The Economic and Social Council and the Secretariat are two of six major organs of the United Nations (UN Organisation Chart).

The five Functional Commissions are each served by a Division in the Department of Economic and Social Affairs of the Secretariat.

The Economic and Social Council includes, in addition to Functional Commissions, Regional Commissions, Programmes and Funds, and Specialized Agencies.

Specialized agencies are autonomous organizations working with the United Nations and each other through the coordinating machinery of the Economic and Social Council.
