The economy of Malawi is predominantly agricultural. Over 80% of the population is engaged in subsistence farming, even though agriculture only contributed to 27% of GDP in 2013. The services sector accounts for more than half of GDP (54%), compared to 11% for manufacturing and 8% for other industries, including natural uranium mining. Malawi invests more in agriculture (as a share of GDP) than any other African country: 28% of GDP.
