Poverty
The poverty line threshold of $1.90 per day, as set by the World Bank, is controversial. Each nation has its own threshold for absolute poverty line; in the United States, for example, the absolute poverty line was US$15.15 per day in 2010 (US$22,000 per year for a family of four), while in India it was US$1.0 per day and in China the absolute poverty line was US$0.55 per day, each on PPP basis in 2010. These different poverty lines make data comparison between each nation's official reports qualitatively difficult. Some scholars argue that the World Bank method sets the bar too high, others argue it is low. Still others suggest that poverty line misleads as it measures everyone below the poverty line the same, when in reality someone living on $1.20 per day is in a different state of poverty than someone living on $0.20 per day. In other words, the depth and intensity of poverty varies across the world and in any regional populations, and $1.25 per day poverty line and head counts are inadequate measures.
Economy of the United States
In 2016, 12.7% of the U.S. population lived in poverty, down from 13.5% in 2015. The poverty rate rose from 12.5% in 2007 before the Great Recession to a 15.1% peak in 2010, before falling back to just above the 2007 level. In the 1959–1962 period, the poverty rate was over 20%, but declined to the all-time low of 11.1% in 1973 following the War on Poverty begun during the Lyndon Johnson presidency. In June 2016, The IMF warned the United States that its high poverty rate needs to be tackled urgently.
