The world has witnessed an unprecedented expansion in higher education over the past two decades, with university enrolment more than doubling globally from around 100 million students in 2000 to 269 million in 2024.
Yet, behind the celebration of mass access to universities lies a stubborn and widening reality that higher education remains deeply unequal depending on where students live, how much they earn, their gender, or whether they have been displaced by conflict, according to a UNESCO study released earlier this month.
The study describes a world in which tertiary education has become increasingly essential for economic survival and social mobility but remains inaccessible for millions.
The report paints a picture of dramatic growth driven by expanding middle classes, digital learning opportunities, globalisation and the increasing demand for skilled labour. Universities have multiplied, international student mobility has surged, and women now outnumber men in higher education globally, says the report.
But the data also reveal that access to higher education is increasingly divided along geographic and socio-economic lines.
In Western Europe and North America, about 80% of young people are enrolled in higher education institutions. In sub-Saharan Africa, however, only 9% are enrolled. Latin America and the Caribbean stand at 59%, while South and West Asia remain at about 30%.
The disparity reflects a broader global imbalance in wealth, infrastructure and state investment in education. While universities in wealthier countries increasingly market themselves as global hubs for research and innovation, institutions in poorer regions often struggle with overcrowding, underfunding and shortages of lecturers and facilities.
The report found that Africa’s universities are expanding faster than ever, but millions of young people across the continent are still being left behind.
The study shows that while higher education enrolment worldwide has surged from about 100 million students in 2000 to 269 million in 2024, sub-Saharan Africa remains the region with the lowest participation rates. Only 9% of young people of university-going age in the region are enrolled in higher education, compared with 80% in Western Europe and North America.
UNESCO warns that the rapid global expansion of universities masks “stark regional disparities”, with African students facing barriers linked to poverty, limited infrastructure, underfunding and unequal access between urban and rural communities. Completion rates also remain low, meaning that many students who enter tertiary institutions do not finish their studies.
The report highlights gender inequality as another major challenge. Although women now outnumber men in higher education globally, sub-Saharan Africa is the only region where gender parity has not yet been achieved.
UNESCO found that many African women continue to face obstacles such as early marriage, financial exclusion and cultural expectations that limit their participation in universities and colleges.
At the same time, Africa’s youthful population is placing mounting pressure on governments to expand access. The continent is expected to account for a large share of the world’s population growth over the coming decades, increasing demand for universities, technical colleges and digital learning systems.
Analysts say this creates both an opportunity and a risk: without major investment, millions of young Africans could remain excluded from advanced education and the economic opportunities it brings.
UNESCO noted that public financing for higher education remains inadequate in many countries. Globally, governments spend an average of just 0.8% of GDP on higher education, and fiscal pressures are straining universities further. The organisation called for “innovative financing models” to ensure quality and inclusion.
Despite these challenges, the report points to signs of progress in parts of Africa. Countries such as South Africa, Mauritius and others have introduced targeted fee reductions or support programmes for disadvantaged students.
The findings underscore a growing divide: while higher education is becoming a defining feature of economic development globally, much of Africa is still struggling to ensure that expansion translates into equitable access and meaningful opportunity.
The report warns that the rapid growth in student numbers has placed enormous pressure on higher education systems worldwide. Completion rates have not kept pace with enrolment growth.
Although more students are entering universities, many are failing to graduate. The global graduation ratio rose only modestly from 22% in 2013 to 27% in 2024.
This raises questions about whether expanding access alone is enough.
For many students in developing countries, entering university is only the first hurdle. Affording tuition, housing, transport and digital connectivity remains difficult, particularly as governments reduce public spending and universities increasingly depend on private financing models.
UNESCO notes that only one-third of countries worldwide legally guarantee tuition-free public higher education. In many countries, students rely heavily on loans, scholarships or family support to complete their studies.
The growth of private universities has also transformed the sector. Private institutions now account for roughly one-third of global enrolment, with some countries such as Brazil, Chile, Japan and South Korea seeing four out of every five students attending private institutions.
Critics argue that the privatisation of higher education risks deepening inequality by turning university access into a commodity available mainly to those who can afford it.
The expansion of higher education has also exposed a paradox of globalisation. International student mobility has tripled since 2000, with nearly 7.3 million students studying abroad in 2023.
However, this opportunity is concentrated among a small minority of students globally. Only about 3% of the world’s higher education students study abroad, the study found.
Moreover, the international education market remains dominated by a handful of wealthy nations. The United States, United Kingdom, Australia, Germany, Canada, Russia and France host roughly half of all international students worldwide.
For students from low-income countries, studying abroad often remains financially unattainable, despite scholarship programmes and exchange opportunities. Visa restrictions, rising living costs and political instability in host countries have added further barriers in recent years.
Gender equality in higher education has improved significantly, but the report shows that equality remains uneven and incomplete.
Globally, women now outnumber men in tertiary education, with 114 women enrolled for every 100 men in 2024. Regions such as Central and Southern Asia have made major gains since 2000.
Yet, women remain underrepresented at the doctoral level and occupy only about one-quarter of senior academic leadership positions worldwide. In sub-Saharan Africa, gender parity in enrolment has still not been achieved.
The findings suggest that increasing access does not automatically dismantle structural barriers related to leadership, income inequality and social expectations.
The report also highlights the challenges facing refugees and displaced populations. Despite an increase in refugee participation in higher education from 1% in 2019 to 9% in 2025, millions continue to face obstacles linked to missing academic records, language barriers and financial hardship.
UNESCO has attempted to address some of these problems through initiatives such as the Qualifications Passport, which helps refugees verify academic credentials when official documentation is unavailable. The programme is currently operating in countries including Kenya, Uganda, Zambia and Zimbabwe.
Analysts say the report ultimately reflects a broader global contradiction. Education is increasingly recognised as essential for economic participation in a technology-driven world, yet the systems meant to deliver it remain profoundly unequal.
Artificial intelligence and digital technologies are reshaping universities at a rapid pace, but UNESCO found that only one in five universities had a formal AI policy in 2025.
At the same time, governments are struggling to maintain funding. Global public investment in higher education averages only about 0.8% of GDP, even as demand continues to surge.
The expansion of higher education may therefore represent both a success story and a warning sign. More people than ever before are entering universities, crossing borders to study and accessing opportunities previously reserved for elites. Yet the benefits of this educational revolution remain unevenly distributed.
For students in wealthy countries, higher education increasingly functions as a gateway into the global knowledge economy. For millions elsewhere, university remains an aspiration constrained by poverty, geography and unequal opportunity.
The challenge for governments and institutions in the coming decades may not simply be enrolling more students, but ensuring that higher education becomes genuinely inclusive, affordable and capable of delivering meaningful outcomes for all.
