Administratively, Tajikistan is divided into five administrative regions: Dushanbe City, Districts of Republican Subordination (DRS), Sughd, Khatlon, and Gorno-Badakhshan Autonomous Oblast (GBAO). Each region is subdivided into urban and rural areas. The country is divided into 68 cities and rayons (districts) distributed over the country\u2019s regions. Each city or rayon (district) is further divided into census divisions, which are subdivided into instruction areas. Each instruction area is divided into enumeration areas (EAs).\n\nThe 2023 TjDHS followed a stratified two-stage sample design. The first stage involved selecting sample points (clusters) consisting of EAs. EAs were drawn with a probability proportional to their size within each sampling stratum. A total of 370 clusters were selected, 166 in urban areas and 204 in rural areas. The second stage involved systematic sampling of households. A household listing operation was undertaken in all of the selected clusters, and a fixed number of 22 households per cluster were selected through an equal probability systematic selection process, for a total sample size of approximately 8,140 households.\n\nAll women age 15-49 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. Hemoglobin testing was performed in each household among eligible women age 15-49 who consented to being tested. With the parent\u2019s or guardian\u2019s consent, children age 6-59 months were also tested for anemia in each household. Height and weight information was collected from eligible women age 15-49 and children age 0-59 months in all households. Also, one eligible woman in each household was randomly selected to be asked additional questions about domestic violence.\n\nFor further details on sample design, see APPENDIX A of the final report.","research_instrument":"Three questionnaires were used in the 2023 TjDHS: the Household Questionnaire, the Woman\u2019s Questionnaire, and the Biomarker Questionnaire. The questionnaires, based on The DHS Program\u2019s model questionnaires, were adapted to reflect the population and health issues relevant to Tajikistan. Suggestions were solicited from various stakeholders representing government ministries and agencies, nongovernmental organizations, and international donors. After all questionnaires were finalized in English, they were translated into Russian and Tajik.","coll_mode":["Face-to-face computer-assisted interviews [capi]"],"coll_situation":"Data collection was carried out by 15 field teams, each consisting of one female team supervisor, four female interviewers, and two health investigators (at least one of whom was female and at least one of whom was standardized for anthropometry). Fieldwork started in most regions on August 10, 2023, and ended on November 28, 2023.\n\nFieldwork monitoring was an integral part of the 2023 TjDHS. Senior TjDHS technical staff from Tajstat, along with three DHS quality control field monitors, three biomarker quality control field monitors, five field coordinators, and four CAPI coordinators, visited teams regularly to review work and monitor data quality. Also, representatives from The DHS Program visited teams to monitor data collection and to observe anemia testing and height and weight measurements of women and children under age 5. During field visits, staff provided teams (supervisor, interviewers, and health investigators) with critical feedback to improve their performance. In addition, they used TjDHS field-check tables based on data from completed clusters to illustrate problems specific to each team visited. Field-check tables based on the completed questionnaires entered during fieldwork were generated in real time as fieldwork progressed and were available online via the SyncCloud platform. The tables were reviewed and discussed with the Tajstat staff on an ongoing basis to alert field teams to data quality issues found during the survey fieldwork and to ensure that quality data collection was maintained throughout the fieldwork.","cleaning_operations":"The 2023 TjDHS used a Windows-based system. All electronic data files were transferred via a secure SyncCloud server to the Tajstat central office in Dushanbe, where they were stored on a password-protected computer. The data processing operation included secondary editing, which required resolution of computer-identified inconsistencies and coding of open-ended questions. The data were processed by five IT specialists\/secondary editors who took part in the main fieldwork training, the training of trainers, and a refresher secondary editing training session; they were supervised remotely by staff from The DHS Program. Data editing was accomplished using CSPro software. Secondary editing and data processing were initiated in December 2023 and completed in February 2024.","data_collectors":[{"name":"Agency on Statistics under the President of the Republic of Tajikistan","abbr":"Tajstat","affiliation":"Government of Tajikistan"}],"weight":"A spreadsheet containing all sampling parameters and selection probabilities was prepared to help calculate the design weights. Design weights were adjusted for household nonresponse and individual nonresponse to obtain the sampling weights for households and for women. Nonresponse was adjusted at the sampling stratum level. For household sampling weights, household design weights were multiplied by the inverse of