Final answer:
Wholesale trade, retail trade, finance, insurance, and the federal government are part of the service sector, which includes a broad range of service-providing industries that have seen significant growth in developed countries like the US, where they compose over three-quarters of all jobs.
Step-by-step explanation:
According to the U.S. Census Bureau and Bureau of Labor Statistics, wholesale trade, retail trade, finance, insurance, and the federal government are examples of the service sector.
The service sector, also known as the tertiary sector, encompasses a wide range of activities where services are provided to consumers and businesses. This includes, but is not limited to, areas such as entertainment, tourism, media, healthcare, financial and legal industries, and education.
Over time, developed economies like the United States have seen a significant shift from primary and secondary sectors to the tertiary sector, which now accounts for more than three-quarters of all jobs in the U.S.
Jobs in the service industries have shown rapid growth since 1970, creating demand for a variety of service roles, from hands-on customer service to specialized fields such as finance and law.
Moreover, the service sector's flexibility allows for 'footloose jobs' that are not bound to specific locations, unlike jobs in primary and secondary sectors. This versatility has contributed to the expansion of the service sector within the Sun Belt regions, driving innovation and attracting a skilled workforce.
