Re: st: Analysis on subset of Demographic and Health Survey (DHS) data

French,

the data is usually processed for several weeks or even months. Not
all reports are produced simultaneously, (as described here:
http://www.measuredhs.com/data/Data-Processing.cfm) and in some cases
the problems are uncovered, which may necessitate revision of data
files. According to this second source:
http://www.nbs.go.tz/tnada/index.php/catalog/12/datafile/F7
the data file of "children recode" contains indeed 8023 children,
which is what you have in your sample. It is the most straightforward
solution to contact Macro International (measuredhs.com) to ask
whether there were any revisions to the data and what were the reasons
for them. And even if the discrepancy is not caused by the revisions
to data, but e.g. to the way the data is filtered in your program
(which I don't see happening, as you simply load the data) they would
be able to figure that out. So don't hesitate and give them a call.

Best, Sergiy Radyakin
