Field help: (2018) The primary place of residence has existed since

Specify since when you have maintained your own household in your home town.

Having one's own household requires a financial contribution to the costs of living (ongoing costs of running the household), in addition to owning an apartment under one's own right as owner or tenant or under common or derived law as a spouse, partner or cohabitant as well as a roommate.

It is not enough if you merely occupy one or more rooms in your parents' household free of charge or if you are provided with a flat in your parents' house free of charge. The financial contribution to the household expenses must be proven and is not assumed in general, even for adult children living with their parents or with one of their parents. A financial contribution to the household costs with insignificant amounts is not sufficient to qualify as an own household.
