Services are a big part of economies, especially in developed countries. They have different ways of being traded, which can be tricky to calculate. Even though services trade is growing, it's still not as big as trade in goods. The EU is a major player in services trade, with richer countries focusing on business services and others on travel. Trade barriers can make it harder to trade services across borders. The EU has a common market that helps with trading services within the EEA, but different countries have different levels of protection for different types of services.
