According to data from a scientific research institution in 2019, about 86% of adults in the world today have the ability to read and write, although many people still feel incredible. But if you compare this number with 1820, this is definitely a huge progress for human beings.
Because in 1820 only 12% of the world had reading skills, and in 2016 it showed an almost opposite figure, namely only 14% of the world’s illiterate. It can be said that in the past 65 years, the global literacy rate has increased by 4% every 5 years, from 42% in 1960 to 86% in 2015. And, more importantly, the population of the planet is constantly growing.
