According to the data from the U.S. Department of Defense, the United States suffered 33,686 battle deaths, along with 2,830 non-battle deaths, during the Korean War and 8,176 missing in action.[255] South Korea reported some 373,599 civilian and 137,899 military deaths.[12] Western sources estimate the PVA suffered about 400,000 killed and 486,000 wounded, while the KPA suffered 215,000 killed and 303,000 wounded.[27]
Data from official Chinese sources, on the other hand, reported that the PVA had suffered 114,000 battle deaths, 34,000 non-battle deaths, 340,000 wounded, 7,600 missing and 21,400 captured during the war. Among those captured, about 14,000 defected to Taiwan, while the other 7,110 were repatriated to China.[256] Chinese sources also reported that North Korea had suffered 290,000 casualties, 90,000 captured and a "large" number of civilian deaths.[256] In return, the Chinese and North Koreans estimated that about 390,000 soldiers from the United States, 660,000 soldiers from South Korea and 29,000 other UN soldiers were "eliminated" from the battlefield.[256]
Recent scholarship has put the full battle death toll on all sides at just over 1.2 million.[257]
