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.
Poverty in the United States
The Organization for Economic Co-operation and Development (OECD) uses a different measure for poverty and declared in 2008 that child poverty in the US is 20% and poverty among the elderly is 23%. The non-profit advocacy group Feeding America has released a study (May 2009) based on 2005–2007 data from the U.S. Census Bureau and the Agriculture Department, which claims that 3.5 million children under the age of 5 are at risk of hunger in the United States. The study claims that in 11 states, Louisiana, which has the highest rate, followed by North Carolina, Ohio, Kentucky, Texas, New Mexico, Kansas, South Carolina, Tennessee, Idaho and Arkansas, more than 20 percent of children under 5 are allegedly at risk of going hungry. (Receiving fewer than 1,800 calories per day) The study was paid by ConAgra Foods, a large food company.
