Comprehensive data on consumption expenditures have historically not been collected in US longitudinal household surveys. The Panel Study of Income Dynamics (PSID) expanded its expenditure data collection in 1999 and 2005. We examine these new expenditure data, highlighting several unique features of the PSID data. We then compare the PSID expenditure data with those in the Consumer Expenditure Survey (CE). We document that the PSID data cover nearly the entire scope of the CE data, and the mean statistics of total expenditures compare favorably between the two surveys. However, significant differences remain for certain expenditure categories.
