I am using the Bangladesh DHS survey for 2017-18 to construct a pseudo baseline for an intervention. I have extracted the clusters which fall into my intervention area using the GPS coordinates. I wonder if, doing the analysis on this subset of clusters, requires me to adjust the weights.

Any advice or documentation on this would be appreciated!

The survey weights of BDHS is calculated taking into consideration the division by residence type as sampling strata. Could you please give more details about your intervention area. Is it a specific division or sub-division? How do you plan to do your intervention, will you select fresh clusters in the same area?

Hope this information is helpful and sufficient.]]>

Thanks for sending the details. The current survey weights are calculated so that the selected sample represent the whole division by urban/rural. As far as I understood, your target areas are the 62 unions only, and therefore your survey weight should be calculated so that the selected clusters are representing clusters on the 62 unions only and not all clusters within the division. I assume, you should be able to do so easily in the intervention survey, since it is part of the selection process. For the DHS to be used as a baseline, if you have access, it would be better if you can adjust the survey weights so it only represent the 62 unions. This might be a complicated process and prone to errors. The other option would be to use the survey weights as they are with the limitations discussed above considered.]]>
