The increase in literacy rates is mainly driven by the expansion of access to education, especially in developing countries. In the past few decades, many countries have implemented policies to increase the enrollment and retention rates of children in primary and secondary schools. In addition, the rise in female literacy rates has also contributed to the overall increase in global literacy.
However, there are still significant disparities in literacy rates between different regions of the world. In general, literacy rates are highest in developed countries and lowest in developing countries. For example, in 2015, the literacy rate in the developed countries was 99%, while the literacy rate in the developing countries was 76%.
To further improve global literacy rates, continued efforts are needed to ensure that all children have access to quality education, regardless of their background or socioeconomic status. This includes addressing the challenges of poverty, discrimination, and lack of resources that often prevent children from attending school. Additionally, promoting literacy programs for adults is also essential to improve the overall literacy rate and foster social and economic development.
