Education and Development
This lesson examines education as a driver of human development, exploring global patterns in educational access and attainment, the links between education and health, the challenges of brain drain, and the role of education in the MDGs and SDGs. It addresses the Edexcel Enquiry Question: "What is human development and how does it vary globally?" by focusing on the education dimension.
Education is often described as the single most powerful force for reducing poverty and improving health. The returns on education investment are enormous — for individuals, communities and nations. Yet approximately 250 million children and adolescents worldwide are still out of school, and hundreds of millions more attend school but learn very little. Understanding why this matters — and why education is both an indicator of development and a driver of it — is essential for this topic.
Education as a Driver of Development
The Economic Returns
Education boosts development through multiple channels:
- Human capital: Education increases the productivity and earning capacity of individuals. Each additional year of schooling increases an individual's earnings by approximately 8–13% on average globally (World Bank estimates). Over a lifetime, the difference between no education and 12 years of schooling translates into dramatically higher lifetime earnings and consumption.
- Innovation and technology: Educated populations are better able to adopt, adapt and create new technologies. Countries with higher educational attainment grow faster and are more economically competitive. South Korea's transformation from a low-income country in the 1960s (GDP per capita similar to Ghana) to a high-income OECD member today was driven substantially by massive investment in education.
- Governance: Education promotes democratic participation, critical thinking and accountability, contributing to better governance and reduced corruption. Research consistently shows that more educated populations are more likely to demand transparency, hold leaders accountable and participate in civic life.
- Social cohesion: Education can reduce inequality, promote tolerance and build social capital — though it can also reinforce existing inequalities if access is unequal. Schools are sites where social norms are shaped, and inclusive education can promote gender equality, ethnic tolerance and disability rights.
The Health Returns
The links between education and health are among the strongest relationships in development:
- Maternal education: A mother's education level is one of the most powerful predictors of child survival. Children of mothers with secondary education are approximately 50% less likely to die before age five compared to children of mothers with no education. This operates through multiple mechanisms: educated mothers have better health knowledge, are more likely to seek prenatal care, are more likely to vaccinate their children, and have greater economic resources and decision-making power within the household.
- Family planning: Educated women tend to have fewer children, spaced further apart, and are more likely to use modern contraception. The total fertility rate in sub-Saharan Africa is approximately 4.6 overall, but only 2.8 among women with secondary education. This has profound implications for maternal health, child health and economic development.
- Health knowledge: Educated individuals are more likely to understand hygiene, nutrition, vaccination, and disease prevention, and more likely to seek medical care when needed. They are also better able to navigate healthcare systems, understand medical advice and advocate for their health needs.
- HIV prevention: In sub-Saharan Africa, young people who complete secondary education are significantly less likely to contract HIV than those who do not — education provides knowledge about transmission, negotiation skills for safer sex, and economic alternatives to transactional sex.
- Mental health: Education is associated with better mental health outcomes, greater resilience and stronger social networks — all of which are protective factors.
Exam Tip: The education–health link is a key synoptic connection in the Edexcel specification. When discussing either education or health, always cross-reference the other to demonstrate your understanding of how development dimensions are interconnected.
Global Patterns of Educational Access
Literacy Rates
Adult literacy (the percentage of the population aged 15+ who can read and write) varies enormously:
| Region/Country | Adult Literacy Rate (2023 est.) | Notes |
|---|
| Global average | 87% | Significant progress from 68% in 1979 |
| Europe | 99%+ | Near-universal; most variation in elderly populations |
| East Asia | 97% | China's mass literacy campaigns (1950s–1980s) were transformative |
| Latin America | 94% | Improving but indigenous and Afro-descendant communities lag |
| South Asia | 73% | India at 77%, but wide gender and regional gaps |
| Sub-Saharan Africa | 65% | Lowest regional rate; wide variation between countries |
| Niger | 37% | World's lowest national literacy rate |
| Chad | 26% | Among the lowest globally; under 15% for women |
Gender gap in literacy: Globally, approximately two-thirds of the world's 773 million illiterate adults are women. The gender gap is most pronounced in South Asia and sub-Saharan Africa. In Afghanistan, male literacy is approximately 55% while female literacy is approximately 30%. In Mali, female adult literacy is only 26% compared to male literacy of 46%. This gender gap reflects the systematic underinvestment in girls' education in many LICs, driven by cultural norms, poverty (when resources are scarce, families often prioritise boys' education), early marriage and safety concerns.
Primary and Secondary Enrolment
Primary enrolment has improved dramatically — the global net primary enrolment rate reached approximately 89% in 2023, up from 83% in 2000. The number of out-of-school children of primary age fell from 100 million in 2000 to approximately 64 million in 2023. The regions with the highest numbers of out-of-school children are sub-Saharan Africa (approximately 33 million) and South Asia (approximately 11 million).
However, secondary enrolment remains a major challenge. In sub-Saharan Africa, the gross secondary enrolment rate is approximately 50%, compared to over 100% (indicating over-age students) in most HICs. The secondary completion rate for girls in sub-Saharan Africa is approximately 38% — meaning over 60% of girls who start secondary school do not complete it. The transition from primary to secondary is where most educational attrition occurs, particularly for girls.
Barriers to educational access:
- Poverty: Families cannot afford school fees, uniforms, books and transport. Children are needed for labour — approximately 160 million children aged 5–17 are engaged in child labour. The opportunity cost of education is high for poor families.
- Distance: In rural areas, the nearest school may be many kilometres away, particularly at secondary level. In rural Tanzania, the average distance to the nearest secondary school is approximately 24 km.
- Gender: Cultural norms, early marriage, pregnancy and safety concerns disproportionately affect girls' education. In many contexts, menstruation is a barrier — lack of sanitary facilities, menstrual products and privacy causes girls to miss school or drop out.
- Conflict: Approximately 222 million school-age children are affected by conflict (2023). Schools are attacked, teachers flee and education budgets are diverted to military spending. In northern Nigeria, Boko Haram — whose name translates loosely as "Western education is forbidden" — has systematically attacked schools, kidnapping students (notably the 276 Chibok girls abducted in 2014) and destroying over 1,000 schools.
- Disability: Children with disabilities in LICs face extreme barriers to educational access — lack of accessible facilities, trained teachers and assistive technology. An estimated 32 million children with disabilities are out of school globally.
- Language: In many post-colonial countries, education is delivered in the colonial language (English, French, Portuguese) rather than local languages, creating a barrier for children from non-urban backgrounds. Children learn more effectively in their mother tongue, particularly in the early years.
The Learning Crisis
Access to education is necessary but not sufficient. The World Bank's 2018 World Development Report warned of a global "learning crisis" — millions of children attend school but learn very little:
- In sub-Saharan Africa, approximately 86% of children cannot read proficiently by age 10 (this is the "learning poverty" indicator).
- In South Asia, the figure is approximately 58%.
- The World Bank estimates that 53% of children in LICs and MICs cannot read and understand a simple story by the end of primary school.
- A survey of grade 3 students in Uganda found that 50% could not read a single word of a simple sentence.
