The following passage from pages 187-190 of Selective Service and Victory: The 4th Report of the Director of Selective Service (Washington: Government Printing Office, 1948) represents the best statistical information available to the United States Army Center of Military History to answer questions about the participation of various minority groups in the armed forces of the United States during the Second World War. Note carefully which of these statistics cover those minorities drafted into the armed forces and which include personnel who voluntarily enlisted. Statistics are extremely difficult to compile since contemporary classifications and the Army's interest in data rarely match modern interests.
