Average Persons Per Household is calculated by taking the total population less the population living in group quarters and dividing it by the number of households (or occupied units).
Housing Units by Year Built: The number and percentage of houses that were built during specific ranges of years beginning in 1939 and ending in the year the 1990 census was taken. This variable includes both vacant and occupied units.  Of particular interest are the subcategories: Built 1940 to 1949 and 1939 or earlier. These figures represent the percentage of very old housing. In metropolitan or urban areas a high percentage represented by this subcategory could signal the transition of housing from single to multiple dwellings or low density to high density population. Check your Trends report under the Density projections.
Households by Heating Type: Provides insight about the type of housing in a community.
Households By Number of Persons: The number of persons in all occupied units (owned or rented).
Households by Presence of Telephone: The number and percentage of households that do and do not have telephones.
Median Rent: The median rent from the universe of all rental properties.
Occupied Units by Type: A house, apartment, mobile home or trailer, group of rooms, or single room occupied as a separate living quarter. The number of households and the number of occupied units will be the same. Occupied Units does not include group quarters.
Owner Occupied: The owner or co-owner of the unit lives in the unit even if it is mortgaged or not fully paid for.
Renter Occupied: The unit is rented by the persons who live in it.
Population by Urban Versus Rural: Classifies areas as either urban or rural.
Urban: Persons living in urbanized areas and in places of 2,500 or more inhabitants outside of urbanized areas.
Rural: Everyone else, not necessarily farm residence. Can be a small town as long as it is outside of an urbanized area and has fewer than 2,500 inhabitants.
Single to Multiple Unit Ratio: The number of single units compared to the multiple units. If the ratio is minimal, this indicates an area where the number of multiple unit dwellings is close to the number of single unit dwellings. Where the ratio is broad (e.g. 18 to 1), it indicates a community which is predominately made up of single family units.
Structures by Number of Units: Occupied units plus vacant units. Single Unit is a single family dwelling detached from any other structure with open space on all four sides. They may also include a one unit structure which has one or more walls extending from ground to roof separating it from adjoining structures. 2 to 9 Units, 10 to 19 Units, 20 to 49 Units and 50 or more Units are multiple unit dwellings, usually apartments or condominiums. Mobile Home indicates non-permanent living dwellings to which no permanent rooms have been added. Other category is for any living quarters occupied as a housing unit that does not fit the previous categories. Examples include houseboats, railroad cars, campers and vans.
Vacant Units by Type: Vacancy status and other characteristics of vacant units were determined by census enumerators obtaining information from landlords, owners, neighbors, rental agents, and others. Vacant units are subdivided according to their housing market classification.
For Rent: Vacant units offered "for rent" and vacant units offered either "for rent or for sale."
For Sale: Vacant units being offered "for sale only," including units in cooperatives and condominium projects if the individual units are offered "for sale only."
Seasonal: Vacant units used or intended for use only in certain seasons or for weekend or other occasional use throughout the year.
Other: Vacant units that do not fall into one of the above categories.
1990 Owner Occupied Property Values: Owner-occupied property values in 1990.
1990 Median Property Value: The point where there are as many properties valued under the median as there are valued over the median.
