Poverty threshold
The poverty threshold, poverty limit, poverty line, or breadline is the minimum level of income deemed adequate in a particular country. The poverty line is usually calculated by estimating the total cost of one year's worth of necessities for the average adult. The cost of housing, such as the rent for an apartment, usually makes up the largest proportion of this estimate, so economists track the real estate market and other housing cost indicators as a major influence on the poverty line. Individual factors are often used to account for various circumstances, such as whether one is a parent, elderly, a child, married, disabled, etc. The poverty threshold may be adjusted annually. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries.
In September 2022, the World Bank updated the International Poverty Line (IPL), a global absolute minimum, to $2.15 per day (in PPP). In addition, as of 2022, $3.65 per day in PPP for lower-middle income countries, and $6.85 per day in PPP for upper-middle income countries. Per the $1.90/day standard, the percentage of the global population living in absolute poverty fell from over 80% in 1800 to 10% by 2015, according to United Nations estimates, which found roughly 734 million people remained in absolute poverty.
Charles Booth, a pioneering investigator of poverty in London at the turn of the 20th century, popularised the idea of a poverty line, a concept originally conceived by the London School Board. Booth set the line at 10 (50p) to 20 shillings (£1) per week, which he considered to be the minimum amount necessary for a family of four or five people to subsist on. Seebohm Rowntree (1871–1954), a British sociological researcher, social reformer and industrialist, surveyed rich families in York, and drew a poverty line in terms of a minimum weekly sum of money "necessary to enable families … to secure the necessaries of a healthy life", which included fuel and light, rent, food, clothing, and household and personal items. Based on data from leading nutritionists of the period, he calculated the cheapest price for the minimum calorific intake and nutritional balance necessary, before people get ill or lose weight. He considered this amount to set his poverty line and concluded that 27.84% of the total population of York lived below this poverty line. This result corresponded with that from Booth's study of poverty in London and so challenged the view, commonly held at the time, that abject poverty was a problem particular to London and was not widespread in the rest of Britain. Rowntree distinguished between primary poverty, those lacking in income and secondary poverty, those who had enough income, but spent it elsewhere (1901:295–96).
The poverty threshold was first developed by Mollie Orshansky between 1963 and 1964. She attributed the poverty threshold as a measure of income inadequacy by taking the cost of food plan per family of three or four and multiplying it by a factor of three. In 1969 the inter agency poverty level review committee adjusted the threshold for only price changes.
The term "absolute poverty" is also sometimes used as a synonym for extreme poverty. Absolute poverty is the absence of enough resources to secure basic life necessities.
To assist in measuring this, the World Bank has a daily per capita international poverty line (IPL), a global absolute minimum, of $2.15 a day as of September 2022.
The new IPL replaces the $1.25 per day figure, which used 2005 data. In 2008, the World Bank came out with a figure (revised largely due to inflation) of $1.25 a day at 2005 purchasing power parity (PPP). The new figure of $1.90 is based on ICP PPP calculations and represents the international equivalent of what $1.90 could buy in the US in 2011. Most scholars agree that it better reflects today's reality, particularly new price levels in developing countries. The common IPL has in the past been roughly $1 a day.
These figures are artificially low according to Peter Edward of Newcastle University. He believes the real number as of 2015 was $7.40 per day.
