The World Bank Group consists of five institutions:

• International Bank for Reconstruction and Development (IBRD)
  • IBRD aims to reduce poverty in middle-income and creditworthy poorer countries.
• International Development Association (IDA)
  • Contributions to IDA enable the World Bank to provide $6–7 billion per year in interest-free credits to the world’s 78 poorest countries.
• International Finance Corporations (IFC)
  • IFC’s mandate is to further economic development through the private sector.
• Multilateral Investment Guarantee Agency (MIGA)
  • MIGA helps encourage foreign investment in developing countries, provides technical assistance to help countries disseminate information on investment opportunities, and offers investment dispute mediation on request.
• International Centre for the Settlement of Investment Disputes (ICSID)
  • ICSID helps to encourage foreign investment by providing international facilities for conciliation and arbitration of investment disputes, in this way helping to foster an atmosphere of mutual confidence between states and foreign investors.

• IBRD: 184 Governments
• IDA: 163 Governments
• IFC: 175 Governments
• MIGA: 158 Governments
• ICSID: 134 Governments

As noted on the World Bank's website: "Each of the World Bank Group organizations operates according to procedures established by its articles of agreement or an equivalent founding document. These documents outline the conditions of membership and the general principles of organization, management, and operations."

As described on the organization's website: “The World Bank Group’s Global Information & Communication Technologies Department (GICT) plays an important role in developing and promoting access to information and communications technologies (ICT) in developing countries. Created in January 2000, GICT brings together the private investment practice of [the International Finance Corporation] and the public sector advisory and funding arms of the World Bank, to provide governments, private companies and community organizations with the capital and expertise needed to develop and exploit ICT to reduce poverty and foster development.”
