BSc Programmes

Develop the analytical skills to quantify risk and guide strategic decision-making in an increasingly uncertain world. The BSc Actuarial Science (a three-year programme) provides rigorous training in mathematics and statistics, enriched with insights from finance, economics, and the social sciences. You will learn to apply actuarial and quantitative methods to pressing real-world issues, from managing financial risk to addressing global challenges such as ageing populations, pensions, economic instability, and climate resilience.

The BSc Actuarial Science programme is also offered as the BSc Actuarial Science (with a Placement Year) (a four-year programme), the only undergraduate degree at LSE to include a year of integrated industry experience before graduation. Taken between the second and final years, the placement is supported by the Department and LSE Careers and typically involves roles in leading insurance, consultancy, or financial firms. This professional experience enhances academic learning, develops workplace skills, and often leads to more attractive graduate job opportunities.

Our BSc Data Science course brings together the study of data science, machine learning, statistics and mathematics, with an emphasis on their real-world applications and impact on economics and society.

The programme has a strong mathematical focus and covers the practical skills required to become a data scientist. You will learn about the properties of data, how to extract insights from data, and how to effectively communicate the results. As you progress, you will build your understanding of classical and modern data analytics techniques, modelling, statistical machine learning, and artificial intelligence. You will also learn how to carry out typical workflows in data analytics, make inferences and become proficient in computer programming for data science.

Data scientists are in high demand in both the private and public sectors. By the time you graduate, you will possess all the practical skills and theoretical knowledge to progress to a career in areas such as banking, financial services and healthcare.

The BSc Economics and Data Science is a brand new degree which integrates the fields of economics and data science to provide a comprehensive understanding of economic principles, advanced data science methodologies, and the synergy between these two disciplines to address real-world problems.

The programme is designed for students who want to combine economic and econometrics theory with cutting-edge data analysis methods to gain insights.

The programme has a strong mathematical focus. You’ll learn about economics, econometrics, classical and modern data analysis tools, machine learning methods, and AI and become proficient in computer programming for data science.

This unique programme equips you with the conceptual frameworks and skills to analyse economic relationships, make data-driven decisions, and tackle real-world problems. It provides you with a programme of study designed for students who combine a strong analytical ability with the curiosity to apply rigorous economics and statistical methods to social science issues using data analysis.

Please note that this programme starts in September 2026.

The MSB programme is highly quantitative with a strong business-oriented component.

You will study an incredibly broad range of topics covering maths, statistics, economics and accounting in your first year. From the second year, you can tailor your studies to suit your interests and career aspirations by choosing one of the following pathways:

• applicable mathematics
• applied statistics
• actuarial science (courses are identical to those in the BSc Actuarial Science)
• economics
• finance
• accounting

You will be involved in practical projects, helping to develop your problem-solving and communication skills. Many of our students also complete internships in actuarial and financial firms or placement companies during their degree, providing invaluable workplace experience and providing the edge over other graduates.

Several courses also provide exemptions from professional examinations from the Institute of Actuaries.[insert link]

MSB graduates are highly employable, with recent alumni working in insurance, banking, accounting, statistics, the civil service, postgraduate study, and business consultancy.

Several courses also provide exemptions from professional examinations from the Institute of Actuaries.
