KEY DATA ON YOUNG PEOPLE 2021

The Key Data series has been running since 1997, providing nearly 25 years of information about young people’s lives. Previous editions have been hard copies or on-line PDFs; since 2021 we have presented it as a website.

Key Data collates publicly available data, extracting what we can find that is directly relevant to the 10-25 age group. The information is organised by topic. Click on different themes to get an overview, key findings and links to more information. You can also use the search function to find information on different topics.

We’re very interested in what you think of this as a resource, or any information you might have about additional data sources that might be relevant. Please do email us at any time with comments, suggestions and feedback, or complete our feedback survey.

To accompany the website and to highlight the main themes and ‘take home’ messages we have prepared an ‘Overview and Policy Implications’, which is downloadable as a PDF.
