Sex under the age of 25
Sex under the age of 25 is the largest national survey on sex and relationships among young people aged 12 to 25.
National survey
Sex under the age of 25 is conducted once every 5 years. We do this to measure trends and developments in the health and lifestyle of young people. Soa Aids Nederland and Rutgers conduct this survey on behalf of the Ministry of Health, Welfare and Sport and the RIVM (National Institute for Public Health and the Environment). We do this together with GGDs throughout the Netherlands and the Central Bureau for Statistics (CBS).
Around 10,000 young people were invited to take part in the national survey between October 2022 and February 2023:
- Young people aged 12 to 16.5 complete the online questionnaire at school.
- Young people aged between 16.5 and 24 will receive an invitation from the Central Bureau of Statistics to take part.
People aged 25 and over received an invitation to participate in the Monitor Sexual Health in the Netherlands.
The survey provides important insights into young people's sexual health, lifestyle and information needs. These figures underpin prevention, care, policy and information choices. The previous 2017 survey provided these recommendations.
