A granular analysis of longitudinal earnings data across UK universities has revealed stark disparities in lifetime wealth accumulation by degree subject and institution. The findings, drawn from the Longitudinal Education Outcomes (LEO) dataset, which tracks graduates up to a decade after graduation, underscore a persistent economic stratification within higher education. Medicine and economics degrees from the Russell Group universities consistently top the lifetime earnings ladder, with median earnings exceeding £70,000 by age 30. In contrast, creative arts and performing arts degrees from post-1992 institutions yield median earnings below £25,000, a gap that widens over a career.
The data, released by the Department for Education, show that subject choice matters more than institutional prestige. A graduate in economics from a non-Russell Group university still out-earns a history graduate from Oxford by age 35. The practical sciences, such as engineering and computer science, also perform strongly, particularly from universities with strong industry links like Imperial College London and the University of Manchester. The lifetime premium for a medicine degree is estimated at £1.5 million compared to a non-graduate, while for an arts degree the premium can be zero or negative when accounting for tuition fees and lost earnings.
Critics argue that such data reinforce a utilitarian view of education, ignoring the social and cultural value of the arts. However, the physical reality is that student debt in England averages £45,000, and graduates face a competitive labour market. For students making decisions about their futures, this data provides a clear signal: the economic return on higher education is highly variable. The Department for Education’s analysis, which controls for prior attainment and demographics, suggests that these differences are not solely due to selection effects.
What does this mean for the broader economy? A labour market increasingly polarised between high-paying knowledge sectors and low-paying service roles mirrors the stratification within universities. The concentration of high-earning graduates in London and the South East exacerbates regional inequality. As we navigate the energy transition and the rise of artificial intelligence, skills in STEM fields will be in even higher demand. The clear takeaway for policymakers is that investing in science and technology education delivers tangible economic dividends, while the arts humanities, though culturally essential, require careful funding models to justify their place in the portfolio of public investment.
The data also reveal a gender earnings gap within every subject, even after controlling for hours worked and occupation. Female graduates in medicine earn 15% less than male peers by age 35. This is not a problem universities can solve alone, but it highlights persistent structural biases in the labour market. The LEO data, now updated annually, should be required reading for every prospective student. It offers a sobering, evidence-based view of the financial landscape ahead. And that is a kind of clarity we urgently need in an era of tuition fees and graduate debt.
