Share of dwellings erected before 1919

The indicator counts, on 1 January 2011, conventional dwellings by year of construction of the building. Collective housing (e.g. a rest home) and non-standard housing (e.g. a mill) are not included in the indicator. On the other hand, empty dwellings (housing under construction, second residence, etc.) are taken into account. The definition of housing in the Census is also a broader one than that in the cadastre because some dwellings not recognised in the cadastre have been identified as such in the Census, often in situations where it was assumed that a single-family house (recorded in the cadastre) was actually divided into apartments. Note that the few dwellings whose age of the building is indeterminate are well included in the denominator but not in the numerator. Some thematic indicators are also available by statistical sectors on the website of “[\2](\1)” Note: The housing indicators from the 2011 Census are constructed from the cross-section of several databases (the national register, the previous census carried out by survey of the whole population in 2001, the cadastre, etc.).
