The SNC database consists of the following datasets:
- SNC standard file: The SNC standard file includes 265 of the most important variables of the Swiss National Cohort.
- 2000 census: All people living in Switzerland on the 5.12.2000 had to fill out several questionnaires: one for each person (personal record), one for the household (household record with information on number of people living together etc.). Additionally, house owners had to fill out a questionnaire for the building (building record (only if applicable) with information on the building, like number of flats, heating etc.).
- 1990 census: Similar to 2000 census.
- From 2010 onwards, the census is register-based and performed yearly. Several variables (e.g. religion, education, profession) are not included in the yearly census data anymore.
- Mortality data: All death records from 1991 up to 2018 have been linked to the corresponding census. The records contain socio-demographic information as well as information about causes of death (up to 2017).
- Population movement statistics: Since 2010, data about live births, stillbirths, marriages and divorces have also been linked to the census data.
- Structural surveys: For the structural survey a sample of at least 200’000 residents are asked to fill out a written questionnaire each year since 2010. These structural surveys are an addition to the register-based censuses and have been linked to the SNC standard file.
- Swiss health survey (SHS) 1992: A sample of around 15’000 persons have been asked about their health status and health-related behaviours. The SNC data was linked to the SHS data.
- Swiss neighbourhood index (Swiss-SEP): Based on the 2000 census data and the structural surveys 2012-2015 we developed a area-based index of socio-economic position.
