SIPRI has been collecting comprehensive, reliable and authoritative data on multilateral peace operations since the early 1990s. The data is made available in the SIPRI Yearbook and in SIPRI’s Multilateral Peace Operations Database.
The data includes annual statistics on personnel, country contributions, fatalities and budgets for peace operations conducted by the United Nations, regional organizations or alliances, and ad hoc coalitions of states. The data in the database is used to survey and analyse significant trends and shifts, measure their impact on current policy issues, and provide evidence-based background briefings and policy recommendations to multilateral organizations, troop-contributing countries, donors and the public.
