The tertiary sector makes up 66% of employment in Europe and 64% in Spain. It includes service jobs like trade, transport, and tourism. Trade involves both domestic commerce within a country and foreign commerce between countries, with Spain exporting products like food and cars while importing vehicles, fuels, and machinery. Transport is crucial for moving people and goods, with major European ports and Spain's dense railway and road networks. Tourism is also important economically, with Spain as the third most visited country and attractions like beaches, culture, and rural life drawing visitors to Europe.
