In order to identify how the evolution of society affects Swedes’ attitudes and behaviour, the SOM Institute started its National SOM study in 1986. National SOM addresses three areas - society, opinion and mass media - and consists of several parallel surveys. All surveys include a large number of questions related to politics, society, media and social background, but their areas of focus differ. In 2012, the following questionnaires are distributed: Sweden 1 focusing on politics and society; Sweden 2 focusing on media and culture; Sweden 3 focusing on life style and health; Sweden 4 focusing on economy and welfare


The main purpose is to establish time series that enable researchers to analyse how various changes in society affect people's attitudes and behaviour.
