IPI Peacekeeping Database

Drawing from archival UN records, the International Peace Institute Peacekeeping Database presents the
first publicly available database of total uniformed personnel contributions of each contributing country
by month, by type (troop, police, or expert/observer) and by mission, from November 1990 to present.

See  Trends in Uniformed Contributions to UN Peacekeeping Operations: A New Dataset, 1991-2012 (Chris Perry and Adam C. Smith)
for a full description of the database and some initial findings from the data regarding overall trends in uniformed contributions to UN peacekeeping.
