HOUSEHOLD AND FAMILY STRUCTURE

A household is defined as one or more people living in a residence. A family is more than one person living together, either married or of the same bloodline. The head of a household is one of the people who owns or rents the residence and was indicated first on the Census questionnaire.

The tendency for people to marry at an older age and the number of married people getting divorced may have contributed to the overall drop in married couples. Also, it may more culturally acceptable for people to not get married at all or to have non-traditional relationships.
