The tertiary industry is the segment of the economy that provides services to its consumers; this includes a wide range of businesses such as financial institutions, schools and restaurants. It is also known as the tertiary sector or service industry/sector. The tertiary industry is one of three industry types in a developed economy, the other two being the primary, or raw materials, and secondary, or goods production, industries. As an economy becomes more developed, it shifts its focus from primary to secondary and tertiary industries.
