HWHTHOWMEAS (HW15) reports whether the height of children under age 5 was measured when they were lying down or standing up. According to the DHS Recode Manuals:
In DHS surveys, children aged less than 24 months are to be measured lying down, children 24 months or older are to be measured standing up. There may, however, be a considerable discrepancy between policy and practice!
