This website has been produced by the Association for Young People’s Health (AYPH), a UK based charity. AYPH is the independent voice for young people’s health. We believe that young people have a right to good health and high quality accessible healthcare. You can find out more about our work on our main website

This site is our data portal, where we have collected together statistics about youth health and information about how to use them in your work. One of AYPH’s central aims is to promote evidence-based practice by making research findings more accessible. The first edition of the website was constructed in the autumn of 2021. Each page indicates when the data were last updated. Although we will be making minor amends to it, a major revision is not planned until 2023.
