Extreme poverty is defined by the international community as living below $1.90 a day, as measured in 2011 international prices (equivalent to $2.12 in 2018). This number, also known as the [[international poverty line]], is periodically updated to account for inflation and differences in the cost of living;<ref>Sala-i-Martin, Xavier.

''The Quarterly Journal of Economics'' 121.2 (2006): 351–397 (370).</ref> it was originally defined at $1.00 a day in 1996. The updates are made according to new price data to portray the costs of basic food, health services, clothing, and shelter around the world as accurately as possible. The latest revision was made in 2015 when the World Bank increased the line to [[Geary–Khamis dollar|international-$]]1.90.

Because many of the world's poorest people do not have a monetary income, the poverty measurement is based on the monetary value of a person's ''consumption''. Otherwise the poverty measurement would be missing the home production of [[subsistence farmer]]s that consume largely their own production.
