Background variables immigrant panel

The demographics and other general characteristics of Immigrant panel households are measured every month using a separate questionnaire, known as the Household Box. For every Immigrant panel household, a single contact person completes this questionnaire. The Household Box needs to be completed when joining the panel, before the household can start completing other questionnaires. Thereafter, the contact person is presented the household box every month to enter any changes that may have occurred. From every field work period, a data file containing details from the household box is made available.
