The survey on diversity and coexistence in Switzerland has been conducted every two years since 2016 by the Federal Statistical Office (FSO) in conjunction with the population census.
It enables the systematic monitoring of racial and discriminatory attitudes in Switzerland. A leaner survey focusing on specific topics is conducted in alternate years.
You can find the results of the 2018 survey on the FSO website.
This data is included in the Report on racial discrimination in Switzerland (PDF, 2 MB, 26.11.2019).
