This is how Germany lives: The new CASA typology divides nationwide every household into one of 98 classes. It is objective, further differentiable, address-specific, representative and transferable.

Would you have thought that Germany’s largest household group is found with only 8.4% in 1-2 family houses in rural towns? This is one of numerous new insights from the CASA typology “living”.

For this, each individual house was precisely characterized by a unique variety of mostly official criteria (construction, age, outline, size, height, location, etc.). The resulting CASA typology “living” contains about 19 million buildings, in which around 40 million households of Germany live. It defines 14 statistically relevant basic types of living such as “multi-party house in a block” or “business with 1 household”. Moreover, the typology contains the official division according to the seven BBSR settlement types from “rural community” to “metropolis”, so that this results in 98 representative types of residential buildings nationwide.


The subdivision can be further differentiated. A large 1-2 family house can be distinguished from e.g. a small one or a semi-detached house can be distinguished from a mid-terrace house. The latter shows i.a. significantly lower energy requirements. As a result, the CASA typology “living” describes with high precision and objectively the real housing situation of all households. Additionally, the CASA typology has integrated an intra-municipal centrality model for inner city planning purposes, that is, households can be evaluated according to their distance to the next supply centers (daily/weekly needs) to an accuracy of one meter.

By means of Small Area Methods (SAM) and the definition of statistical twins, an estimation of any economically or scientifically relevant phenomenon, both regionally and locally, becomes possible. Thus, it is possible to recalculate many other socio-demographic characteristics such as disposable income, social class or share of foreigners in the settlement block in a comprehensible and reproducible manner.

For these reasons, the CASA typology is mainly used, among total market analysis and CRM, in marketing research in order to locate target groups address-specific, to consult them and to apply them to the population (statistically comprehensible).

Apart from the CASA typology “living” presented here, infas 360 already developed a CASA typology “working” which is currently further refined.
