Year Householder Moved Into Unit
The data on year householder moved into unit were obtained from answers to long-form questionnaire Item 36, which was asked on a sample at occupied housing units. These data refer to the year of the latest move by the householder. If the householder moved back into a housing unit he or she previously occupied, the year of the latest move was reported. If the householder moved from one apartment to another within the same building, the year the householder moved into the present apartment was reported. The intent is to establish the year the present occupancy by the householder began. The year that the householder moved in is not necessarily the same year other members of the household moved in, although in the great majority of cases an entire household moves at the same time.
Median year householder moved into unit
Median year householder moved into unit divides the distribution into two equal parts: one-half of the cases falling below the median year householder moved into unit and one-half above the median. Median year householder moved into unit is computed on the basis of a standard distribution (see the "Standard Distributions" section under "Derived Measures"). Median year householder moved into unit is rounded to the nearest whole number. (For more information on medians, see "Derived Measures".)
In 1960 and 1970, this question was asked of every person and included in population reports. This item in housing tabulations refers to the year the householder moved in. Since 1980, the question has been asked only of the householder.
