Global poverty has fallen to a record low. The World Bank says 10 percent of the world's population lived on less than $1.90 a day in 2015, down from 11.2 percent in 2013. That means 735.9 million people lived below the poverty threshold in 2015, down from 804.2 million.

Poverty dropped everywhere but the Middle East and North Africa, where conflicts in Syria and Yemen pushed the poverty rate up to 5 percent in 2015 from 2.6 percent in 2013.

The poverty rate was 41.1 percent in Sub-Saharan Africa, 12.4 percent in South Asia, 4.1 percent in Latin America and the Caribbean, 2.3 percent in East Asia and the Pacific and 1.5 percent in Europe and Central Asia.
