Demographic and Health Survey [hh/dhs]
The main survey objective of the 2024 ZDHS was:
To provide up-to-date estimates of basic demographic and health indicators necessary for monitoring and evaluating existing health policies and programs in Zambia as well as input data for designing new health initiatives.
Specific objectives of the survey are to:
· Collect high quality data on fertility levels and preferences; contraceptive use; maternal and child health; infant, child and neonatal mortality level; maternal mortality, gender based violence, nutrition, mental health, fistula, HIV and AIDS awareness and other health issues relevant for the Sustainable Development Goals;
· Measure maternal and neonatal morbidity and mortality, and its associated factors (i.e. antenatal and delivery care, pregnancy care, etc.);
· Provide information to address evaluation/monitoring needs of maternal and child health, and family planning programs for evidence-based planning;
· Provide information on availability, access and use of mosquito nets as part of the national malaria eradication programs;
· Collect information on health-related matters such as breastfeeding, maternal and child care (antenatal, during delivery and postnatal), children's immunizations and childhood diseases;
· Assess the nutritional status of mothers and children, including the measurement of anaemia prevalence among women age 15-49 and children 6-59 months, as well as measuring weight and height among children 0-59 months and women age 15-49.
· Measure HIV prevalence levels in men age 15-59, women age 15-49 and children age 2-14, and collect data on behavioural risk factors related to HIV for men and women;
· Assess the circumstances related to violence against women and girls.
· Estimate the seroprevalence of measles among children age 6-59 months. Estimate the seroprevalence of rubella among children age 6-59 months

Sampling
The 2024 ZDHS followed a stratified two-stage sample design. The first stage involved selecting Primary Sampling Units consisting of Enumeration Areas (EAs) from the national sampling frame based on the 2022 Census of Population and Housing. EAs were selected with a probability proportional to their size, measure of size used was the number of households as of the 2022 Census within each EA. A total of 545 clusters were selected.
The second stage involved systematic sampling of households. Prior to this, a household listing operation was undertaken in all of the selected EAs. During the listing, an average of 111 households were found in an EA, from which a fixed number of 25 households were selected through an equal probability systematic selection process, to obtain a total sample size of 13,625 households. Results from this sample are representative at the national, urban and rural, and provincial levels.
All women age 15-49 and men age 15-59 who were either permanent residents of the selected households or visitors who stayed in the households the night before the survey were eligible to be interviewed.
13,625 households were selected for the sample. Of these, 12877 were occupied households and 12808 were successfully interviewed for a response rate of 99%. Within these households, 14362 eligible women age 15-49 were identified for interview, of which 13951 were successfully interviewed (response rate 97%), and 13424 eligible men age15-59 were identified for interview of which 94% were interviewed.
Sample weights were calculated for each of the data files.Sample weights for the household data were computed as the inverse of the probability of selection of the household, computed at the sampling domain level. The household weights were adjusted for non-response at the domain level, and were then normalized by a constant factor so that the total weighted number of households equals the total unweighted number of households. The household weight variable is called HHWEIGHT and is used with the HH data and the HL data.
Sample weights for the women's and men's data used the un-normalized household weights, adjusted for non-response for the women's and man's questionnaire, and were then normalized by a constant factor so that the total weighted number of women's cases equals the total unweighted number of women's cases.
Design weights were adjusted for household nonresponse and as well as for individual non-response to get the sampling weights, for households, women and men surveys respectively. All the nonresponse adjustments will be done at sampling stratum level. The differences between the household sampling weights and the individual sampling weights were introduced by individual non-response. The final sampling weights were normalised in order to give the total number of un-weighted cases equal to the total number of weighted cases at national level, for both household weights and individual weights, respectively. The sampling weights for HIV testing were calculated in a similar way, with correction of nonresponse for both individual survey and for HIV testing, but the normalisation of the sampling weights was different. The HIV testing weights were normalised for male and female together at national level, in order that the HIV prevalence calculated for male and female together are valid. Sampling weights for the domestic violence survey were calculated based on the number of eligible respondents in the households. A total number of six sets of weights were calculated:household; woman; man;women domestic violence; adult HIV testing; HIV testing for children 2-14 years.
Survey instrument
Four questionnaires were used for the 2024 ZDHS: the Household Questionnaire, the Woman's Questionnaire, the Man's Questionnaire, and the Biomarker Questionnaire. The questionnaires, based on The DHS Program's model questionnaires, were adapted to reflect the population and health issues relevant to Zambia. In addition, a self-administered Fieldworker Questionnaire collected information about the survey's fieldworkers. The Household, Man's, and Woman's Questionnaires were administered in eight major languages: English, Bemba, Kaonde, Lozi, Lunda, Luvale, Nyanja, and Tonga.
The Biomarker Questionnaire was used to record the results of anthropometry (height and weight) measurements and haemoglobin and field-based HIV testing for eligible respondents. In addition, the questionnaire was used to record information on specimen collection for lab-based HIV testing for eligible women, men, and children and lab-based testing of antibodies to measles among children.
The Fieldworker Questionnaire collects data on the basic characteristics of fieldworkers and can serve as a
tool in conducting analyses of data quality.

Data collection was carried out from 17 January to 7 July 2024 by 22 teams, each composed of 12 members: one supervisor, three female interviewers, two male interviewers, four biomarker technicians, and two drivers. Fieldwork monitoring was a crucial part of the 2024 ZDHS. Senior technical staff from ZamStats; the Department of Demography, Population Sciences, Monitoring and Evaluation at the
University of Zambia (UNZA); and UTH-VL regularly visited teams to review their work and monitor data quality.
Data processing
The data processing monitors monitored the quality of the data received and downloaded completed data files for completed clusters into the system. ICF provided the CSPro software for data processing and offered technical assistance in the preparation of the data capture, data management, and data editing programmes. Secondary editing was conducted simultaneously with data collection and was completed following data collection.
Data appraisal
Sampling errors for the 2024 ZDHS are calculated for selected variables considered to be of primary interest. The results are presented in this appendix for the country as a whole, for urban and rural areas separately, and for each of the 10 provinces. For each variable, the type of statistic (mean, proportion, or rate) and the base population are given in Table B.1. Tables B.2 through B.14 present the value of the statistic (R), its standard error (SE), the number of unweighted (N) and weighted (WN) cases, the design effect (DEFT), the relative standard error (SE/R), and the 95% confidence limits (R±2SE) for each variable. The sampling errors for mortality rates are presented for the 5-year period preceding the survey for the national sample and the urban and rural samples and for the 10-year period preceding the survey at other domain levels. The DEFT is considered undefined when the standard error considering a simple random sample is zero (when the estimate is close to 0 or 1).
