This section presents statistics produced by the United Nations Office for Project Services (UNOPS), on behalf of the United Nations system of organizations to provide detailed information covering the spectrum of United Nations procurement activities.

Procurement is defined as the acquisition through purchase or lease of real property, goods or other products (including intellectual property), works or services. Goods are objects of every kind and description including raw materials, products and equipment and objects in solid, liquid or gaseous form, and electricity, as well as services incidental to the supply of the goods if the value of those incidental services does not exceed that of the goods themselves. Services are work, duty or labour performed by a contractor pursuant to a contract. Rendering of services may involve the associated provision of utilities or facilities if specified in the terms of the contract. Typical examples of services include security, catering, cleaning, travel management, event management, IT services, training, freight forwarding, and consulting.
