联合国系统包括联合国自身以及被称为方案、基金和专门机构的多个附属组织。这些组织有自己的会员、领导和预算。联合国各方案和基金通过自愿捐助而非分摊会费获得资金。各专门机构是独立的国际组织，并通过自愿捐助和分摊会费获得资金。

The UN system is made up of the UN itself and many programmes, funds, and specialized agencies, all with their own members, leadership and budget. The programmes and funds are financed through voluntary rather than assessed contributions. The Specialized Agencies are independent international organizations funded by both voluntary and assessed contributions.
