The power of the interviewer

Abstract

BACKGROUND African censuses and surveys remain dependent on interviewers for data collection. Data quality is assured through training and supervision. Many survey concepts are difficult to translate into African languages and some, such as "household", may have multiple criteria which are not fulfilled by everyone, leading interviewers to prioritise different criteria. Some questions introduce unfamiliar ideas which require considerable negotiation by interviewers to obtain acceptable answers. OBJECTIVE To identify key stages in the data collection process and domains where interviewer judgement and interviewer-respondent social dynamics play a substantial role in determining who is included in household surveys, and in shaping responses to questions. METHODS We analyse published definitions, enumerator manuals and qualitative interview data with households, interviewers, supervisors, trainers, survey organisers and analysts along the chain of data production and use in Tanzania, Uganda, Senegal and Burkina Faso. ©2013 Randall, Coast, Compaore & Antoine.
