Collectively known as the World Bank, the International Bank for Reconstruction & Development (IBRD) and its sister organization the International Development Association (IDA) are on a mission to improve the world. The IBRD strives to reduce poverty in creditworthy middle-income countries by promoting sustainable development through loans, guarantees, risk management products, and advisory services. It serves countries in Latin America, Asia, Africa, and Eastern Europe, funding development activities by selling bonds in international capital markets. IDA assists the world's poorest countries, helping them develop effective health care, education, and government institutions.
