See the below image. It seems that many of the PSU level variables in IPUMS are missing for NFHS 3 even when the variables that are being used to create these estimates exist for this round.
For instance: IMPWATERPSU is missing for round 3 even though DRINKWTR, PSU and HHWEIGHT are available for NFHS 3. I want to understand if there is any reason for systmatically excluding these variables for this round
“IMPWATERPSU reports the percentage of households that used an improved source for drinking water, based on the variable [DRINKWTR], in the primary sampling unit. This variable has been calculated by IPUMS using Chapter 16 of the [DHS Guide to Statistics 8and weighted using the variable [HHWEIGHT].”
