  • How Many PhD Students Are There in the UK? The HESA Data (2026)

    How Many PhD Students Are There in the UK? The HESA Data (2026)

    The UK had 121,175 postgraduate research (PGR) students in 2024/25, of whom 110,455 were registered on research doctorates — the PhD and its equivalents — according to HESA’s Higher Education Student Statistics (SB273, released 27 January 2026). 55 per cent of postgraduate researchers are female.

    Those are the citable headline numbers for the UK’s doctoral population, and this page keeps them attached to the caveats that make them safe to quote. HESA — the higher education statistics agency, now part of Jisc — publishes the underlying bulletin annually; every figure below is from SB273 unless stated otherwise.

    The key figures

    PGR total, 2023/24 119,015 HESA SB273 series
    PGR total, 2024/25 121,175 HESA SB273 series

    What counts as a “PhD student” in these numbers?

    HESA’s category is postgraduate research — students whose programme is primarily research-based. Inside it, research doctorates (110,455 in 2024/25) cover the PhD/DPhil and doctorates of equivalent standing, while the remainder (10,635) covers research master’s degrees, the standalone MPhil and similar. Two boundary cases catch quoters out. Professional doctorates vary in classification depending on their research component, so “PhD students” and “doctoral candidates” are not perfectly interchangeable with the 110,455. And candidates registered MPhil pending upgrade are inside PGR throughout — the MPhil-to-PhD upgrade moves a student between rows, not into the population.

    What does the five-year shape tell you?

    The series is not a smooth line: roughly flat through the pandemic years, a spike to 123,660 in 2022/23 as delayed starts landed, a drop to 119,015, then a partial recovery to 121,175. Two implications for anyone citing it. First, pick your comparison year deliberately — “PGR numbers are falling” and “PGR numbers are rising” are both supportable by cherry-picking within this window, which is exactly why you should quote the series rather than a pair of points. Second, the volatility is concentrated in entry cohorts, which respond to funding rounds and international conditions faster than the stock of continuing students; the size of the funded pipeline — mapped in our stipends and studentship funding roundup — is the mechanism behind much of it.

    Students crossing a historic UK university quad
    About one UK student in twenty is a postgraduate researcher — a small population that produces most of the sector’s research output.

    Reading enrolment data critically

    Enrolment counts are a stock: everyone registered in the census snapshot, whether they started six weeks or six years ago. That has three consequences worth understanding before you build an argument on the numbers. A stock moves slowly — a dramatic fall in new starts takes years to show fully in the total, because continuing students dominate the count; so a flat total can conceal a shrinking pipeline, and the entrant figures elsewhere in the same bulletin are the earlier warning light. Multi-year programmes mechanically inflate stocks relative to one-year degrees — doctoral candidates each appear in three to five consecutive snapshots, a taught master’s student in one, so comparing PGR and PGT headcounts as if they measured annual demand misleads. And part-time and dormant registrations sit inside the same total as full-time candidates, which matters whenever you translate headcount into anything like research capacity. None of this is a flaw in the data; it is what enrolment data is. The errors come from quoting it as if it were something else.

    How international is the UK doctorate?

    Here is the caveat this page exists to enforce: SB273 does not break down domicile to the PGR level in its headline tables. A widely circulated figure — about 65 per cent of full-time postgraduates being non-EU internationally domiciled — describes all full-time postgraduates, taught and research combined, and must not be presented as a doctoral statistic. The honest sentence is that international recruitment matters substantially to UK doctoral education, and that anyone needing a precise PGR-level domicile split should pull it from HESA’s detailed tables for the year in question rather than quoting the postgraduate-wide number.

