The charts below display personnel of the United Nations system by year and by organization/entity. Data includes personnel with staff contracts or on staff appointments for one year or more.

The table includes separate entries for certain organs of the UN, the ILO and WHO.

Please note, the overall trends are amplified by better reporting systems and an increase in organizations that participate in the UN System.
