Hello,
I'm trying to calculate and approximate level-weights for multilevel analysis using 2018 Nigeria Demographic and Health Survey, but the total number of households in the country and the average EA size (i.e. average number of households per cluster) are missing from the report.
Please how do I get these information.
Thank you.

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
If you enter "label list V023" you will see that two strata (strata 2 and 3) have the same name, "South Buganda". In Tables A1 and A2 they are combined as "South Central". Another two strata (strata 4 and 5) have the same name, "North Buganda", and they are combined as "North Central". It looks like v023= 30 and 31 have also been aggregated with South Central and v023=32 and 33 have also been aggregated with North Central. It looks like v023=34 has been aggregated with Busoga. (You can confirm this with "tab v023 if v024<=3"
I think the best option for you would be to redefine v023 to match up with the combinations of v024 and v025, for which you have the necessary numbers in A2 and A3, and then proceed. Ideally you would have more numbers in A2 and A3, and wouldn't have to do this.
In general, that is, in most surveys, v023 is the same as the combinations of v024 and v025. This survey appears to be an exception to that, probably because North Central, South Central, and Busoga have large populations and there was a desire to subdivide them.
