Following are comments from DHS Specialist, Tom Pullum:

DHS does some imputation or reconciliation of incomplete or conflicting dates or ages, for example in birth histories. We may shift out-of-range codes into a not-stated code, as with the height and weight measurements. But we never, or hardly ever, make imputations for missing data and we don't have a policy on how users should make such imputations.

With multiple imputation procedures the interest is in the coefficients produced by a model. The model is run many times, with alternative individual-level imputations, to optimize the values of the coefficients, but multiple imputation is not a device for identifying optimal individual-level imputed values.
