A fall to cheer

THE past four years have seen the worst economic crisis since the 1930s and the biggest food-price increases since the 1970s. That must surely have swollen the ranks of the poor.

Wrong. The best estimates for global poverty come from the World Bank's Development Research Group, which has just updated from 2005 its figures for those living in absolute poverty (not be confused with the relative measure commonly used in rich countries). The new estimates show that in 2008, the first year of the finance-and-food crisis, both the number and share of the population living on less than $1.25 a day (at 2005 prices, the most commonly accepted poverty line) was falling in every part of the world. This was the first instance of declines across the board since the bank started collecting the figures in 1981 (see chart).
