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.
Working poor
Poverty is often associated with joblessness, but a large proportion of poor people are actually working or looking for work. In 2009, according to the US Census Bureau's official definition of poverty, 8.8 million US families were below the poverty line (11.1% of all families). Of these families, 5.19 million, or 58.9%, had at least one person who was classified as working. In the same year, there were 11.7 million unrelated individuals (people who do not live with family members) whose incomes fell below the official poverty line (22% of all unrelated individuals). 3.9 million of these poor individuals, or 33%, were part of the working poor. The cost of raising a child from birth to age 18 for a middle-income, two-parent family averaged $226,920 last year (not including college), according to the U.S. Department of Agriculture. That's up nearly 40% -- or more than $60,000—from 10 years ago. Just one year of spending on a child can cost up to $13,830 in 2010, compared to $9,860 a decade ago.
