confidentiality.Finally, in addition to the classroom instruction, the ZDHS training included practice interviews usingthe questionnaire in English and the participants’ local languages.Data collection for the 2001-2002 ZDHS took place over a seven-month period from November 2001to May 2002. Twelve interviewing teams carried out data collection. Each team consisted of one team supervisor,one field editor, three to four female interviewers, one male interviewer, one nurse/nurse counselor, onelab technician, and one driver. Six staff assigned from the CSO coordinated and supervised fieldwork activities.They were assisted by staff from the TDRC and the University of Zambia Demography Division. ORCMacro participated in field supervision for interviews, height and weight measurements, and blood collectionand testing.1.11 DATA PROCESSINGThe processing of the ZDHS results began shortly after the fieldwork commenced. Completed questionnaireswere returned periodically from the field to CSO offices in Lusaka, where they were entered andedited by data processing personnel who were specially trained for this task. The concurrent processing of thedata was an advantage because CSO was able to advise field teams of problems detected during the data entry.TDRC provided the results of the syphilis and HIV testing to CSO for entry and editing. The data entryand editing phase of the survey was completed in August 2002.1.12 RESPONSE RATESTable 1.2 shows response rates for the2001-2002 ZDHS. Response rates are a sourceof concern because high non-response mayaffect the reliability of the results. A total of8,050 households were selected in the sample,of which 7,260 were found at the time of thefieldwork. The shortfall is largely due to somestructures being vacant. Of the 7,260 existinghouseholds, 7,126 were successfully interviewed,yielding a household response rate of98 percent.In the households interviewed in thesurvey, a total of 7,944 eligible women wereidentified; interviews were completed with7,658 of these women, yielding a response rateof 96 percent. With regard to the male surveyresults, 2,418 eligible men were identified in thesubsample of households selected for the malesurvey, of which 2,145 were successfully interviewed,yielding a response rate of 89 percent.The response rates are lower for the urban thanfor rural sample, especially for men.Table 1.2 Results of the household and individual interviewsNumber of households, number of interviews, and response rates,according to residence, Zambia 2001-2002ResidenceResult Urban Rural TotalHousehold interviewsHouseholds selected 2,167 5,883 8,050Households occupied 2,059 5,201 7,260Households interviewed 2,013 5,113 7,126Household response rate 97.8 98.3 98.2Interviews with womenNumber of eligible women 2,650 5,294 7,944Number of eligible women interviewed2,551 5,107 7,658Eligible woman response rate 96.3 96.5 96.4Interviews with menNumber of eligible men 814 1,604 2,418Number of eligible men interviewed689 1,456 2,145Eligible man response rate 84.6 90.8 88.710 | IntroductionCompared with the 1996 ZDHS, there has been a slight decline in response rates. In the 1996 survey,the response rates were 99 percent for households, 97 percent for women, and 91 percent for men (CSO, MOH,and Macro International, 1997).The principal reason for non-response among both eligible men and women was the failure to find individualsat home despite repeated visits to the household. The substantially lower response rate for men reflects
