Annual census surveys 2004-2006 - Only one household in three contains more than two people
In Metropolitan France, the average number of occupants of a dwelling has risen to 2.3 people. A third of dwellings are occupied by one person, and another third by two people. Between 1999 and the beginning of 2005, the changes which have been in progress since the 1970s continued and were accentuated by population ageing. The number of households formed by a single person or by a childless couple rose most strongly. The number of families with children under 25, which fell between 1990 and 1999, stabilised while the proportion of single-parent families continues to grow.
