Since 2000, the United Nations has marked International Mother Language Day on February 21. The 2023 theme is "Multilingual education – a necessity to transform education."

Globally 40 per cent of the population does not have access to an education in a language they speak or understand. But progress is being made in multilingual education with growing understanding of its importance, particularly in early schooling, and more commitment to its development in public life.
