Recent Trends in US Income and Expenditure Poverty

After many years of following similar trends, U.S. poverty rates measured by household spending in data from the U.S. Consumer Expenditure Survey (CE) fell between 2000 and 2008, while poverty measured by income rose. Comparisons of spending and income poverty in the CE with income poverty in other surveys, spending data from the Panel Study of Income Dynamics, and a time series of employment levels, find the CE to be the outlier. The findings do not bear directly on the primary use of CE data in providing category weights for calculation of the Consumer Price Index, but do require explanation not available in CE public-use files.
