Providing for Peacekeeping: Annual Peak UN DeploymentsProviding for Peacekeeping：联合国维和年度峰值部署

Providing for Peacekeeping records countries' uniformed personnel contributions to United Nations peacekeeping operations. The preserved official raw data contain contributor-mission-month observations measured at month end from November 1990 through February 2020. Each hosted row is one contributor-mission-year and reports the maximum Total personnel stock observed in that calendar year plus the number of observed months. Annual peak deployment is a maximum of monthly end-of-month stocks, not a sum, so personnel present across months are not double-counted. months_observed identifies partial relation-years and the partial boundary years.

Providing for Peacekeeping 记录各国向联合国维和行动提供的制服人员。保留的官方原始数据以贡献国—任务—月份为单位，数值是 1990 年 11 月至 2020 年 2 月的月末存量。网站数据每行是一条贡献国—任务—年度记录，报告该日历年内官方 Total 月末存量的最大值及实际观测月份数。年度峰值是月末存量的最大值而非求和，避免将跨月持续部署重复计算；months_observed 用于识别关系层面的不完整年度及首尾边界年份。