    What these numbers do not tell you

    Enrolment data measures the population, not its experience or outcomes. It says nothing about completion rates or times — which HESA does not publish as a PGR headline series — nothing about funding status (the same bulletin does not split self-funded from studentship-funded candidates), and nothing about examination outcomes, where the sector-wide dataset simply does not exist and the best available architecture data comes from institutional-documentation research covered in our viva outcomes analysis. Doctoral candidates are also invisible in undergraduate-facing statistics: degree classifications, for instance, end at the taught level — the classification data we compile on our undergraduate site has no doctoral column because a PhD is pass/fail.

    How to cite these figures

    Attribute to HESA, Higher Education Student Statistics: UK, 2024/25 (SB273, released 27 January 2026), and name the category precisely: “postgraduate research students” for the 121,175; “students on research doctorates” for the 110,455. Use academic years, not calendar years. If you are writing about “PhD students” loosely, the doctorate figure is the defensible anchor; if about research students broadly, the PGR total is. And resist the temptation to divide or combine HESA numbers into derived statistics the bulletin does not itself publish — every transformation you perform becomes your claim, not HESA’s.

    Three worked sentences you can adapt directly. For a thesis introduction: “In 2024/25 the UK’s postgraduate research population stood at 121,175, of whom 110,455 were registered on research doctorates (HESA, 2026).” For a trend claim: “PGR enrolments have fluctuated within a band of roughly 113,000–124,000 over the five years to 2024/25 (HESA, 2026).” For a composition claim: “Women make up 55 per cent of UK postgraduate researchers (HESA, 2026).” Each names the population, the year and the source — the three elements markers and reviewers check first.

    Why the population size matters to you

    If you are one of the 121,175, the number reframes two common doctoral feelings. The isolation is structural, not personal: you are one of a hundred-odd thousand people doing the least standardised degree in the system, most of whom also believe everyone else got an instruction manual. And the competition framing is mostly wrong: the relevant comparison group for your thesis is not 121,174 rivals but the handful of examiners who will read it against the criteria of your own institution. The work that moves you through that examination — a structured thesis, written steadily — is the same regardless of cohort size. Tesify keeps that structure and the writing moving — chapters, drafts and bibliography in one workspace, 100% written by you.

    Frequently asked questions

    How many PhD students are there in the UK?

    110,455 students were registered on research doctorates in 2024/25, within a total postgraduate research population of 121,175 (HESA SB273, January 2026).

    Is the UK doctoral population growing or shrinking?

    Neither cleanly: 114,405 (2020/21), 113,310, 123,660, 119,015, then 121,175 (2024/25). A spike, a correction, a partial recovery — quote the series, not two hand-picked points.

    What share of UK PhD students are women?

    55 per cent of postgraduate research students are female (HESA SB273, 2024/25).

    How many international PhD students does the UK have?

    SB273’s headline tables do not split domicile at the PGR level. The often-quoted ~65 per cent non-EU figure covers all full-time postgraduates including taught master’s students — citing it as a doctoral statistic is a misquote. Use HESA’s detailed tables for a PGR-level split.

    What is the difference between PGR and PhD in the statistics?

    PGR (postgraduate research) is the umbrella: research doctorates (110,455) plus research master’s, MPhil and similar (10,635). All PhDs are PGR; not all PGR students are PhD candidates.

    How many PhDs are awarded in the UK each year?

    That is a qualifications-obtained figure, published separately in HESA’s qualifications tables rather than the enrolment series quoted here. Take it from the same bulletin’s qualifications section for the year you need.

    What proportion of UK students are doctoral candidates?

    Postgraduate researchers are a small minority of the student body — on the order of one in twenty — which is why PGR-specific policy and data so often lag the undergraduate-focused headlines.

    Does HESA publish PhD completion rates?

    Not as a routine headline series. Completion and submission-time analyses come from funders and one-off studies; be suspicious of any precise “UK PhD completion rate” quoted without a named source and year.

    Where does HESA’s data come from?

    From statutory data returns made by higher education providers each year, compiled by HESA (part of Jisc) — it is administrative data covering the sector, not a survey estimate.

    Where do I find the numbers for one university?

