The transition from childhood to adulthood is an important, fascinating period of life. Young people in their teens and early 20s need particular support and special services, particularly those who may be marginalised. Pulling together age specific data about this age group can lead to a better understanding of their health needs, and can help us to provide more appropriate, youth-friendly health services.

In this comprehensive data review focusing specifically on the health of 10-24 year olds in the UK, we look at living circumstances, education and employment, information about health behaviours and lifestyle, sexual health, mental health, physical health and longterm conditions, and use of health care services. Our final chapter focuses on inequalities in health, highlighting groups of young people whose health may need extra resources and investment.
