Definition
This variable identifies the number of distinct generations in the the household. The number of generations was identified in two ways. First, relationships to the householder as identified by US80B424 were divided into the following generational categories (general codes only):
(1) Parent, Parent-in-law
(2) Householder, Spouse, Sibling, Sibling-in-law
(3) Child, Child-in-law
(4) Grandchild
The number of generations is simply the number of these categories represented in the household.
Second, the family interrelationship pointer variables were examined to provide additional information on "other relatives" and nonrelatives of the householder. For example, two generations exist when someone is linked to a parent as identified by US80B407 and US80B403 ; three generations exist when that parent also has a parent in the household.
