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.
Homelessness in the United States by state
Part of the problem lies with long-term joblessness that characterizes the United States' economic crisis. According to the Center for an Urban Future about a third of the adult workers in New York City are low-wage earners, making under $11.54 an hour. Affordable rent rates considered to be no more than a third of the renter's wages. A family in New York City must earn at least $54,000 to find an affordable home. The median household income for renters in the Bronx and Brooklyn is barely $30,000 and $35,000 respectively. According to the Community Service Society, "Two-thirds of poor New Yorkers and over one-third of near poor households—up to twice the poverty level—spend at least half of their incomes on rent ... and place millions of low-income New Yorkers at risk of housing hardships and displacement."
