Age of Householder
Derived from the age responses for the householders. (See the definition of householder under "Household Relationship.") Age and household relationship were determined on a complete-count basis.

The most frequent applications of age of householder in 1980 tabulations involve only two categories: under 65 years old and 65 years and over. More detailed categories appear among the housing tabulations, for example: less than 25 years, 25 to 29, 30 to 34, 35 to 44, 45 to 59, 60 to 64, and 65 years and over. Age of householder is also derivable from age tabulations cross-classified by household relationship (STF 2). Age of householder is derivable from basic records in single years, 15 to 112. Public-use microdata samples also show single years to 99, but group together householders 100 years and over.

Historical comparability
In 1970 and previous censuses, Age of Head was tabulated instead of Age of Householder (see "Household Relationship").

Telephone in Unit
Presence of a telephone in the housing unit, ascertained for occupied units. A telephone in the building but not in the respondent's living quarters is not counted. This item was asked on a sample basis.

Historical comparability
Similar data have been collected since 1960. The 1980 question differs from its 1970 and 1960 counterpart which, designed more as an aid to enumeration, asked whether the household could be reached by phone. The 1980 question refers only to a telephone inside the housing unit. (As an aid to follow up enumeration, respondents were also asked to write their telephone numbers on the back of the questionnaire.)
