Definitions of Demographic Terms in Demographic Data Items

This is a dictionary guide to demographic terms, as used in Census demographics databases. These are predominantly Census demographics terms, although some terms related to Consumer Spending Potential and Business Data are also included

Definition of Demographic terms

1-Unit, Detached
Housing structure type: Is a 1-unit structure that is detached from any other house; that is, with open space on all four sides. Such structures are considered detached even if they have an adjoining shed or garage. A 1-family house that contains a business is considered detached as long as the building has open space on all four sides. Mobile homes to which one or more permanent rooms have been added or built also are included.
1-Unit, Attached
Housing structure type: Is a 1-unit structure that has one or more walls extending from the ground to the roof separating it from adjoining structures. In row houses (sometimes called townhouses), double houses, or houses attached to nonresidential structures, each house is a separate, attached structure if the dividing or common wall goes from ground to roof.
2 or More Units
Housing structure type: Are units in structures containing 2 or more housing units, further categorized as units in structures with 2, 3 or 4, 5 to 9, 10 to 19, 20 to 49, and 50 or more units.
Age
The age classification is based on the age of the person in complete years as of April 1, 2000. The age of the person usually was derived from their date of birth information. Their reported age was used only when date of birth information was unavailable.
Data on age are used to determine the applicability of some of the sample questions for a person and to classify other characteristics in census tabulations. Age data are needed to interpret most social and economic characteristics used to plan and examine many programs and policies. Therefore, age is tabulated by single years and by many different groupings, such as 5-year age groups.
Aggregate
The total amount; the sum of all values in a distribution. For example the Aggregate Households calculates the total number of Households within a specified area.
Aggregate Income
The total money income, expressed as millions of dollars, for all persons in an area regardless of household status.
American Indian, Eskimo or Aleut
A person having orgins in any of the original peoples of North and South America (including Central America) and who maintain tribal affiliation or community attachment. Includes persons who classified themselves as such in one of the following race categories: American Indian, American Indian Tribe (Iroquois, Sioux, Colorado River, Flathead), Eskimo (Arctic Slope, Inupiat and Yupik), or Aleut (Alutiiq, Egegik and Pribilovian).
Ancestry
The data on ancestry represent self-classification by people according to the ancestry group(s) with which they most closely identify. Ancestry refers to a person's ethnic origin, descent, "roots", heritage, or the place of birth of the person or the person's parent or ancestors before their arrival in the United States.
Asian
A person having origins in any of the original peoples of the Far East, Southeast Asia, or the Indian subcontinent including, for example, Cambodia, China, India, Japan, Korea, Laos, Malaysia, Pakistan, the Philippine Islands, Thailand, and Vietnam.

Average
The number found by dividing the sum of all quantities in a distribution by the total number of quantities. For example, Aggregate Household Income divided by Total Households equals Average Household Income. (Average is also known as "Mean.")
Average Family Size
Is calculated by dividing the number of persons in families by the number of families. Any person in a household who is related to the householder is considered a member of the family.
Average Household Income
The average or mean income is obtained by dividing total household income by the total number of households.
Average Household Size
Is calculated by dividing the number of persons in households by the number of households.

Householder
When the U.S. Census form for a household is filled out, one person is designated as the householder. In most cases, this is the person, or one of the persons, in whose name the home is owned, being bought or rented. If there is no such person in the household, any adult household member 15 years old and over could be designated as the householder. Householder may also be referred to as "Head of Household." Two types of householder are distinguished:
  1. 1) a family householder, living with one or more persons related to him or her by birth, marriage, or adoption, and
  2. 2) a nonfamily householder, living alone or with nonrelatives only.

Information derived from the long form is referred to as sample data and is tabulated for geographic entities as small as block group level. In the 2010 Census, the long form was replaced by the ongoing American Community Survey.
Male Householder, No Wife Present
A family with male head of householder with no spouse present.
Marital Status
Refers to the status at the time of the enumeration and is tabulated only for those persons 15 years old and over.

Couples who live together were allowed to report the marital status they considered the most appropriate.
Married-Couple Family
A family in which the householder and his or her spouse are enumerated as members of the same household.
Means of Transportation to Work
Refers to the principle mode of travel the person used to get from home to work. Persons who used more than one means of transportation were asked to report the one used for the longest distance during the work trip.
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 median value. For example, if the median age is 35.3, half the population is younger than 35.3 and the other half is older than 35.3.
Median
This measure represents the middle value (if n is odd) or the average of the two middle values (if n is even) in an ordered list of n data values. The median divides the total frequency distribution into two equal parts: one half of the values in a distribution falls above the median value and one half falls below it. For example, if the median household income is $44,389, half the households earn less than $44,389 and the other half earn more than $44,389.
Median Income
The median represents the middle of the income distribution, dividing the income distribution into two equal parts, one having incomes above the median and the other having incomes below the median. Median income is calculated for both household income and family income distributions.
Mobile Home
Housing structure type: Both occupied and vacant mobile homes to which no permanent rooms have been added are counted in this category. Mobile homes used only for business purposes or for extra sleeping space and mobile homes for sale on a dealer's lot, at the factory, or in storage are not counted in the housing inventory. In 1990, the category was "mobile home or trailer."

