According to the 4th Report of the Director of Selective Service of 1948, a total of 51,438 Puerto Ricans served in the Armed Forces during World War II, however the Department of Defense in its report titled "Number of Puerto Ricans serving in the U.S. Armed Forces during National Emergencies" stated that the total of Puerto Ricans who served was 65,034 and from that total 2,560 were listed as wounded. Unfortunately, the exact total amount of Puerto Ricans who served in World War II in other units, besides those of Puerto Rico, cannot be determined because the military categorized Hispanics under the same heading as whites. The only racial groups to have separate statistics kept were African-Americans and Asian Americans.
