The source provides the following information: "Information is collected by a mail and online questionnaire.
The respondents are at least 20 years old and have permanent residency in Finland. There is no upper age limit.
The questionnaire is sent to people drawn by random sampling from the data of the Population Register Centre.
The questionnaire form is available in Finnish, Swedish, Russian and English.
The survey is carried out annually at the national level (sample size 10,000). This allows processing the findings only on the national level, not by any smaller regions.
Once every four years, the sample size is expanded to enable following the changes by counties at a rough level (sample size 3,300/county)."
