There was no problem with the data quality, although there was often some ambiguity about the meaning of CURRENT PLACE OF RESIDENCE, especially in urban areas. The feeling was that there had been very little use of that information, and researchers who were interested in doing migration analysis would really need much more information than was being collected. When the DHS-6 questionnaire was being designed, there was an attempt to delete some low priority questions to keep the questionnaire of manageable size. That question is now back in the DHS-7 model questionnaire, but CURRENT PLACE OF RESIDENCE has been changed to CURRENT CITY, TOWN, OR VILLAGE OF RESIDENCE to make the meaning clearer. A new question has also been added in DHS-7 to provide more detailed migration information ("Before you moved here, which [PROVINCE/REGION/STATE] did you live in?").
