title: Consumer Expenditure Survey, 2002: Diary Survey
title: Archival Version

description: The ongoing Consumer Expenditure Survey (CES) provides a 
 continuous flow of information on the buying habits of American 
 consumers and also furnishes data to support periodic revisions of 
 the Consumer Price Index. The survey consists of two separate 
 components: (1) a quarterly Interview Survey in which each consumer 
 unit in the sample is interviewed every three months over a 
 fifteen-month period, and (2) a Diary Survey completed by the sample 
 consumer units for two consecutive one-week periods. The Diary Survey 
 contains consumer information on small, frequently-purchased items 
 such as food, beverages, food consumed away from home, gasoline, 
 housekeeping supplies, nonprescription drugs and medical supplies, 
 and personal care products and services. Participants are asked to 
 maintain expense records, or diaries, of all purchases made each day 
 for two consecutive one-week periods. The Consumer Unit 
 Characteristics and Income (FMLY) files supply information on 
 consumer unit characteristics, consumer unit income, and 
 characteristics and earnings of the reference person and his or her 
 spouse. A consumer unit (CU) consists of all members of a particular 
 housing unit who are related by blood, marriage, adoption, or some 
 other legal arrangement. Consumer unit determination for unrelated 
 persons is based on financial independence. Member Characteristics 
 (MEMB) files contain selected characteristics and earnings for each 
 consumer unit member, including information on relationship to 
 reference person. The Detailed Expenditures (EXPN) files present 
 weekly data on expenditures at the Universal Classification Code 
 (UCC) level, while Income (DTAB) files contain data on CU 
characteristics and income at the UCC level.
