**Full name:** Share of residential buildings with 1 and 2 dwellings among residential buildings in % **Algorithm:** Residential buildings with 1 and 2 dwellings <time> / Residential buildings <time> x 100 **Note:** The structure of the residential building stock can be represented by the proportion of single-family and two-family houses. For this purpose, residential buildings with one and two apartments are considered. Since single-family and two-family houses are predominantly privately owned, the indicator is also used as a substitute indicator for home ownership. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

single_two_family_houses

**Full name:** Share of residential buildings with 3 or more dwellings among residential buildings in % **Algorithm:** Residential buildings with 3 or more dwellings <time> / Residential buildings <time> x 100 **Note:** Multi-family houses are understood to be all residential buildings with 3 or more apartments. Since apartments in multi-family houses are predominantly rented and to a lesser extent occupied by the owners themselves, the indicator is also used as a substitute indicator for rental apartments. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

multi_family_houses

**Full name:** Share of dwellings with 1 and 2 rooms among dwellings in % **Algorithm:** Dwellings with 1 and 2 rooms in residential and non-residential buildings <time> / Dwellings in residential and non-residential buildings <time> * 100 **Note:** Apartments and small dwellings with one or two rooms represent an important market segment for single-person and single households. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

one_two_room_apartments

**Full name:** Share of dwellings with 5 or more rooms in % **Algorithm:** Dwellings in residential and non-residential buildings with 5 or more rooms <time> / Dwellings in residential and non-residential buildings <time> x 100 **Note:** Large households/families require apartments with multiple rooms. However, the indicator does not provide information on whether each household member has a room available, as is often demanded in the sustainability debate for personal development. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

five_plus_room_apartments

**Full name:** Share of dwellings in single-family and two-family houses among all dwellings in % **Algorithm:** Dwellings in single-family and two-family houses <time> / Total dwellings <time> x 100 **Note:** The indicator quantifies the extent of the housing stock located in single-family and two-family houses. It thus complements the indicator for the proportion of single-family and two-family houses. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

apartments_in_single_two_family_houses

**Full name:** Share of dwellings in multi-family houses among all dwellings in % **Algorithm:** Dwellings in multi-family houses <time> / Total dwellings <time> x 100 **Note:** The indicator quantifies the extent of the housing stock located in multi-family houses. Multi-family houses are a very heterogeneous group, ranging from 3 to 100 or more apartments per building. It thus complements the indicator for the proportion of multi-family houses. Data before 2011 VZ/GWZ 1987, from 2011 GWZ 2011. With increasing time distance since the GWZ 1987, distortions occur, particularly due to unregistered departures. Additionally, unreported repurposing/consolidations are not included in the statistics.

The dataset "Gebaeude und Wohnungsbestand" describes the structure of the housing market based on key percentage shares. It includes the share of apartments with five or more rooms, the share of residential buildings with one or two apartments among all residential buildings, the share of apartments with one or two rooms among all apartments, the share of residential buildings with three or more apartments among all residential buildings, as well as the share of apartments in single and two-family houses and the share of apartments in multi-family houses, each among all apartments. This provides a detailed view of apartment layouts and building types, enabling insights into settlement structure, urban density, and the supply situation for different household sizes.
