Muhammad Yunus founded the Grameen Bank in 1983 to provide microcredit loans to impoverished people without requiring collateral. The bank is based on the concept that the poor have skills that are underutilized and can earn more money with incentives. By 2011, the bank had over 8 million borrowers, 97% of whom were women. It has over 2,400 branches serving over 80,000 villages. Yunus and the Grameen Bank were awarded the 2006 Nobel Peace Prize for their efforts to create economic and social development from below through microcredit lending.
