“According to data compiled by Our World in Data and the World Bank, the literacy rate of the world’s population from secondary school age onward was only 12 percent in 1820 – around one person in ten. In 1900, it still barely exceeded 20 percent. From the 1950s on, world literacy began to take off, hitting 42 percent in 1960 and 70 percent in 1983. Today, the global literacy rate stands at 87 percent, or almost nine out of ten people worldwide.” (more)
