The Consumer Expenditure Survey (CE) program provides a continuous and comprehensive flow of data on the buying habits of American consumers. These data are used widely in economic research and analysis, and in support of revisions of the Consumer Price Index. To meet the needs of users, the Bureau of Labor Statistics (BLS) produces population estimates for consumer units (CUs) of average expenditures in news releases, reports, issues, and articles in the Monthly Labor Review. Tabulated CE data are also available on the Internet and by facsimile transmission (See Section XVI. APPENDIX 5).
These microdata files present detailed expenditure and income data from the Interview
component of the CE for 2005 and the first quarter of 2006. The Interview survey collects data on up to 95 percent of total household expenditures. In addition to the FMLI, MEMI, MTBI, and ITII files, the
microdata include files created directly from the expenditure sections of the Interview survey
(EXPN files). The EXPN files contain expenditure data and ancillary descriptive information, often not
available on the FMLI or MTBI files, in a format similar to the Interview questionnaire. In addition to the extra information available on the EXPN files, users can identify distinct spending categories easily and reduce processing time due to the organization of the files by type of expenditure.
Estimates of average expenditures in 2005 from the Interview Survey, integrated with data from
the Diary Survey, will be published in the report Consumer Expenditures in 2005 (due out in 2007). A list of recent publications containing data from the CE appears at the end of this documentation.

Sampling
Sampling Procedure
There was a sample redesign in 2005. The sampling frame is now generated from the 2000 Population Census 100-percent-detail file. As a result, users will not be able to link all consumer units whose participation spanned 2004 and 2005 sample designs. It is suggested that users use the 2003 and 2004 data or the 2005 and 2006 data for any micro-level longitudinal analysis. 2005 data users should be aware that the 2005 first quarter (q051) data on the 2004 data are from the old sample design, while the q051 data on the 2005 data are from the new sample design. Consequently, the data are not the same.
Due to the sample design change, there are no January interview data on the q051 files of the 2005 data. Please be aware that collection period estimates (see section V.A.1.b.) will be affected because of this. Aggregate collection period estimates will require inflation by factors of 3/2 (for q051 estimates) to 12/11 (for 2005 annual collection period estimates). This adjustment will roughly compensate for the missing January interviews. For calculations of averages, January interview data are missing from both the numerator and the denominator and these estimates are not as severely affected. Calendar period estimates are not affected because all expenditures from January interviews fall into the q044 time period.
