We have prepared data files to add IWI to a large number of DHS and MICS surveys. These files contain the value of IWI for all households plus the DHS/MICS household IDs. On the basis of the Ids, IWI can be connected to the households in the original datasets. Using these files it is not necessary any more to do the tedious coding work. Given that the files contain information at the household level, we can only make them available to users after having obtained permission of DHS/MICS for this. Please contact us if you are interested in this option.
