Approximately 80,000 enumerators conducted the survey. About 20,000 supervisors provided guidance to the enumerators and inspected their documents.
(2)Method of Survey
a.Enumerators checked all the dwellings and other occupied buildings within their assigned enumeration unit districts for the 2003 Housing and Land Survey. They drafted a list of households in the survey and map of their enumeration unit districts and delivered a questionnaire to each selected household during the period from September 23 to 30, 2003. From October 1 to 7, enumerator revisited all selected households in their districts to collect the completed questionnaires and check the entries.
b.One questionnaire, either A or B, was distributed in each enumeration unit district.Questionnaires A and B were allocated at random to individual enumeration unit districts at the ratio of 6 to 1 on average.
c.Questionnaires were completed by the head (or representative) of the household while some parts were filled out by the enumerator during the interview with him/her. For vacant dwellings, the enumerators completed their section of the questionnaire (except for "Type of household") by investigating the exterior of the dwelling. For households who were absent and thus could not complete the questionnaire, the enumerator spoke with the household's neighbors and completed some parts of the questionnaire, such as the name of the head or representative of the household, numbers, type of household, stories of building, construction material, type of building, type of dwelling, width of road abutting the site, site area, and building area.
