Enumerators were trained to explain the main objective of the survey to the respondents and encouraged him/her for the participation in the most important and needed mission. Once the respondent was informed about the reason for the visit, enumerator recorded all the relevant information for those members who spent the night in the household. After administering the questionnaire, for the response of individual questionnaire enumerators identified those listed members in the household who fulfilled the criteria as laid down in the household questionnaire.
