Mali is a landlocked country in West Africa. Around 19 million people live in this approximately 1.24 million km² nation. Its capital is Bamako. Most of the population lives in the southern part of the country, which is flowed through by the two rivers Niger and Senegal. The north extends deep into the Sahara and is extremely sparsely populated.
The main economic sectors of the country are agriculture, fishing and, increasingly, mining. The most important mineral resources include gold, of which Mali is the third largest producer in Africa, and salt. About half of the population lives below the poverty line. The country ranked 184th in the Human Development Index in 2019.
