The one-line summary

UNESCO-recognised international observance on September 8. Established in 1965. International category, minor tier.

Origin

International Literacy Day was established by UNESCO at the 14th session of its General Conference in 1966. The date of September 8 was chosen to commemorate the inauguration of the World Congress of Ministers of Education on the eradication of illiteracy, held in Tehran in 1965. The first International Literacy Day was observed on September 8, 1966.

UNESCO's literacy work has evolved over six decades, with successive initiatives including the Experimental World Literacy Programme (1967), the Literacy Initiative for Transformation (2012), and the Literacy and Skills Development Programme. UNESCO continues to coordinate global literacy efforts through its Institute for Lifelong Learning (UIL) based in Hamburg.

Literacy and digital skills

UNESCO has expanded the definition of literacy to include digital literacy, media literacy, and financial literacy. International Literacy Day promotion increasingly focuses on digital skills, with the 2024-2025 theme "Literacy in the Digital Era" highlighting the role of literacy in navigating online information environments.

UNESCO Institute for Lifelong Learning (UIL) in Hamburg supports member states with literacy policy and capacity building. UIL publishes the annual Global Education Monitoring Report and supports the UNESCO Global Network of Learning Cities, which includes over 200 cities committed to lifelong learning.

Literacy by the numbers

UNESCO Institute for Statistics (UIS) reports that global adult literacy rates have risen from 81% in 1990 to 87% in 2024. Despite progress, 773 million adults still lack basic literacy skills, two-thirds of whom are women. International Literacy Day promotion highlights the gender gap in literacy, particularly in South Asia and sub-Saharan Africa.

Youth literacy rates are higher - global youth literacy stands at approximately 92% - but progress has slowed in recent years. The 2024-2025 theme "Literacy in the Digital Era" highlights the need for new metrics that capture not just reading and writing but also digital navigation, critical evaluation of information, and creative expression through digital media.

Literacy and gender statistics

The gender gap in literacy persists in many regions. UNESCO data shows that two-thirds of the world’s 773 million illiterate adults are women, with the largest gaps in South Asia, the Arab States, and sub-Saharan Africa. International Literacy Day promotion frequently highlights girls’ education as a pathway to closing the gap.

The UNESCO Global Education Monitoring Report tracks progress on gender parity in education under SDG 4. Recent reports have noted that while primary school enrolment has reached gender parity globally, completion rates and learning outcomes still show significant gender gaps in many countries.

Literacy and public health

Literacy is closely linked to public health outcomes. UNESCO’s 2024-2025 theme "Literacy in the Digital Era" highlighted the role of digital literacy in navigating health information, particularly during public health emergencies. Health literacy programmes have become a focus of UNESCO’s literacy work.

Research consistently shows that low literacy is associated with poorer health outcomes, lower use of preventive health services, and reduced ability to manage chronic conditions. World Literacy Day promotion increasingly highlights literacy as a social determinant of health and a key lever for public health equity.

Literacy and employment

Literacy is strongly linked to employment outcomes. UNESCO data shows that illiterate adults are far more likely to be unemployed, underemployed, or trapped in informal-sector work. International Literacy Day promotion frequently highlights literacy as a key enabler of economic participation, social mobility, and gender equality.

Workplace literacy programmes have expanded in many countries, with employers investing in basic and digital literacy training for their workforces. UNESCO’s Global Network of Learning Cities supports workplace literacy through partnerships with employers, trade unions, and vocational training providers.

Literacy in conflict and crisis

Literacy is critical in conflict and humanitarian crisis settings. UNESCO supports emergency education and literacy programmes in refugee camps, conflict zones, and post-disaster settings, working with UNHCR, UNICEF, and partner NGOs. International Literacy Day promotion has increasingly highlighted these programmes as part of broader humanitarian response.

Research from UNESCO and the Inter-Press Council has documented how literacy provides protection in crisis settings - enabling people to navigate aid systems, access health information, and participate in community decision-making. International Literacy Day events frequently highlight the role of literacy in resilience and recovery.
