The Perpetual Education Fund is essential a microfinance operation run by The Church of Jesus Christ of Latter-day Saints (Mormons). It provides small education loans to LDS return missionaries in Latin America and a few other countries. They repay the loan with minimal interest (somewhere in the neighborhood of 1-2% annual) so the funds can be used to help someone else.
For those of you having trouble downloading the graphic, it shows there have been 46,000 participants in the program's first 10 years in 45 countries. The average education program takes 2.5 years. Slightly more than half of the participants are women. The average loan goes to a 24 year old who triples or quintuples their income.
