New Publication Reveals Postdoctoral Research Trends in South African Universities Over Two Decades

In the dynamic landscape of South African higher education, postdoctoral research fellows—often simply called postdocs—play a pivotal role as early-career researchers bridging the gap between doctoral studies and independent academic careers. A groundbreaking new publication titled "The Profile of Postdoctoral Research Fellows in South Africa: Trends over the Past Two Decades," authored by Heidi Prozesky and Francois van Schalkwyk from Stellenbosch University, offers the first comprehensive longitudinal analysis of these vital contributors.3031 Published in the South African Journal of Science in January 2024, this study draws on national datasets like the Higher Education Management Information System (HEMIS) and National Research Foundation (NRF) records to chart the evolution of postdocs from 2003 to 2019, revealing remarkable growth and shifting profiles.

This research arrives at a critical juncture, as South African universities grapple with expanding research outputs amid funding constraints and global talent competition. Postdocs, typically holding temporary positions lasting one to three years, dedicate over 90% of their time to research, fueling publications and innovations essential for institutional rankings and national development goals.29 For aspiring researchers eyeing opportunities in South Africa, understanding these trends is key to navigating the postdoctoral landscape.

Exploding Growth in Postdoc Numbers

The most striking revelation from the study is the explosive expansion of postdoctoral positions. In 2003, South African public universities hosted just 357 postdocs. By 2019, this figure had skyrocketed to 2,867—an eightfold increase over 16 years.32 This surge mirrors global patterns seen in countries like Finland and China, where postdoc numbers have similarly ballooned to bolster research capacity.

Recent updates from a 2025 national study extend this trajectory, showing 2,432 postdocs recorded in HEMIS data for 2022, though surveys suggest the true count nears 3,000 when accounting for underreporting.70 Growth accelerated post-2010, with a 143% rise from 2010 to 2019 alone, driven by policy pushes like Universities South Africa's 2013 Postdoctoral Policy, which standardized fellowships and emphasized their role in research intensification.

This expansion hasn't been uniform. Research-intensive institutions like the University of Cape Town (UCT), Stellenbosch University (SU), and University of Pretoria (UP) dominate, hosting the majority. For instance, UP had 303 postdocs in 2022, while ratios vary dramatically—up to three postdocs per academic staff member at the University of Johannesburg (UJ).

Demographic Shifts: Towards Greater Diversity

Demographics paint a picture of gradual transformation. Gender balance has stabilized with women comprising 41-44% of postdocs in recent years, lagging behind some global upward trends but reflecting preferential hiring of females into permanent roles.69 Racial composition shows progress: Black African representation doubled from 17.7% in 2016 to 32.3% in 2022, while White postdocs declined from 66.6% to 53.5%.70

Age profiles are skewing older, with the 41-50 cohort growing significantly, hinting at 'serial postdocs'—researchers holding multiple fellowships due to scarce permanent positions. About 25% in 2022 were serial, up from earlier years, signaling potential market saturation.69 This phenomenon underscores a broader casualisation of academic labor, where postdocs serve as flexible, low-cost research boosters.

For South African universities striving for equity post-apartheid, these shifts are encouraging yet incomplete. International postdocs, averaging 62% of the total, bring diversity but raise questions about local talent development. Top origins include Nigeria, Zimbabwe, and other African nations, comprising 78% of foreigners in 2022.

Field Distribution and Institutional Hotspots

• Natural sciences lead at 34-37%, followed by health sciences (16-19%) and social sciences (18-19%).
• Agriculture (11%) and economic/management sciences show variability, with humanities/arts facing funding squeezes.
• Top hosts: UCT, SU, Wits, UP, UJ, UFS—traditional 'Big Four' plus emerging players like UJ (457 in some counts).

These patterns align with South Africa's research strengths in astronomy, medical research, and biodiversity, bolstered by Centres of Excellence. However, uneven distribution exacerbates capacity gaps at historically disadvantaged institutions.

International Mobility and Its Challenges

Over 60% of postdocs are foreign-born, a stable trend since 2005, injecting global expertise but straining visa systems. Africans dominate inflows, yet 34% plan to emigrate—primarily to North America (50%) or Europe (18%)—citing better prospects, visa hurdles, and xenophobia.70

Department of Home Affairs delays (over eight weeks) and family visit restrictions compound issues, particularly for serial postdocs on short contracts. This brain circulation benefits SA temporarily but hinders long-term capacity building. Policymakers advocate streamlined visas and family allowances to retain talent.

Research Productivity and Output Surge

Postdocs are publication powerhouses: DHET-accredited articles rocketed from 30 in 2005 to 5,455 in 2022—an 18,150% increase.70 Averages hover at 1-3 papers per postdoc annually, with standouts in PLoS ONE and astronomy journals. They control key aspects like authorship (73%) and project planning (59%), though supervisors often demand senior authorship.

Despite 92% research time allocation, many juggle teaching (53%) and supervision (54% master's, 30% PhD), boosting institutional metrics but risking burnout. For career aspirants, this output is crucial—check tips for crafting an academic CV highlighting such achievements.

Funding Landscape: NRF and Beyond

The NRF funds ~27% (441 in 2022), with institutions covering 46%. Stipends range R200k-R299k annually for most (60%), deemed inadequate amid inflation—many call for R300k-R350k minimums with benefits like medical aid (only 13% access) and paid leave (17%).70 Quarterly payments plague 36%, exacerbating financial stress.

NRF's profile summary highlights this growth's implications for national R&D strategy.

Persistent Challenges and Precarity

Beneath the growth lies precarity: short contracts foster insecurity, with <10% transitioning to permanency. Serial postdocs (25%) reflect saturation, as PhD credential inflation demands extended training.69 Discrimination affects 16% (racial 21%, gender 9%), while 45% rate job prospects poor.

• Low benefits: maternity leave <10%, no savings for 78%.
• Workload overload: undesired grunt work, sabotage risks.
• Mental health toll: burnout from instability, isolation.

Postdocs feel like 'ice boys/girls'—exploited for cheap labor.16 Solutions include employee status recognition and standardized policies.

Implications for South African Higher Education

For universities, postdocs enhance rankings but risk exploitation backlash. Nationally, they advance Vision 2030 R&D targets, yet without reforms, talent flight looms. Stakeholders urge equity-focused funding and career pathways.

Prospective postdocs should target high-output fields and build networks. Resources like postdoctoral success strategies can help thrive amid challenges.

Future Outlook and Recommendations

Trends suggest plateauing growth post-COVID, with emphasis on quality over quantity. Recommendations from studies: longer contracts (min. 2 years), inflation-linked pay, visa reforms, and non-academic training.70
