Definition
For women who gave birth in the three to five years before the survey, BIOASSTMEASCODE (V421) reports the code assigned to the assistant measurer of their children's height and weight. Codes are sample-specific; a given numeric code in one sample refers to a different person than the same numeric code in another sample.
Using the measurer (BIOMEASCODE (V420)) and assistant measurer codes, researchers can evaluate whether the quality of responses (e.g., the number of "out of range" cases) depended on the person measuring the children.
