Over the past decade, national statistical offices in low- and  middle-income countries have increasingly transitioned to  computer-assisted personal interviewing and computer-assisted telephone interviewing for the implementation of  household surveys. The byproducts of these types of data  collection are survey paradata, which can unlock objective, module- and question-specific, actionable insights on  respondent burden, survey costs, and interviewer effects. 

This study does precisely that, using paradata generated  by the Survey Solutions computer-assisted personal interviewing platform in recent national household surveys  implemented by the national statistical offices in Cambodia, Ethiopia, and Tanzania. Across countries, the average  household interview, based on a socioeconomic household  questionnaire, ranges from 82 to 120 minutes, while the  average interview with an adult household member, based  on a multi-topic individual questionnaire, takes between 13  to 25 minutes.
