Notes regarding sampling

Survey report contained information on 101 enumeration areas which could not be sampled due to security inaccessibility especially in Borno and Yobe states.

11 survey clusters were dropped across the study, including 1 in Borno state. Also, 11 LGAs (containing 39% of Borno state residents) were dropped and data collection took longer than expected due to security concerns.

  1. First- and third-dose diphtheria-tetanus-pertussis (DTP) coverage as reported from final 2016–17 Multiple Indicators Cluster Survey with National Immunization Coverage Survey supplement (MICS/NICS) and 2018 Demographic and Health Survey (DHS) reports in Borno state. 95% confidence interval (CI) of survey estimate was only provided for DTP3 coverage from the 2018 DHS report. Spatiotemporal model-based geostatistical (MBG) estimates of DTP coverage in the same year are also shown.
  2. *As noted in reports, these estimates are not representative for the entire state.
