In developed countries, which labor sector is typically the most dominant?

• A. Primary
• B. Tertiary
• C. Secondary
• D. Quaternary

Answer: (B)

In developed countries, economic growth shifts focus toward services. The service sector includes activities like health care, education, finance, retail, and information technology. As nations industrialize, farming becomes highly productive with automation, and manufacturing often moves to lower-cost regions, so fewer workers are needed in those areas. Meanwhile, higher incomes and urbanization boost demand for services, from personal care to professional and knowledge-based services. Because these activities absorb the largest share of both jobs and economic output in advanced economies, the service sector becomes the most dominant. Quaternary activities—think research and highly specialized knowledge work—are part of this broad service realm and continue to grow, but the overall dominance sits with services.
