UK Biobank is the world’s most comprehensive dataset of biological, health and lifestyle information.
After personal identifying information is removed from our data on 500,000 participants, scientists from across the world can apply to use it for research that is in the public interest.
What makes us special
UK Biobank is the world’s most detailed study for tracking the long-term health of people as they age.
The combination of these four aspects sets our dataset apart from other similar initiatives.
Where the data come from
Our participants

Since 2006, we have collected an unprecedented amount of biological and medical data on half a million people, aged between 40 and 69 years old and living in the UK when they joined.
Studies like ours need to be this large to give the best chance of understanding the causes of disease and how they progress. Only a small proportion of the participants will go on to develop a particular disease and that group needs to be large enough to study how genes, environments and life experiences affect the disease.
With their consent, our participants continue to provide detailed information about their lifestyle via online questionnaires, as well as data from their health records and related information, to provide a deeper understanding of how diseases develop.
Enhancements

Some of our participants have also:
- returned for body scans with medical imaging equipment
- provided additional blood, urine and saliva samples
- worn physical activity monitors
- worn heart health monitors
- completed online questionnaires
In collaboration with our funders and a range of technology and pharmaceutical companies, we have also transformed our participants’ biological samples into data including:
- whole genome sequences for all our participants
- measures of levels of proteins, hormones and metabolites in our participants’ blood
As technology develops, we’ll be able to unlock even more data from the biological samples that we store.
