Construction-year histogram
Parcels with a building by construction period, as a share of the 78’626 parcels with a known year. The periods are not equally long, so read the bars as shares of the stock, not as building activity per year.

How to read these figures
The parcel data links every parcel to the federal building register (GWR). A parcel counts once, with the construction year of its newest building. Where the register gives only a construction period, the middle of the period is used.
The figures count parcels with a building, not individual buildings. A parcel with several buildings counts once, and a parcel without a building is not counted.
Building age is 2026 minus the construction year. Every share divides by the parcels with a known construction year.
