The December 2018 report by the World Bank indicated that the poverty rate fell slightly between 2009 and 2014, from 46% to a still high 40.1%. The report provided this updated summary of the country's development challenges: "Burkina Faso remains vulnerable to climatic shocks related to changes in rainfall patterns and to fluctuations in the prices of its export commodities on world markets. Its economic and social development will, to some extent, be contingent on political stability in the country and the subregion, its openness to international trade, and export diversification".