The category consists mainly of students, housewives, retired workers, seasonal workers enumerated in an 'off' season who were not looking for work, institutionalized persons, and persons doing only incidental unpaid family work.
Occupation
Describes the type of work that a person performs while on the job. The classifications were developed to be consistent with the 1980 Standard Occupational Classification (SOC) Manual. Occupation data are for employees working in the study area, whether or not they are residents within its boundaries.
Occupation: Unclassified
Unclassified occupations are of workers employed in the establishments that are not classified by SIC code, usually new businesses that could not be classified in any major industry group due to insufficient information.
Occupied Housing Unit
A housing unit is classified as occupied if it is the usual place of residence. If all persons staying in the unit at the time of the census have their usual place of residence elsewhere, the unit is classified as vacant.
Per Capita Income
The average money income per man, woman, and child regardless of age, labor force status, or group quarters status.
Place of Birth
The data on place of birth were derived from answers to long-form questionnaire Item 12 which was asked of a sample of the population. Respondents were asked to report the U.S. state, Puerto Rico, U.S. Island Area, or foreign country where they were born. People not reporting a place of birth were assigned the state or country of birth of another family member or their residence 5 years earlier, or were imputed the response of another person with similar characteristics. People born outside the United States were asked to report their place of birth according to current international boundaries. Since numerous changes in boundaries of foreign countries have occurred in the last century, some people may have reported their place of birth in terms of boundaries that existed at the time of their birth or emigration, or in accordance with their own national preference. The place of birth question for residents of Puerto Rico was identical to the question on the stateside questionnaires. The same code lists were used to code the responses and similar edits were applied.
Other Race

Race
The concept of race as used by the Census Bureau does not denote any clear-cut scientific definition of biological stock. The data for race represent self-classification by people according to the race with which they most closely identify. Furthermore, it is recognized that the categories of the race item include both racial and national origin or socio-cultural groups. The racial categories of the 1990 census (before modification) are provided below:
  • White
  • Black
  • American Indian, Eskimo, or Aleut
  • Asian or Pacific Islander
  • Other

Renter Occupied
All occupied housing units that are not owner occupied.
Retail Businesses
The industry classification used for retail business is that of the Office of Management and Budget in its 1987 edition of the "Standard Industrial Classification Manual." Included are the more traditional "over-the-counter" type retailing that usually takes place in stores and showrooms, together with such semi-industrial retail categories as lumber yards, plant nurseries, mobile home dealers, gas stations, mail order houses, fuel and ice dealers, and bottled gas dealers.
Selected Monthly Owner Costs
The data on selected monthly owner costs were obtained from answers to long-form questionnaire Items 45a-d, 47b, 48b, 49, 50, 52, and 53b, which were asked on a sample basis at owner-occupied housing units. Selected monthly owner costs are the sum of payments for mortgages, deeds of trust, contracts to purchase, or similar debts on the property (including payments for the first mortgage, second mortgage, home equity loans, and other junior mortgages); real estate taxes; fire, hazard, and flood insurance on the property; utilitie (electricity, gas, and water and sewer); and fuels (oil, coal, kerosene, wood, etc.). It also includes, where appropriate, the monthly condominium fees or mobile home costs (installment loan payments, personal property taxes, site rent, registration fees, and license fees). Selected monthly owner costs were tabulated separately for all owner-occupied units, specified owner-occupied units, and owner-occupied mobile homes and, usually, are shown separately for units "with a mortgage" and for units "not mortgaged."
Site-based
The employees' primary workplace is a single location.
Some Other Race
Includes all other responses not included in the "White," "Black or African American," American Indian or Alaska Native," "Asian," and "Native Hawaiian or Other Pacific Islander" race categories. Respondents providing write-in entries such as multiracial, mixed, inter-racial, or a Hispanic/Latino group (for example, Mexican, Puerto Rican, or Cuban) in the "Some other race" write-in space are included in this category.

