Course overview
Population Health Sciences gives you a broad and deep understanding of how health and disease are measured and analysed, incorporating research methods, demography, infectious and non-communicable disease and life course epidemiology.
World-leading researchers immerse you in the social, economic and demographic distribution of health and disease, and show you how to analyse big data to address health inequalities. You are provided with the opportunity to develop transferable skills including interpretation and communication of complex ideas. These are highly sought after by graduate employers, from international NGOs to start-ups and will also prepare you for postgraduate study should you pursue this.
In Years 1 and 2, you gain a thorough understanding of how health and disease are measured and analysed, incorporating research methods, demography, infectious and non-communicable disease and life course epidemiology. You receive applied data analysis training in all years, bringing UCL's unparalleled data access and understanding of theory together in a hands-on learning environment. As you progress through the degree, you are provided with increased opportunity for specialisation in population health.
What this course will give you
UCL is ranked 3rd in the world for public health (ShanghaiRankings 2024), is among the top ten in the QS World University Rankings 2025 and is winner of The Times and Sunday Times University of the Year 2024.
Our students are closely integrated into our community through research-embedded teaching. As a student within the Faculty of Population Health Sciences, you will discover the cutting-edge research and innovations that are delivering real-world benefits.
You will learn new skills in high-level data analysis and research methods, as well as highly sought-after skills for the workplace such as problem-solving, collaboration and presenting.
You also have the opportunity to join the UCL Population Health Sciences Society the Faculty of Population Health’s student-led society that aims to build community and support systems for those studying or who are passionate about population health, improving health outcomes and reducing inequalities.
Our central London location gives our students access not only to the best in entertainment and nightlife, but also to cultural and academic resources. We are close to, and have teaching and research links with, numerous leading hospitals, museums, galleries, libraries and professional bodies.
The programme offers an optional study abroad year. Those who want to study abroad will apply for a place at a selection of international universities in their second year. If their application is successful, students will then go on to study abroad in their third year. UCL has long-established links with universities in Europe, Asia-Pacific and North America. The universities available as options for study abroad may vary year on year.
Teaching and learning
In each year of your degree you will take a number of individual modules, normally valued at 15 or 30 credits, adding up to a total of 120 credits for the year. Modules are assessed in the academic year in which they are taken. The balance of compulsory and optional modules varies from programme to programme and year to year. A 30-credit module is considered equivalent to 15 credits in the European Credit Transfer System (ECTS).
Modules
Please note that the list of modules given here is indicative. This information is published a long time in advance of enrolment and module content and availability is subject to change. Modules that are in use for the current academic year are linked for further information. Where no link is present, further information is not yet available.

In Year 1, you gain a broad knowledge of population health sciences, including research methods, social determinants of health and modules on social data science.
In Year 2, core modules deepen your knowledge and advance your data science skills. In addition, you begin to shape your degree to your interests, with optional modules from epidemiology and health care, political science, geography, social sciences, and global health.
In Year 3, alongside your advanced data science modules, you will also have optional modules to personalise your degree within population health sciences. One quarter of the final year marks come from the dissertation, a piece of original research, supervised by research and teaching staff within the department. This is your chance to showcase your abilities and focus on an issue that you care about.
Please note the following module information:- A Life Course Approach to Health is a compulsory module for Data Science students in Year 2.
- Perspectives on Global Health is an optional module for Data Science students in Year 2.
Compulsory modules
Your learning
Teaching will be delivered through lectures, problem-based seminars, practical computer classes, group work and through UCL's virtual learning environment. You have access to online learning facilities where you can interact with world-leading researchers and fellow students.
You would be expected to spend 40 hours a week in full-time study, which is made up of a mixture of contact hours and self-directed study. In a typical week, this would be approximately 8 – 10 contact hours per teaching week in a mixture of lectures, seminars, and tutorials and 30 – 35 hours of self-directed study, although this ratio will vary depending on which year you are in and which optional modules you select.
Assessment
Assessment takes place via various methods including examinations, practical exercises, essays, individual and group presentations and a dissertation in the final year of study. The weight given to each method will vary to ensure manageable workloads throughout the programme. Modules are assessed in the academic year in which they are taken.
