The category "percent in carpools" includes workers who reported that two or more persons usually rode to work in the vehicle during the reference week. The data on "percent using public transportation" includes workers who used a bus or trolley bus, streetcar or trolley car, subway or elevated, railroad, ferryboat, or taxicab.

The reference week is the calendar week preceding the date on which the respondents completed the questionnaire or were interviewed by enumerators.
Families (Family Households) - Includes a householder and one or more persons living in the same household who are related to the householder by birth, marriage, or adoption. All persons in a household who are related to the householder are regarded as members of his or her family. All persons in a household who are related to the householder are regarded as members of his or her family. 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 persons or one person living alone.
Gross Rent - Monthly contract rent plus the estimated average monthly cost of utilities and fuels, if these are paid by the renter.
Gross Rent as a Percentage of Household Income - A computed ratio of monthly gross rent to monthly household income.
Household - Includes all the persons who occupy a housing unit. Persons not living in households are classified as living in group quarters. In sample tabulations, the count of households may differ from the count of occupied housing units as a result of the weighting process.
Householder - Includes, in most cases, the person or one of the persons in whose name the home is owned, being bought, or rented and who is listed in column 1 of the census questionnaire. If there is no such person in the household, any adult household member 15 years old an over could be designated as the householder.
Housing Unit - Includes a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or, if vacant, is intended for occupancy) as separate living quarters.
Income in 1989 - Information on money income received in the calendar year 1989 was requested from persons 15 years and over. "Total income" is the algebraic sum of the amounts reported separately for wage or salary income; net nonfarm self-employment income; net farm self- employment income; interest, dividend, net rental or royalty income; Social Security or railroad retirement income; public assistance or welfare income; retirement or disability income; and all other income.
Industry - Information on industry relates to the kind of business conducted by a person's employing organization. For employed persons 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.

Metropolitan Area - A metropolitan area contains either a place with at least 50,000 inhabitants or an urbanized area and a total population of at least 100,000 (75,000 in New England). Contiguous parishes (cities and towns in New England) are included if they have close social and economic links with the area's population nucleus.
Nonfamily Household - Includes a householder living alone or with nonrelatives only.
Not Enrolled, Not High School Graduate - Includes persons of compulsory school attendance age or above who were not enrolled in school and were not high school graduates; these persons may be taken as "high school dropouts." There is no restriction on when they "dropped out" of school and they may have never attended high school.
Not in Labor Force - All persons 16 years old and over who are not classified as members of the labor force. This 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 (less than 15 hours during the reference week).
Owner Occupied - 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. The owner or co-owner must live in the unit.
Per Capita Income - The mean income computed for every man, woman, and child in a particular group. It is derived by dividing the total income of a particular group by the total population.
Persons Per Room - "Persons per room" is obtained by dividing the number of persons in each occupied housing unit by the number of rooms in the unit. Persons per room is rounded to the nearest hundreth. The figures shown refer, therefore, to the number of occupied housing units having the specified ratio of persons per room.
Poverty Status in 1989 - Poverty status was determined for all persons except institutionalized persons, persons in military group quarters and in college dormitories, and unrelated individuals under 15 years old. These groups were excluded from the denominator when calculating poverty rates. Poverty statistics were based on a definition originated by the Social Security Administration in 1964 and modified by federal interagency committees in 1969 and 1980 and prescribed by the Office of Management and Budget. The income cutoffs used by the Census Bureau to determine the poverty status of families and unrelated individuals included a set of 48 thresholds arranged in a two-dimensional matrix consisting of family size cross-classified by presence and number of family members under 18 years old. The average poverty threshold for a family of four persons was $12,674 in 1989.
Related Children - Includes own children ( a never-married child under 18 years who is a son or daughter by birth, a stepchild, or an adopted child of the householder) and all other persons under 18 years of age in the household, regardless of marital status, except the spouse of the householder.
Renter Occupied - All occupied housing units which are not owner occupied, whether they are rented for cash rent or occupied without payment of cash rent, are classified as renter occupied.
School Enrollment - Persons were classified as enrolled in school if they reported attending a "regular" public or private school or college at anytime between February 1, 1990, and the time of enumeration. The question includes instructions to "include only nursery school, kindergarten, elementary school, and schooling which would lead to a high school diploma or college degree" as regular school. Schools supported and controlled primarily by religious organizations or other private groups are defined as private. Persons who were enrolled and reported completing nursery school or less were classified as enrolled in "preprimary school" which includes kindergarten. Similarly, enrolled persons who had completed at least kindergarten, but not high school, were classified as enrolled in "elementary or high school." Enrolled persons who reported completing high school or some college or having received a post-secondary degree were classified as enrolled in "college."
Unemployed - Civilians 16 years old and over are classified as unemployed if they (1) were neither "at work" nor "with a job but not at work" during the reference week, and (2) were looking for work during the last four weeks, and (3) were available to accept a job. Also included as unemployed are civilians who did not work at all during the reference week and were waiting to be called back to a job from which they had been laid off.
Urban and Rural Population - As defined for the 1990 census, the urban population comprises all persons living in urbanized areas and in places of 2,500 or more persons outside urbanized areas. The population not classified as urban constitutes the rural population. Rural population is subdivided to include rural farm population which comprises all rural households or farms.
