Major sectors of the Jamaican economy include agriculture, mining, manufacturing, tourism, petroleum refining, financial and insurance services. Tourism and mining are the leading earners of foreign exchange. Half the Jamaican economy relies on services, with half of its income coming from services such as tourism. An estimated 4.3 million foreign tourists visit Jamaica every year. According to the World Bank, Jamaica is an upper-middle income country that, like its Caribbean neighbours, is vulnerable to the effects of climate change, flooding, and hurricanes.
