Vietnam Population and AIDS Indicator Survey 2005 ... - Measure DHS

to process complex surveys. All data were entered twice (100 percent verification). The concurrent
processing of the data was a distinct advantage for data quality, as VPAIS staff was able to advise field
teams of errors detected during data entry. The data entry and editing phases of the survey were
completed by the end of December 2005.
1.10 RESPONSE RATES
Table 1.1 shows response rates for the VPAIS. A total of 6,446 households were selected in the
sample, of which 6,346 (98 percent) were found to be occupied at the time of the fieldwork. Occupied
households include dwellings in which the household was present but no competent respondent was
home, the household was present but refused the interview, and dwellings that were not found. Of
occupied households, 6,337 were interviewed, yielding a household response rate close to 100 percent.
Calculation of response rates is defined in Appendix A.

All women and men aged 15-49 years who were either permanent residents of the sampled
households or visitors present in the household during the night before the survey were eligible to be
interviewed in the survey. Within interviewed households, a total of 7,369 women aged 15-49 were
identified as eligible for interview, of whom 7,289 were interviewed, yielding a response rate to the
Individual interview of 99 percent among women. The high response rate was also achieved in male
interviews. Among the 6,788 men aged 15-49 identified as eligible for interview, 6,707 were successfully
interviewed, yielding a response rate of 99 percent. Response rates are almost identical in urban and rural
areas. Response rates for the three regions and the four targeted provinces are shown in Appendix A;
response rates are above 96 percent for all seven sub-groups.