    HESA publishes provider-level open data alongside the bulletin — enrolments by level of study per institution — and universities repeat headline counts in annual reports. For anything finer, the institution’s planning office is the source.

  • What Is the REF and Does It Affect PhD Students? (REF 2029, Explained for Researchers)

    What Is the REF and Does It Affect PhD Students? (REF 2029, Explained for Researchers)

    The Research Excellence Framework (REF) is the UK’s periodic assessment of research quality in universities, run jointly by the four higher education funding bodies — Research England, the Scottish Funding Council, Medr in Wales and the Department for the Economy in Northern Ireland — to inform the allocation of research funding. The next exercise is REF 2029, with submission expected in autumn 2028 and results in December 2029. It does not examine you, and your thesis cannot be submitted to it — but it shapes the environment your doctorate happens in more than any other single policy instrument.

    That double answer — not about you, yet everywhere around you — is why doctoral researchers keep asking about the REF and keep getting confusing answers. Here is the machinery, and then the parts that actually touch a PhD.

    What does the REF assess?

    Universities make submissions in disciplinary units of assessment, and expert panels grade three elements: research outputs (papers, monographs, other published work), impact beyond academia, and the environment in which research happens — with the familiar star ratings from unclassified to 4* (“world-leading”). The published results feed the funding bodies’ allocation of annual research funding and drive the league-table narratives that follow. For REF 2029 the exercise has also been evolving under the Future Research Assessment Programme, including a People, Culture and Environment element that has been piloted — a signal that how institutions treat their research communities, doctoral researchers included, is moving closer to the centre of assessment.

    Where did it come from?

    Periodic research assessment has been part of UK academic life for decades: a series of Research Assessment Exercises through the late twentieth century gave way to the renamed Research Excellence Framework, whose previous full exercises ran in 2014 and 2021. Each iteration has redrawn some element — impact case studies arriving, output portability changing, culture and environment rising — which is worth knowing for one practical reason: advice calibrated to a previous REF is often quietly wrong about the next one. When a colleague states a REF rule with confidence, ask which exercise it belongs to.

    Can my PhD thesis or my papers be submitted to REF 2029?

    Your thesis, no. The eligibility rules for REF 2029 exclude outputs whose only substantive link to the submitting institution is through its postgraduate research students — which encompasses PhD theses themselves. Your published papers are a different matter with a precise boundary: work you co-author with staff members can be submitted through those staff, because the substantive link runs through them; work authored only by you as a PGR student is not returnable by the institution. If you are also employed by the university on an academic contract — common toward the end of a doctorate — your status changes with the contract, not the candidature.

    The practical upshot: publishing during your PhD remains valuable for every reason that mattered before — the examination, the job market, the contribution itself, as covered in how to publish a paper from your thesis — and co-authored work may additionally carry REF value for your supervisors’ unit. That asymmetry explains a certain pattern of departmental enthusiasm for co-authored outputs, which you are entitled to notice and negotiate around when authorship is discussed.

    The REF assesses institutions, not candidates — but its incentives flow downhill into supervision, hiring and funding.

    Where is REF 2029 in its timetable right now?

    The exercise is in the late stages of policy development, and it has not been a smooth road: criteria-setting was paused in September 2025 and resumed in December 2025 without a formal consultation, and in July 2026 the REF team launched a sector survey on the remaining policy areas. The working dates remain submission in autumn 2028 with results in December 2029, and machinery is being bolted down — including arrangements for institutions to amend REF-specific fields in the 2025/26 staff data collection. For a doctoral researcher the detail matters less than the rhythm: universities are now entering the preparation phase in which REF considerations visibly steer hiring, publication strategy and internal reviews, and will stay in it for the rest of your candidature if you are mid-doctorate now.

    How does the REF actually affect a PhD student?

