The document discusses the tertiary sector and services in Spain. It begins by asking if the tertiary sector only has an economic function. It then discusses that the tertiary activities that employ the most people in Spain are social services like administration, education, and healthcare. This is likely because Spain has expanded compulsory education and provides universal, free primary healthcare and specialist services, though economic crisis has led to cuts in healthcare spending. The document classifies tertiary activities and provides a case study on healthcare and education in Spain.
