• The Master Sample Frame (MSF) for the NDHS was designed and compiled by the PSA, based on the listing of households from the 2010 and 2015 Censuses of Population

  
• The MSF involved a systematic selection of 1,247 primary sampling units (PSUs) distributed by province or HUC, with an equal take of sample housing units selected from each PSU using systematic random sampling
• All women aged 15–49 who were either usual residents of selected households or visitors who stayed the night before the survey were eligible to be interviewed
• Two questionnaires were used for the 2022 NDHS: the Household Questionnaire and the Woman’s Questionnaire, which collected information on various topics including sociodemographic characteristics, reproduction, family planning, and health issues
• The Household Questionnaire collected basic demographic information for each person listed, health insurance coverage, characteristics of the household’s housing unit, and specific sections on health facility utilization, knowledge of local health programs, and diseases
• The Woman’s Questionnaire collected information on reproduction, family planning, maternal and newborn health care, vaccination, children’s nutrition, women’s safety, and other health issues
• The NDHS used tablet computers for data collection through computer-assisted personal interviewing (CAPI), with questionnaires translated into six major languages for flexibility
• Prior to finalizing survey materials, a pretest briefing was held to discuss survey concepts, field enumeration, and specific instructions for completing questionnaires
• Training of field staff for the NDHS was conducted on two levels: training of the Task Force and training of interviewing teams in the Task Force trainers’ respective regions
• The second level of training for the NDHS took place from April 4 to 26, 2022, in 17 training centers selected by the RSSOs

  
• Trainers in the second-level training were participants in the Task Force training, and the instructors were the 17 regional supervisors and 17 regional IT specialists from each of the 17 regions
• A total of 305 field interviewers and 110 team supervisors were recruited from each of the respective regions to take part in the second-level training
• Fieldwork for the 2022 NDHS was carried out from May 2 to June 22, 2022, by 110 field teams, each consisting of a team supervisor and two to three field interviewers, all female
• Due to the COVID-19 pandemic, guidelines were developed to mitigate potential risks of infection for field teams and survey respondents during data collection, monitoring, and supervision
• Processing of the 2022 NDHS data began almost as soon as fieldwork started, with data files transferred to the PSA Central Office in Quezon City for registration and checking for inconsistencies, incompleteness, and outliers
• Secondary editing of the data involved resolving inconsistencies and recoding "other" responses, with data editing performed using the CSPro software package
• The final cleaning of the data set was carried out by data processing specialists from The DHS Program in September 2022
• Throughout the report, numbers in the tables reflect weighted numbers, with percentages based on fewer than 25 unweighted cases suppressed and replaced with an asterisk
