Pharmaceuticals, financial outsourcing, software development, and ecotourism have become the prime industries in Costa Rica's economy. High levels of education among its residents make the country an attractive investing location. Since 1999, tourism earns more foreign exchange than the combined exports of the country's three main cash crops: bananas and pineapples especially, but also other crops, including coffee. Coffee production played a key role in Costa Rica's history and in 2006, was the third cash crop export. As a small country, Costa Rica now provides under 1% of the world's coffee production. In 2015, the value of coffee exports was US$305.9 million, a small part of the total agricultural exports of US$2.7 billion. Coffee production increased by 13.7% percent in 2015–16, declined by 17.5% in 2016–17, but was expected to increase by about 15% in the subsequent year.
