Top executives are found in every industry, but service-providing industries, including government, employ almost 8out of 10.

Chief executives and legislators in the Federal Government consist of the 100 Senators, 435 Representatives, and the President and Vice President. State governors, lieutenant governors, legislators, chief executives, professional managers, and council and commission members of local governments make up the remainder.

Government chief executives and legislators who do not hold full-time, year-round positions often continue to work in the occupation that they held before being elected.
