Wrong HH weight Tanzania 2012 census?

The Tanzania 2012 census has two weights - person and household - but they are the exact same except in 775 cases. In those cases the household weight is missing.


The Tanzania 2012 census weights (i.e. only the person weights) do not add up to the total popluation in Tanzania as release by the government - it is 3% off - and if one looks at the figures at the sub-country level the numbers are off by 20% in some cases (the official government reports and numbers are in this PDF: http://www.tzdpg.or.tz/fileadmin/docu...)


The IPUMS PDF says that the 2012 census used complex sampling and that the weights for both household and person must be used but that is not possible.


Are the household weights for the 2012 census wrong or is there a problem with the extract for person and household weights?


Thanks!

Thank you for bringing this to our attention. While a 3% difference between data from IPUMS International and the published totals is not entirely implausible, our IPUMS International team is going to take a deeper look into the data. Once they have had time to review the data and the weights, we can provide you with more information.

Dear Michelle,


I wanted to follow up and see if there had been any response from the person you were having look into the household and person weights.


As a reminder: the household and person weights are the exact same in the file. There does not appear to be seperate weights despite the documentation.


Thanks,

Sorry for the delay in responding to this question. The IPUMS International Team has been looking into this issue. I'm told they should have this resolved by the end of July, if not sooner. Thanks for touching base, we will be in touch when the issue with Tanzania sampling weights has been resolved.
