Sierra Leone is extremely poor and nearly half of the working-age population engages in subsistence agriculture. The country possesses substantial mineral, agricultural, and fishery resources, but it is still recovering from a civil war that destroyed most institutions before ending in the early 2000s. In recent years economic growth has been driven by mining - particularly iron ore. The country’s principal exports are iron ore, diamonds, and rutile, and the economy is vulnerable to fluctuations in international prices. In 2014, rapid spread of Ebolavirus caused a contraction of economic activity in several areas, including transportation, health, and industrial production. Iron ore production dropped, due to low global prices and high costs, driven by the epidemic. A long-term shutdown of the industry would badly hurt the economy because it supports thousands of jobs and creates about 20% of GDP. Until 2014, the government had relied on external assistance to support its budget, but it was gradually becoming more independent. The epidemic has disrupted economic activity, deterred private investment, and forced the government to increase expenditures on health care, straining the budget and restricting other public investment projects. A rise in international donor support will partially offset these fiscal constraints.
