Has global literacy improved in the past century?

Yes. In 1900, only about 20% of adults worldwide could read and write. Today, global literacy rates exceed 87%, according to UNESCO. The expansion of public education, teacher training, and access to books and digital learning tools have all contributed. Literacy empowers people economically, politically, and socially, lifting entire societies. While gender gaps and regional disparities persist, especially in parts of Africa and South Asia, the long-term trend is positive. Media literacy builds on basic literacy, helping individuals navigate the flood of online content responsibly. Evidence confirms literacy is one of humanity’s greatest success stories.
