The term "service sector" refers to the portion of the economy devoted to providing services rather than goods. Also called the "tertiary sector," the service sector joins two other sectors centered on manufacturing and agriculture.
Examples of jobs in the service sector include retail clerks, restaurant workers, bank tellers, educators, health care providers and realtors. Countries generally aim to diversify their economies between the three sectors, although some, including the United States, the United Kingdom, Japan and Australia, focus more on service-sector jobs. As of 2014, the service sector was the fastest growing sector of the U.S. economy. The United States derives two-thirds of its gross domestic product from service-sector participation.
