Key Insights
Youth Literacy Advantage
Youth literacy (ages 15–24) has reached over 93% globally. As younger, educated generations age into adulthood, global adult literacy is projected to approach 95% by 2040.
Gender Gap Progress
The literacy gender gap has narrowed substantially over the past three decades. While women still constitute ~64% of illiterate adults globally, youth gender parity in literacy has been achieved in most world regions.
Regional Disparities
Developed countries and East Asia report 99%+ literacy. Sub-Saharan Africa and Southern Asia face the largest remaining challenges, though adult literacy in both regions has grown by 20+ percentage points since 1990.
Digital Literacy Expansion
Modern literacy definitions increasingly encompass digital literacy—the ability to navigate, evaluate, and produce information using digital devices and internet platforms.
