For occupied housing units.
Owner-occupied housing units
A housing unit is owner-occupied if respondent living in the unit reported that it was owned or being bought (i.e., owned outright, mortgaged, or being bought on land contract) by someone in the household. (The owner need not be the head of the household and may be either the sole owner or co-owner. )
Cooperatives or condominiums
In 1960, cooperative apartments or houses owned or being bought by someone in the household were classed as part of the owner-occupied category. In 1970, cooperatives or condominiums constitute a separate category from other owner-occupied units.
Renter-occupied housing units
All occupied housing units which were not owner-occupied are classified as renter-occupied.
Occupied units rented for cash
Includes units where respondents reported that money rent was paid or contracted for. The rent may have been paid by persons who were not members of the household; for example friends, relatives, a welfare agency, etc.
Occupied units rented without payment of cash
Includes units where respondents reported the unit was occupied without payment of cash rent and was not being owned or bought; for example, houses or apartments provided free of rent by friends or relatives who owned the property but lived elsewhere, parsonages or houses or apartments occupied by janitors or caretakers in full or partial payment for services, units occupied by tenant farmers or share-croppers who paid no cash rent.
