1. The Historical Statistics of Switzerland, 1978-2018. A short history
The 2018 re-launch and revision of the online version of the Historical Statistics of Switzerland (HSSO) represents the last step in an already long history. This working paper contains detailed information about the various research projects that were developed at the University of Zurich from 1978 onwards in order to produce first an «analog» collection of historical data (published in book form in 1996) and then, from 2003 onwards, a «digital» version of this database.