    Through five channels, all indirect and all real. Funding: REF results inform the block research funding that helps sustain doctoral training and research environments — the same institutional research economy mapped in our stipends and funding roundup. Supervision: your supervisors carry REF expectations for outputs and impact, which shapes the time they have and the projects they favour; understanding that pressure makes their behaviour more legible and more negotiable. The environment element: doctoral training, completion support and research culture feature in what institutions must evidence — one of the few places where your experience as a PGR student is, in aggregate, part of what gets assessed, and the piloted People, Culture and Environment element pushes further in that direction. The job market: if you are aiming at UK academia, you will be hired by departments thinking about their next submission, and a publication record that would grade well is a currency whether or not anyone says so aloud in the interview. And research culture at large: what the REF rewards, universities do more of — the exercise is the sector’s incentive architecture, which is exactly why its reform debates run so hot.

    Three REF myths that circulate in PGR offices

    “My thesis needs to be 4*.” No — star ratings attach to institutional submissions, not doctorates; your thesis is examined against your university’s doctoral criteria, full stop. “I must publish four papers before the viva because of the REF.” No — the exercise sets no requirement on candidates, and UK doctorates do not generally require publications to pass; publication strategy is about your examination and career, not the institution’s return. “The REF is why my supervisor is too busy.” Sometimes partly true, never the whole truth — but the sympathetic version of the insight is useful: supervisors are being assessed too, and the candidate who understands the pressures on a supervisory team gets more out of it.

    What should you actually do about it?

    Less than the anxiety suggests, more than nothing. Do not choose your thesis topic for REF-legibility — the doctorate is examined on its contribution to knowledge, not its star potential, and chasing assessability corrupts the research question. Do publish strategically rather than reactively: quality over count is both the REF’s official doctrine and good career sense. Do ask, when weighing academic posts, how the department treats its research community — the environment evidence cuts both ways, and a department that resources its people well is telling you something the league table does not. And keep the thesis moving while the sector argues about assessment: the exercise will change shape again; your submission date will not. Tesify keeps the chapters, drafts and bibliography structured while you do the research — 100% written by you.

    Frequently asked questions

    What does REF stand for?

    Research Excellence Framework — the UK-wide assessment of university research quality, run roughly every seven years by the four higher education funding bodies. Its predecessors ran under the RAE (Research Assessment Exercise) name.

    When is the next REF?

    REF 2029: submission is expected in autumn 2028 with results published in December 2029. Policy details were still being finalised through 2026, including via a sector survey launched that July.

    Who runs the REF?

    Research England, the Scottish Funding Council, Medr (the Welsh tertiary education body) and the Department for the Economy in Northern Ireland, acting jointly.

    Can a PhD thesis be submitted to the REF?

    No. REF 2029’s rules make outputs ineligible where their only substantive link to the institution is via postgraduate research students — which covers PhD theses.

    Do papers I publish during my PhD count for the REF?

    Not through you as a PGR student — but a paper co-authored with staff can be returned through those staff members. Your sole-authored work becomes returnable if and when you hold an eligible staff position.

    Does the REF examine or rank individual researchers?

    No — it assesses institutional submissions by discipline. Individuals feel it through their department’s preparation, not through any personal REF grade; there is no such thing.

    What are REF star ratings?

    Panels grade submitted elements on a scale to 4*, denoting world-leading quality, with the profile of grades across outputs, impact and environment forming the published result that informs funding.

    What is the People, Culture and Environment element?

    A developing component of REF 2029, piloted during the preparation phase, that broadens the old environment assessment toward how institutions support research culture and careers — the element with the most direct doctoral relevance.

    Should I mention the REF in academic job applications?

    Indirectly: present your strongest publications and their quality markers rather than REF vocabulary. Panels hiring toward a submission can do the mapping themselves — your job is to give them material worth mapping.

    Where do I read the official REF 2029 rules?

    The exercise publishes its guidance, timetable and decisions on the official REF 2029 website — the source to prefer over commentary, including this page, for anything you plan to act on.
