Definition: Poverty-weighted Index

Poverty-weighted Index - "an alternative to GNP growth that gives an equal weight to a 1-percent increase in income for any member of society. For example, a 1-percent income growth for the bottom 10 percent would be given the same weight in growth as a 1-percent income growth for the top 10 percent." - source: Economic Development 4th Edition by E.
