Here is a good site:
"The Consumer Expenditure Survey (CE) program consists of two surveys collected for the Bureau of Labor Statistics by the Census Bureau — the quarterly Interview survey and the Diary survey — that provide information on the buying habits of American consumers, including data on their expenditures, income, and consumer unit (families and single consumers) characteristics."
