions founded before 1964 whose educational mission has been historically the education of Black Americans.
Historically Underutilized Business Zone (HUBZone)
As defined by the US SBA HUBZone Empowerment Program. Qualifying businesses must meet small business size criteria and must be located in distressed areas.
Household
A household consists of all the people occupying a single housing unit under the 2000 Census rules. A housing unit is defined as a house, apartment, mobile home, group of rooms, or a single room that is occupied. In addition, the members of a household need not be related, and a single person living alone in a housing unit is also considered a household.
Family household (Family)
A family includes a householder and one or more people living in the same household who are related to the householder by birth, marriage, or adoption. All people in a household who are related to the householder are regarded as members of his or her family. A family household may contain people not related to the householder, but those people are not included as part of the householder's family in census tabulations. Thus, the number of family households is equal to the number of families, but family households may include more members than do families. A household can contain only one family for purposes of census tabulations. Not all households contain families since a household may comprise a group of unrelated people or one person living alone.
Non-family household
a household containing a group of unrelated people or one person living alone. Persons who are not counted as members of households comprise those living in group quarters such as college dormitories, military barracks, rooming houses, long-term-care hospitals, nursing homes, and prisons.
Household Population
Total Household Population is a head count estimate of all people living in a given geographic area as of January 1, 1997 minus people living in group quarters, such as colleges, hospitals, institutions, and nursing homes, as well as armed forces personnel permanently assigned to the area.
Household size
The total number of people living in a housing unit.
Household type and relationship
Households are classified by type according to the sex of the householder and the presence of relatives. Examples include: married-couple family; male householder, no wife present; female householder, no husband present; spouse (husband/wife); child; and other relatives.
Householder
The person, or one of the people, in whose name the home is owned, being bought, or rented. If there is no such person present, any household member 15 years old and over can serve as the householder for the purposes of the census. Two types of householders are distinguished: a family householder and a non-family householder. A family householder is a householder living with one or more people related to him or her by birth, marriage, or adoption. The householder and all people in the household related to him are family members. A non-family householder is a householder living alone or with non-relatives only.
Housing unit
A house, an apartment, a mobile home or trailer, a group of rooms, or a single room occupied as separate living quarters, or if vacant, intended for occupancy as separate living quarters. Separate living quarters are those in which the occupants live separately from any other individuals in the building and which have direct access from outside the building or through a common hall. For vacant units, the criteria of separateness and direct access are applied to the intended occupants whenever possible.
Income
Income is the aggregate of wages and salaries, net farm and nonfarm self-employment income, interest, dividends, net rental and royalty income, Social Security and railroad retirement income, other retirement and disability income, public assistance income, unemployment compensation, Veterans Administration payments, alimony and child support, military family allotments, net winnings from gambling, and other periodic income. Receipts from the following sources are not included as money income: money received from the sale of property (unless the recipient is engaged in the business of selling property); the value of income 'in kind' from food stamps, public housing subsidies, medical care, employer contributions for persons, etc.; withdrawal of bank deposits; money borrowed; tax refunds; exchange of money between relatives living in the same household; gifts and lump-sum inheritances, insurance payments, and other types of lump-sum receipts.
Income of Households
Includes the income of the householder and all other persons 15 years old and over in the household, whether related to the householder or not. Because many households consist of only one person, average household income is usually less than average family income.
Index
An index is a method comparing the value of a demographic variable for a selected geography to a base geography. The mathematical equation is; the value of a selected demographic variable divided by the geography base multiplied by 100. It is important to note some variables aren't indexable; for example, Population. Indexable variables are calculated variables Averages, Medians and Percents.
Industry (population data)
Information on industry relates to the kind of business conducted by a person's employing organization. For employed people the data refer to the person's job during the reference week. For those who worked at two or more jobs, the data refer to the job at which the person worked the greatest number of hours. Some examples of industrial groups shown in products include agriculture, forestry, and fisheries; construction; manufacturing; wholesale or retail trade; transportation and communication; personal, professional and entertainment services; and public administration.
Labor Surplus Jurisdiction
Labor Surplus generally defined for a Civil Jurisdiction rather than the entire MSA where the average unemployment number is 20% higher than the average U.S. unemployment rate in the last two calendar years.
Latitude
Used to describe the North-South position of a point as measured usually in degrees or decimal degrees above or below the equator. Latitude lines are the horizontal lines on a map that increase form 0 degrees at the Equator to 90 degrees at both the North (+90.0 degrees) and South (-90.0 degrees) poles.
Layer
Basic element of a map. A map typically consists of several superimposed layers. Each map layer refers to one specific table of information.
Legend
The reference area on a map that lists and explains the colors, symbols, line patterns, shadings, and annotations used on the map. The legend often includes the scale, origin, orientation, and other map information.
Limited Liability Company (LLC)
A Limited Liability Company (LLC) is a flexible form of enterprise, authorized by state statute, that blends the tax flexibility of a partnership with the personal liability protection of a corporation. LLCs do not need to be organized for profit. Owners of an LLC are called members. Since most states do not restrict ownership, members may include individuals, corporations, other LLCs and foreign entities. There is no maximum number of members. Most states also permit "single member" LLCs, those having only one owner. A few types of businesses generally cannot be LLCs, such as banks and insurance companies.
Limited Liability Partnership (LLP)
A Limited Liability Partnership (LLP) is a partnership in which some or all partners (depending on the jurisdiction) have limited liability. It therefore exhibits elements of partnerships and corporations. In an LLP one partner is not responsible or liable for another partner's misconduct or negligence. This is an important difference from that of an unlimited partnership. In an LLP, some partners have a form of limited liability similar to that of the shareholders of a corporation. Although an LLP can be used in many fields, it is most commonly used in law or accounting firms.
Limited Partnership
A Limited Partnership is a form of partnership similar to a general partnership, except that in addition to one or more general partners (GPs), there are one or more limited partners (LPs), who are normally only liable to the extent of their investments. It is a partnership in which only one partner is required to be a general partner.
Longitude
Used to describe the East-West position of a point. The position is reported as the number of degrees east (to -180.0 degrees) or west (to +180.0 degrees) of the prime meridian (0 degrees). Represented by vertical lines running from the North to South poles. Lines of longitude are farthest apart at the Equator and intersect at both poles, and therefore, are not parallel.
Marital Status
Adults are generally classified by marital status as being married, never married, separated, divorced or widowed.
Master Limited Partnership
A limited partnership that is publicly traded on a securities exchange. It combines the tax benefits of a limited partnership with the liquidity of publicly traded securities.
Media Market
(See Designated Market Area.)
Median
A calculated value that divides the distribution in an area into two equal parts. One half falls above the value and one half falls below. For example, if the median age is 21, half the population is younger than 21 and the other half is older than 21.
Median Age
This measure divides the age distribution into two equal parts: one half of the cases falling below the median value and one-half above the value.
Median Income
The median represents the middle of the income, dividing the income distribution into two equal parts, one having income above the median and the other having income below the median.
Metropolitan Statistical Area (MSA)
A geographic area with a significant population nucleus, along with any adjacent communities that have a high degree of economic and social integration with that nucleus.
Minor Civil Division (MCD)
The primary governmental or administrative divisions of a county or county equivalent in many states. MCDs represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions. MCDs are variously designated as American Indian reservations, assessment districts, boroughs, charter townships, election districts, election precincts, gores, grants, locations, magisterial districts, parish governing authority districts, plantations, precincts, purchases, road districts, supervisor's districts, towns, and townships.