household response rates according to stratum. For women\u2019s individual sampling weights, household sampling weights were multiplied by the inverse of women\u2019s individual response rates according to stratum. After adjustment for nonresponse, the sampling weights were normalized (by multiplying the sampling weight by the estimated total sampling fraction obtained from the survey for the household weight and the woman\u2019s weight) to obtain the final standard weights that appear in the data files. The normalization process was done so that the total number of unweighted cases was equal to the total number of weighted cases at the national level for both households and women. The normalized weights are relative weights that are valid for estimating means, proportions, ratios, and rates but are not valid for estimations based on pooled data or for estimating population totals.\n\nFor further details on sample weights, see APPENDIX A.4 of the final report."},"analysis_info":{"response_rate":"A total of 8,140 households were selected for the TjDHS sample, of which 8,070 were found to be occupied. Of the occupied households, 8,035 were successfully interviewed, yielding a response rate of over 99%. In the interviewed households, 9,930 women age 15-49 were identified as eligible for individual interviews. Interviews were completed with 9,879 women, yielding a response rate of over 99%.","sampling_error_estimates":"The estimates from a sample survey are affected by two types of errors: non-sampling errors and sampling errors. Non-sampling errors are the results of mistakes made in implementing data collection and data processing, such as failure to locate and interview the correct household, misunderstanding of the questions on the part of either the interviewer or the respondent, and data entry errors. Although numerous efforts were made during the implementation of the 2023 Tajikistan Demographic and Health Survey (2023 TjDHS) to minimize this type of error, non-sampling errors are impossible to avoid and difficult to evaluate statistically.\n\nSampling errors, on the other hand, can be evaluated statistically. The sample of respondents selected in the 2023 TjDHS is only one of many samples that could have been selected from the same population, using the same design and sample size. Each of these samples would yield results that differ somewhat from the results of the actual sample selected. Sampling errors are a measure of the variability among all possible samples. Although the degree of variability is not known exactly, it can be estimated from the survey results.\n\nSampling error is usually measured in terms of the standard error for a particular statistic (mean, percentage, etc.), which is the square root of the variance. The standard error can be used to calculate confidence intervals within which the true value for the population can reasonably be assumed to fall. For example, for any given statistic calculated from a sample survey, the value of that statistic will fall within a range of plus or minus two times the standard error of that statistic in 95% of all possible samples of identical size and design.\n\nIf the sample of respondents had been selected by simple random sampling, it would have been possible to use straightforward formulas for calculating sampling errors. However, the 2023 TjDHS sample was the result of a multistage stratified cluster design, and, consequently, it was necessary to use more complex formulas. Sampling errors are computed in SAS programs developed by ICF. These programs use the Taylor linearization method to estimate variances for survey estimates that are means, proportions, or ratios. The Jackknife repeated replication method is used for variance estimation of more complex statistics such as fertility and mortality rates.\n\nA more detailed description of estimates of sampling errors are presented in APPENDIX B of the survey report.","data_appraisal":"Data Quality Tables\n- Household age distribution\n- Age distribution of eligible and interviewed women\n- Age displacement at age 14\/15\n- Age displacement at age 49\/50\n- Pregnancy outcomes by years preceding the survey\n- Completeness of reporting\n- Standardization exercise results from anthropometry training\n- Height and weight data completeness and quality for children\n- Height measurements from random subsample of measured children\n- Interference in height and weight measurements of children\n- Interference in height and weight measurements of women\n- Heaping in anthropometric measurements for children (digit preference)\n- Observation of handwashing facility\n- School attendance by single year of age\n- Vaccination cards photographed\n- Prevalence of anemia in children based on 2011 WHO guidelines\n- Prevalence of anemia in women based on 2011 WHO guidelines\n- Population pyramid\n- Five-year mortality rates\nSee details of the data quality tables in Appendix C of the final report."}},"data_access":{"dataset_availability":{"access_place":"The DHS Program","access_place_url":"https:\/\/www.dhsprogram.com\/data\/available-datasets.cfm"},"dataset_use":{"contact":[{"name":"The DHS Program","uri":"https:\/\/dhsprogram.com"}],"conditions":"Request Dataset Access\nThe following applies to DHS, MIS, AIS and SPA survey datasets (Surveys, GPS, and HIV).\nTo request dataset access, you must first be a registered user of the website.
