Service industries are sectors of the economy that provide services rather than goods. These industries include areas such as healthcare, education, hospitality, and finance. They focus on delivering value through activities like teaching, medical care, and customer support, rather than producing physical products. The service industry plays a crucial role in the economy, contributing significantly to employment and GDP. Many people work in service-related jobs, such as waitstaff, teachers, and nurses. As economies evolve, the demand for services continues to grow, reflecting changes in consumer preferences and technological advancements.
