Persons aged 15 years and more staying in households for duration of 12 months or more.

The following categories of people are considered as members of a household:
• persons present in a household (registered for a permanent or temporary stay, staying or intending to stay without registering for 12 months and more),
• persons absent (the total duration of actual and planned absence is considered ) for duration shorter than 12 months (e.g. persons staying temporary abroad, living in institutional households or other households in the country for duration shorter than 12 months).
The survey does not cover the members of households who stayed 12 months or longer abroad or in institutional house-holds (such as lodging-houses for employees, student hostels, boarding schools, social welfare homes, etc.) and homeless people.
