More than one household may belong to the same household-dwelling unit. A household is formed of all those persons who live together and have meals together or otherwise use their income together.
A comparison between house types reveals that household-dwelling units are piling into blocks of flats. According to Statistics Finland, the number of household-dwelling units living in blocks of flats grew from the previous year by 1.9 per cent or by 22,600 household-dwelling units. In total, 1,214,500 household-dwelling units were living in blocks of flats, nearly one-half of all household-dwelling units.
A household-dwelling unit is formed by persons living permanently in the same dwelling. In the light of annual changes in the numbers of household dwelling-units by house type, the year 2009 appears to be the turning point. In the subsequent years, the number of household-dwelling units has grown clearly faster in blocks of flats than in detached houses and terraced houses. In 2017, the number of household-dwelling units living in detached houses grew by just 0.1 per cent (1,400 household-dwelling units) and that of those living in terraced houses by half a per cent (1,800 household-dwelling units).Statistical release
