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 Australia
An absolute poverty line was calculated in Australia for the Henderson poverty inquiry in 1973. It was $62.70 a week, which was the disposable income required to support the basic needs of a family of two adults and two dependent children at the time. This poverty line has been updated regularly by the Melbourne Institute according to increases in average incomes; for a single employed person it was $391.85 per week (including housing costs) in March 2009. In Australia the OECD poverty would equate to a "disposable income of less than $358 per week for a single adult (higher for larger households to take account of their greater costs).
