Meanwhile, the US, China and Russia are the top countries that have the half of the total female prison population.
The researchers say their study should be of "profound concern" to governments worldwide is a fundamental source for government’s policy. The report is based on datas from 219 countries and dependant territories.
"(Women and girls) are an extremely vulnerable and disadvantaged group, and tend to be victims of crime and abuse themselves," said Dr Jessica Jacobson, co-director of the institute, which is part of Birkbeck College.
African countries have the lowest rate of women in jail in the world, while El Salvador, Brazil, Cambodia and Indonesia experience sharp increases.
