Procedures for selection of sample clusters: In the catchment area of a CC there are 8 routine EPI centers (including the CCs one) each serving, on an average, ~1000 people (or ~235 households). The catchment area of the EPI centre will be treated as 'cluster'. Given the crude birth rate of ~20 per 1000 population per year there will be 20 mothers who have a infant aged 0-11 months eligible to provide information on ANC, delivery care and PNC; and another 20 mothers who have a toddler aged 12-23 months eligible to provide information on child vaccination. As such, 33 EPI centers from the list of EPI centers of an upazila (with at least one EPI centre per CC) in the selected sub-district will be randomly chosen for survey.
