What are the three largest occupational groups in the United States?

According to the data, about 63.1 percent of the United States population was eligible to work and participated in the job market as of 2019. Among this percentage, approximately 50% of the United States population is engaged in the civilian workforce. The civilian labor force includes various occupational groups, with the three largest ones being:

1. Service Occupations

Service occupations encompass a wide range of jobs that provide services to individuals or businesses. This category includes roles such as healthcare workers, retail employees, food service workers, and customer service representatives.

2. Administrative Support

Administrative support roles involve providing clerical and administrative assistance within an organization. This category includes positions like receptionists, secretaries, data entry clerks, and office assistants.

3. Professional Specialty

Professional specialty occupations require specialized knowledge and skills in a specific field. This category includes professions such as doctors, lawyers, engineers, accountants, and information technology specialists.

It is important to note that agricultural workers, military personnel, and federal government employees are not considered part of the civilian workforce when calculating the approximate 50% breakdown of the United States workforce. Therefore, the correct answer to the question is "a. Service occupations, Administrative Support, Professional Specialty."
