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
Many sociologists and government officials have argued that poverty in the United States is understated, meaning that there are more households living in actual poverty than there are households below the poverty threshold. A recent NPR report states that as many as 30% of Americans have trouble making ends meet and other advocates have made supporting claims that the rate of actual poverty in the US is far higher than that calculated by using the poverty threshold. A study taken in 2012 estimated that roughly 38% of Americans live "paycheck to paycheck."
