The economy of Sierra Leone is $4.082 billion by gross domestic product as of 2018. Since the end of the Sierra Leone Civil War in 2002, the economy is gradually recovering with a gross domestic product growth rate between 4 and 7%. In 2008 it in PPP ranked between 147th by World Bank, and 153rd by CIA, largest in the world. Sierra Leone's economic development has always been hampered by an overdependence on mineral exploitation. Successive governments and the population as a whole have always believed that "diamonds and gold" are sufficient generators of foreign currency earnings and lure for investment. As a result, large scale agriculture of commodity products, industrial development and sustainable investments have been neglected by governments. The economy could thus be described as one which is "exploitative" - a rentier state - and based upon the extraction of unsustainable resources or non-reusable assets. Two-thirds of the population of Sierra Leone are directly involved in subsistence agriculture. Agriculture accounted for 58 percent national GDP in 2007. Economic history This is a chart of trend of gross domestic product of Sierra Leone at market prices estimated by the International Monetary Fund and EconStats with figures in millions of Sierra Leones. Current GDP per capita of Sierra Leone grew 32% in the 1960s, reaching a peak growth of 107% in the 1970s. But this proved unsustainable and it consequently shrank by 52% in the 1980s and a further 10% in the 1990s. The mean wage was US$0.32 per hour in 2009. Economic sectors Agriculture Two-thirds of the population of Sierra Leone are directly involved in subsistence agriculture. Agriculture accounted for 58 percent national Gross Domestic Product (GDP) in 2007. Agriculture is the largest employer with 80 percent of the population working in the sector. Rice is the most important staple crop in Sierra Leone with 85 percent of farmers cultivating rice during the rainy season and an annual consumption of 76 kg per person. Mining Rich in minerals, Sierra Leone has relied on the mining sector in general, and diamonds in particular, for its economic base. In the 1970s and early 1980s, economic growth rate slowed because of a decline in the mining sector. Financially disadvantageous exchange rates and government budget deficits led to sizable balance-of-payments deficits and inflation. Certain policy responses to external factors as well as implementations of aid projects and maintenance have led to a general