Standard Industrial Classification (SIC) Code
A four-digit numeric code established by the U.S. government in conjunction with U.S. businesses to designate various industries as defined by their functions and products. The SIC is intended to cover the entire field of economic activities, namely: agriculture, forestry, fishing, hunting and trapping, mining, construction, manufacturing, transportation, communication, electric, gas, and sanitary services, wholesale and retail trade, finance, insurance, and real estate, personal, business, repair, and other services, and public administration. The SIC codes employed by Scan/US are from the 1987 "Standard Industrial Classification Manual." SIC codes are used by direct marketers to segment lists and to target promotions. The government uses them to report and track business-related census data. The first two digits indicate a major industrial classification; the second two digits, an industrial subclass. For example, SIC code 2300 represents a manufacturer of clothing; code 2352, a manufacturer of hats and caps. What the code cannot tell the direct marketer is whether a business is engaged only in the activity defined by the SIC code, or whether the code represents a primary business activity. In the latter case, there may be other marketing opportunities not identified by the SIC code. Note, however, an analysis using Scan/US business classifications may help uncover these opportunities.
TBA Dealers
Tire, battery and accessory dealers.
Telephone Service Available
The data on telephones were obtained from answers to long-form questionnaire Item 41, which was asked on a sample basis at occupied housing units. Households with telephone service have a telephone in working order and are able to make and receive calls. Households whose service has been discontinued for nonpayment or other reasons are not counted as having telephone service available.
Tenure
The classification of all occupied housing units as either renter or owner occupied. Tenure is also cross tabulated by age of the householder, race and Hispanic.
Time Leaving Home to Go to Work
The departure time refers to the time of day that the person usually left home to go to work during the reference week.
Total Employed Population
Total employed population is the male and female civilian employed population. Includes all civilians who were 'at work' or 'with a job but not at work' during the reference week.
Total Workers
Total workers is tabulated differently and not equivalent to the total employed population. Total workers as the journey-to-work base includes those in the armed forces but excludes those 'with a job but not at work' during the reference week.
Travel Time to Work
The total number of minutes that it usually took the person to get from home to work during the reference week.
Two or more races
People may have chosen to provide two or more races either by checking two or more race response check boxes, by providing multiple write-in responses, or by some combination of check boxes and write-in responses. The race response categories shown on the questionnaire are collapsed into the five minimum race groups identified by the OMB, and the Census Bureau "Some other race" category. For data product purposes, "Two or more races" refers to combinations of two or more of the following race categories: 1. White 2. Black or African American 3. American Indian or Alaska Native 4. Asian 5. Native Hawaiian or Other Pacific Islander 6. Some Other Race There are 57 possible combinations involving the race categories shown above. Thus, according to this approach, a response of "White" and "Asian" was tallied as two or more races, while a response of "Japanese" and "Chinese" was not because "Japanese" and "Chinese" are both Asian responses.
Unemployed
All civilians 16 years old and over are classified as unemployed if they were neither "at work" nor "with a job but not at work" during the reference week, were looking for work during the last 4 weeks, and were available to start a job. Also included as unemployed were civilians 16 years old and over who: did not work at all during the reference week, were on temporary layoff from a job, had been informed that they would be recalled to work within the next 6 months or had been given a date to return to work, and were available to return to work during the reference week, except for temporary illness. Examples of job seeking activities were:
  • Registering at a public or private employment office
  • Meeting with prospective employers
  • Investigating possibilities for starting a professional practice or opening a business
  • Placing or answering advertisements
  • Writing letters of application
  • Being on a union or professional register.
Units In Structure
In determining the units in structure, all housing units, both occupied and vacant, are counted. Stores and office space are excluded. A structure is a separate building that either has open spaces on all sides or is separated from other structures by dividing walls that extend from the ground to the roof.
Vacancy Status
Vacancy status and other characteristics of vacant units were determined by enumerators obtaining information from landlords, owners, neighbors, rental agents and others. Vacant units are also classified as "For Rent," (vacant unit could be offered for rent or for sale), "For Sale Only," "Rented or Sold, Not Occupied," "For Seasonal, Recreational, or Occasional Use," "For Migrant Workers" and "Other Vacant."
Vacant Housing Units
A housing unit is vacant if no one is living in it at the time of enumeration, unless its occupants are only temporarily absent.
Vehicles Available
Includes passenger cars, vans, and pickup and panel trucks of one-ton capacity or less kept at home and available for the use of household members. Vehicles rented or leased for more than one month or more, company vehicles and police and government vehicles that are kept at home and are used for non-business purposes.

White
A person having origins in any of the original peoples of Europe, the Middle East, or North Africa. Includes persons who indicated their race as "White" or reported entries such as Canadian, German, Italian, Lebanese, Near Easterner, Arab, or Polish.
White Collar
White collar occupations include executives, managers, administrators, professionals, technologists and technicians, sales workers, clerks, and administrative support workers.
Worker
The terms "worker" and "work" appear in connection with several subjects: employment status, journey-to-work, class of worker, and work status. Their meaning varies and, therefore, should be determined by referring to the definition of the subject in which they appear. When used in concepts "Workers in Family," "Workers in Family in 1999," and "Full-Time, Year-Round Workers," the term "worker" relates to the meaning of work defined for the "Work Status in 1999" subject.
Year Householder Moved Into Unit
This data refers to the latest time of occupancy by the householder.
Year Structure Built
Was asked at both occupied and vacant housing units and refers to when the building was first constructed, not when it was remodeled, added to or converted.
Business/Family Drops
U.S. Postal Service terminology. For a carrier route, the number of business or families served at drop sites. (A drop site is a single delivery point or receptacle that services multiple "families." Examples of drop sites include a single door slot shared by two families, a box on a wall for duplexes, or a boarding house or fraternity at which mail is delivered to the door for subsequent distribution. Mail for drop sites is distributed internally by the site. Commercial mailbox companies are also classified as drop sites because the carrier delivers the mail to one point, and it is distributed to specific boxes by the company.)