Persons reporting in the "Other Race" category and providing write-in entries such as multiracial, multiethnic, mixed, interracial, Wesort, or a Spanish/Hispanic origin group (such as Mexican, Cuban, or Puerto Rican) are included here.
Out of Business
A firm is flagged as "Suspected Out of Business" when one or more conditions suggest that the business is no longer operating. Most small business failures do not result in a consumer or commercial bankruptcy so there is no definitive legal filing to indicate the date of the business failure. In lieu of a bankruptcy filing we monitor various operating conditions and note anomalies such as undeliverable address, a disconnected telephone number, business license expirations and others. Such events have historically proven to correlate highly with firms going out of business. Our research has shown that in most cases that firms reported as suspected out of business are no longer operating, however approximately 10-15% of the time these firms are in fact active, therefore you should remember that there is a possibility that the firm is still operating. The earliest out-of-business records in the database go back to 1975.
Owner-occupied housing unit
A housing unit is owner occupied if the owner or co-owner lives in the unit even if it is mortgaged or not fully paid for.

Incorporated places have legal descriptions of borough (except in Alaska and New York), city, town (except in New England, New York, and Wisconsin), or village. The Bureau of the Census defines a place as a concentration of population; a place may or may not have legally prescribed limits, powers, or functions. This concentration of population must have a name, be locally recognized, and not be part of any other place.

It includes people living in group quarters, such as colleges, hospitals, institutions, and nursing homes, as well as armed forces personnel permanently assigned to the area.
Population By Age and Sex
Male and female population totals for 11 age groups are useful for marketers who seek to aim their products or services at specific sales targets. For example, the 12to 17-year-old population is a favorite target of those marketing soft drinks and compact disks. Several of the age groups are also associated with lifestyle stages such as the preschoolers (0-5 years), teenagers (12-17 years), and young adults (18-24 years), which are critical to the formulation of marketing strategies.

People who felt they fell into none of those categories could choose the "other" option, or they could indicate a combination of more than one race. These categories differ from 1990 principally because Asian has become a separate category and because multiple races was not an option 10 years ago. Note that The Census Bureau considers "Hispanic" an ethnicity, not a race. Anyone who selected a race on their 2000 Census forms also reported whether they were Hispanic or non-Hispanic. The racial categories of the 2000 census (before modification) are provided below:
