Which of the following is not true of the World Bank's "dollar-per-day" poverty line? Group of answer choices It was established to minimize the effects of changes in PPP-adjustments on global poverty headcounts. If the poor pay higher prices for food than the prices recorded when constructing PPP estimates, then estimates of poverty within a country using this line will be too low. It began in 1990 as an attempt to set a global poverty line based on the mean poverty lines of several of the poorest countries in the world for which there were survey data. The poverty line was raised due to changes in PPP conversions that have adjusted the dollar-equivalent of incomes in several poor countries upwards relative to rich countries Some have argued that it raises international awareness of the problem of extreme poverty more than it actually helps national authorities devise anti-poverty programs. The "dollar-a-day" line is now $2.15/day
