The poverty threshold or poverty line is the minimum level of income deemed adequate in a particular country. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries. In October 2015, the World Bank updated international poverty line to US$1.90 a day. In 2008, the World Bank came out with a figure (revised largely due to inflation) of $1.25 at 2005 purchasing-power parity (PPP). The common international poverty line has in the past been roughly $1 a day. At present the number of people living under extreme poverty is likely to fall below 10 ccording to the World Bank projections released in 2015.
