South Korea reported some 137,899 military deaths and 24,495 missing, 450,742 wounded, 8,343 POW.[8] The US suffered 33,686 battle deaths, 7,586 missing,[282] along with 2,830 non-battle deaths. There were 17,730 other non-battle US military deaths that occurred outside Korea during the same period that were erroneously included as war deaths until 2000.[283][284] The US suffered 103,284 wounded in action.[285] UN losses, excluding those of the US or South Korea, amounted to 4,141 dead and 12,044 wounded in action.
According to the South Korean Ministry of National Defense, there were over 750,000 confirmed violent civilians deaths during the war, another million civilians were pronounced missing, and millions more ended up as refugees.（这应该是南朝鲜部分的平民损失） Estimates of the number of civilians killed in the entire war range from 244,000 to 990,000 for South Korea. The North Korean government has never published estimates of civilian deaths in the war, but more than one million killed has been an estimate common among historians who have studied the Korean War.[307] Over 1.5 million North Koreans fled to the South.

这里面，在过去是把朝鲜战争美军死亡算成54,246人，但是后来政府从中划除17,730人，不在朝鲜，但是我仍然把这部分算进去，因为美军在这三年大部分的活动都是围绕朝鲜战争。

以上总计军事人员伤亡802780，其中韩国62万，美国16万，其余是联合国军其他成分。
这个跟韩国军事历史研究所的表格差不多。

Some 1,789,000 American soldiers served in the war。
美军参战人员中伤亡大概是8％。对比二次大战美军服役人员共一千六百万（其中部分不在战区），伤亡大约一百一十万，比例差不多。
关于平民的伤亡:

华盛顿纪念碑铭文上的数字:
这三张照片里美军的数字，再加上那个1。7万，就是我上面说的美军总损失16万。而UN部分，加在一起超过200万，显然是包括了南朝鲜（不包括北朝鲜的平民损失）。除去我上面的军人损失80万，是大概130万，这130万不知出于何处，与上面段落的平民损失有相当差别。在网上没有找到韩国方面关于平民损失的统计英文的网页。战争时期，人命如草芥，到底多少大概永远无从查考了。
略多。
不像某国，一定有是要“白肺”，又是什么“毛玻璃样”等等，为了尽量缩小死亡数字，国家卫健委连续发布六七版认定标准，为了维持伟光正的形像，非得把COVID 认定标准改得越来越苛刻。
美方伤亡有精确到个人的统计数字， 每一个美军阵亡军人的死亡日期、籍贯（州、郡、市）、出生日期等等 （https://www.archives.gov/research/military/korean-war/casualty-lists/state-level-alpha.html）
共产党的数据，向来是内外有别。即使内部为核实部队战损、战争潜力，有准确的数字，也不会如实公布，因为要坚持洗脑，维护伟光正的形象。
更不用说上下相互隐瞒，向来成风。就拿内战来说，每次战役后，上层都要对下面部队报上去的歼敌数“压缩”，当然下级会坚持，最后上下就核实多少歼敌数“打官司“的例子，在回忆录里比比皆是。
上级呢，即要出成果哄更上一级高兴，又要顾及牛皮不要吹得太离谱，所以才有这官兵相欺，上下相瞒，互相包庇，层层压缩，打数字官司的奇观。
