The OES survey categorizes workers into 810 detailed occupations based on the Office of Management and Budget’s 2010 Standard Occupational Classification (SOC) system. Together, these detailed occupations make up 22 of the 23 SOC major occupational groups. Major group 55, Military Specific Occupations, is not included.
