The Swiss National Cohort (SNC) is a long-term, census-based, multipurpose cohort and research platform. It is based on the linkage of individual data from the 1990 census to the 2000 census. This basic database has been enhanced with information from the mortality records from 1991 up to 2008. Because in Switzerland no personal identification number exists, the method of probabilistic record linkage was used to assign a record from the mortality statistic to a record in the Census data.
This linkage of the datasets allows to follow people in Switzerland over a long period and is therefore suitable for longitudinal studies.
The Swiss National Cohort is funded by the Swiss National Science Foundation (SNSF). The first period run from the 1st of July 2006 to the 30th of June 2011. The SNSF supports the SNC for a second period, starting on the 1st of July 2011 to the end of June 2014.
