In this question we have to fill-in a table with several codes to establish the relation of the private household members and the reference person.

Every classical family must have a reference person.

And as for reference person we understand the family member that is considered as such by the other members, has to be a resident in the dwelling, must be 18 or older and preferentially is the responsible for the dwelling.

This reference person must always be a dwelling resident, but may be absent on the census moment.

In the families where these conditions don't apply use the oldest person as the reference person.

On the Column 2 you must collect the complete name of the reference person and the first and last name of all the others.
