Socio-economic data on grid level (SUF 5.1). House type

The variable house type indicates the size of a house and is based on the sum of the households and the number of firms in a house. Houses with particularly many commercial addresses are categorised as commercially used houses. Single- and two-family homes are distinguished according whether the house type in that road (section) is homogenous or not. There are 7 house types in the data: single- and two-family homes in homogenous road sections, single- and two-family homes in heterogeneous road sections, 3-5 family homes, 6-9 family homes, blocks of flats with 10-19 households, multi-storey buildings with 20 and more households, mainly commercially used houses. The house type allows for conclusions on geographical information, such as the location in an urban area: while cities predominantly consist of multi-family houses, the countryside is shaped by single- and two-family homes (microm 2016, p. 32).
