title: Consumer Expenditure Survey, 1991: Diary Survey
title: Version 1

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 15-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 were asked to maintain expense 
 records, or diaries, of all purchases made each day for two consecutive 
 one-week periods. Information was also elicited at the end of the 
 two-week period on work experience, occupation, industry, retirement 
 status, earnings from wages and salaries, net income from business or 
 profession, net income from one's own farm, and income from other 
 sources. 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 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 for each 
 consumer unit member, including reference person and spouse. The 
 Detailed Expenditures (EXPN) files present weekly data on expenditures 
 at the Universal Classification Code (UCC) level, while the Income 
(DTAB) files contain weekly data on income at the UCC level.
description: This survey is based on a national probability sample of 
 households. The sampling frame for this survey (i.e., the list from 
 which housing units were chosen) was generated from the 1980 Census 
 100-percent detail file. Each selected sample unit is requested to keep 
 two one-week diaries of expenditures over consecutive weeks. The 
 earliest possible day for placing a diary with a household is 
 predesignated so that each day of the week has an equal chance to start 
 the reference week and the diaries are evenly spaced throughout the 
 year. During the last six weeks of the year, the diary sample is 
 supplemented to twice its normal size to increase the reportings of 
types of expenditures unique to the holiday season.
