This paper reviews the empirical evidence on the levels and trends in
income/consumption inequality and poverty in developing countries. It
includes a discussion of data sources and measurement issues, evidence
on the levels of inequality and poverty across countries and regions, an
assessment of trends in these variables since the early 1980s, and a
general discussion of their determinants. There has been tremendous
progress in the measurement of inequality and poverty in the developing
world, although serious problems of consistency and comparability still
remain. The available evidence suggests that on average the levels of
national income inequality in the developing world increased in the
1980s and 1990s, and declined in the 2000s. There was a remarkable fall
in income poverty since the early 1980s, driven by the exceptional
performance of China over the whole period, and the generalized
improvement in living standards in all the regions of the developing
world in the 2000s.
This paper is also a chapter in the 'Handbook of Income Distribution'
Volume 2 and edited by Anthony B. Atkinson and François Bourguignon.
