The v program provides data on consumer expenditures, income and demographic characteristics in the United States. The CE program provides these data in tables, LABSTAT database, news bulletins, reports, and public-use microdata files. CE data are collected by the Census Bureau for BLS in two surveys, the Interview Survey for major and/or recurring items and the Diary Survey for smaller or more frequently purchased items. CE data are primarily used to revise the relative importance of goods and services in the market basket of the Consumer Price Index. CE is the only federal household survey to provide information on the full range of consumer spending and income. Here is an overview of the CE program and its methods.
