The World Bank is a vital source of financial and technical assistance to developing countries around the world. It is not a bank in the common sense but instead made up of two unique development institutions: the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA).
The IBRD focuses on middle income and creditworthy poor countries, while the IDA focuses on the poorest countries in the world.
There are 185 countries that are members of the IBRD and about 10,000 employees of the world bank spread around the world.
