How is the KOTT survey conducted?

The survey is conducted once every four years. The survey is conducted by Finnish Institute for Health and Welfare (THL).


  • 18–34-year-old undergraduate students at universities of applied sciences and universities across Finland are invited to participate in the survey. The data collection is carried out with an online questionnaire. The survey is sent out to 12,000 randomly selected students based on data of the VIRTA student database.

  • The questionnaire is available in Finnish, Swedish and English.

  • In 2024, invitations will also be sent to those invited to participate in the KOTT 2021 survey who are still studying and who are enrolled in spring 2024.

  • Completing the questionnaire takes approximately 20 minutes. If necessary, you can take a break and continue later.

The Finnish Student Health and Wellbeing Survey (KOTT) has been reviewed by the THL working group on research ethics in 2020 and 2023.
