Economists Shaohua Chen and Martin Ravallion have studied “The Impact of the Global Financial Crisis on the World’s Poorest”. Their analysis shows that the world poverty rate keeps declining despite the crisis:

“The same (post-crisis) growth projections imply that the aggregate $1.25 a day poverty rate will fall from 21% in the “pre-crisis” year of 2008 to 18% (1040 million people) in 2009; the pre-crisis growth rate for 2009 would have instead brought the poverty rate down to 17% (987 million). Using the $2 a day line, the poverty rate falls from 42% in 2008 to 39% (2,232 million) in 2009 under the lower expected growth rate, while the pre-crisis trajectory would have brought the poverty rate down to 38% (2,169 million).”
