All housing units are classified as occupied or vacant.

Occupied housing units (Households)
back to top
A unit is considered occupied if it was the usual place of residence of the person(s) living in it at the time of enumeration. (See Concept No. 52, place of residence.) Included are units occupied by persons only temporarily absent (on vacation, etc. ) and units occupied by persons with no usual place of residence (for example, migratory workers).

Vacant housing units
back to top
Generally a unit is considered vacant if no persons were living in it at the time of enumeration. However, units temporarily occupied by persons having a usual place of residence elsewhere are classified as vacant; whereas units where the usual residents were only temporarily absent are not classified as vacant.

Newly constructed vacant units are included in the housing inventory if all exterior doors and windows and final usable floors were in place. Vacant units under construction, units being used for nonresidential purposes, units unfit for human habitation, condemned, or scheduled for demolition, and vacant trailers excluded from the housing inventory.

Vacant year-round units
Vacant units which were intended for occupancy at any time of the year, even if used only occasionally throughout the year.

Vacant year-round units
Vacant units intended for year- round occupancy which were offered for sale or rent. In 1960, the concept of available vacant units was used. A unit for rent or for sale was classified as available if it was in sound or deteriorating condition, but not if in dilapidated condition. In 1970, the item on housing condition was not included in the census, so the concept of available unit was not utilized.
