INTERVIEWERIDHH (HV018) reports the interviewer identification code for the interviewer conducting the household survey. Codes are country- and sample-specific; a given numeric code in one survey refers to a different person than the same numeric code in another survey. Numbering of interviewer codes is not necessarily consecutive; some surveys use "0" as an identification code, for example, while others begin with a 3-digit number. Using the interviewer identification codes, researchers can evaluate whether the quality of responses (e.g., the number of "missing" cases) depended on the person conducting the interview.
