Attention to the issues of relative poverty and inequality is intensifying amidst today's fragile global economy. While pre-crisis economic growth generally reduced the incidence of absolute poverty, concerns remain about relative deprivation and social exclusion, which don't necessarily decline just because someone moves out of extreme poverty.

Martin Ravallion elucidated on this during a July 10 lecture at Sydney's UTS Business School, titled "A Fresh Look at Poverty: More Relatively-Poor People in a Less Absolutely-Poor World".
Here is the Powerpoint presentation  from his lecture, which drew from a new working paper he wrote with Shaohua Chen, "More Relatively-Poor People in a Less Absolutely-Poor World ." The paper examines how different regions have been performing in terms of both absolute and relative poverty and identifies the factors that underlie the differences.
