About 10 percent of people have completed primary education – which runs from nursery to 11 or 12 years old – with an additional five percent having incomplete primary school education.
Nearly 40 percent of the world’s population has been educated to either lower or upper secondary education, which usually runs from the ages of 11 or 12 through to 18 or 19 years old.
