Students in the 1991 census
The 1991 census took place during the holidays so most students were at their home address. Therefore the household and relationship information recorded was usually that of their home address.
For any students who were still at their term-time address, the 1991 census form specified that they should put their home address as their usual address. In such cases, they were defined as visitors and we have the household information for this term time address, as long as it was not a communal establishment (e.g. halls of residence). Back at home, the 1991 census form recorded individual and household information on absent usually resident people. These data can be found on the "absent, usually resident members file", though, as we have seen, the usefulness of the absent members' data is limited.
Also, a student living at their term-time address might have seen it as their usual address. Thus, they will be usually resident and those in private households will have household information for that address.
Students were allowed to be employed in the 1991 census. The economic activity variable ECONPO9 only shows students who did not work. Fortunately, the variable ECONPO89 identifies all students whether economically active or not. (See the data dictionary for more details.)
This census was also the first to ask for the term-time address of students as a separate question on the form. Therefore, for students enumerated at their home address, we can identify those who lived elsewhere during term-time. See the variable WERASTU9 in the data dictionary for details.
