International Literacy Day 2026: 60 Years On, 739 Million Adults Still Lack Basic Skills

International Literacy Day, proclaimed by UNESCO in 1966 and first observed on September 8, 1967, marks its 60th anniversary today, September 8, 2026. The global observance, themed “Literacy for people, the planet and prosperity,” is being held in Mexico on September 8 and 9, as announced by UNESCO. This annual event serves as a crucial reminder to policymakers, practitioners, and the public about the fundamental importance of literacy in fostering more literate, just, peaceful, and sustainable societies. Despite considerable advancements over the past six decades, a substantial global population continues to face barriers to basic education.

International Literacy Day 2026: Global Literacy Landscape

The global adult literacy rate currently stands at approximately 88%, a significant increase from 56% in 1950 and 70% in 1980, based on what data from UNESCO and the Unesco Institute for Statistics (UIS). In 2000, the adult literacy rate was about 81%, demonstrating consistent upward trends. However, a stark reality persists: at least 739 million adults worldwide still lack basic literacy skills, with almost two-thirds of this population being women.

Youth literacy, for those aged 15 to 24, shows a more encouraging picture, with 93% being literate globally. This figure has also seen improvement from 87% in 2000. Despite these gains, the World Literacy Foundation reported in 2024 that while global illiteracy had dropped to 9% from 43% in 1980, the sheer number of individuals without basic literacy remains a critical concern.

Regional Disparities in Adult Literacy Rates

Significant regional disparities in adult literacy rates persist, as highlighted by UIS data for the period 2015-2024. Europe and North America boast the highest rates at 98.7%, followed closely by East and Southeast Asia at 96.7%. Latin America and the Caribbean also show strong performance with a 94.8% adult literacy rate.

In contrast, Central and Southern Asia recorded an adult literacy rate of 76.5% during the same period, an increase of 13.2 percentage points from 63.3% between 1995 and 2004. Despite this progress, UNESCO estimates that 347 million people in Central and Southern Asia still lack basic literacy. Sub-Saharan Africa faces the most significant challenge, with an adult literacy rate of 68.5%, up from 59% in 1995-2004.

Challenges in Education and Digital Access

Beyond basic literacy, broader educational challenges continue to affect global populations. Approximately half of all children reach minimum proficiency in reading by the age they should complete primary education, and only about 40% achieve the minimum level in mathematics. Globally, 62% of young people complete upper secondary education, but this figure drops sharply to just 29% in sub-Saharan Africa.

The digital divide further exacerbates these issues, with 2.6 billion people, or 32% of the global population, still lacking internet access today. A substantial 1.8 billion of these individuals reside in rural areas, limiting their access to online educational resources and opportunities.

UIS Data and Future Outlook

The Unesco Institute for Statistics (UIS) continues to be a vital resource for tracking educational progress, with its database containing over 8.26 million published education data points. Since September 2025, 98,368 new education data points have been added, with almost two-thirds of this increase attributed to SDG 4 indicators. Central and Eastern Europe recorded the largest regional increase in available national data, reflecting ongoing efforts to monitor and improve educational outcomes.

Despite the progress marked by International Literacy Day’s 60th anniversary, the persistent challenge of 739 million adults lacking basic literacy skills, coupled with educational and digital access disparities, underscores the continued need for concerted global efforts to achieve truly literate, just, and sustainable societies.
