The dataset is drawn from a scientifically selected sample of census records, designed to ensure national representativeness while preserving respondent confidentiality.\n\nThe PUMS includes information on key variables such as age, sex, marital status, education, economic activity, housing conditions, and household composition, among others. It enables users to explore patterns, relationships, and trends that are not readily available in aggregated census tables. To protect privacy, direct identifiers have been removed and certain data elements modified in accordance with statistical disclosure control standards.\n\nThe dataset is intended for use by researchers, policy analysts, students, and other stakeholders interested in evidence-based planning, academic inquiry, and policy development. Users are advised to consult the accompanying metadata and documentation for proper interpretation and responsible use of the data.","coll_dates":[{"start":"2023-09-24","end":"2023-10-06"}],"nation":[{"name":"Namibia","abbreviation":"NAM"}],"geog_coverage":"National Coverage","analysis_unit":"Households and Individual","universe":"The sampling universe is defined as all households (private and institutions) from 2023 Census dataset.","data_kind":"Census\/enumeration data [cen]","notes":"Identification: Constists of region; constituency; urban and rural\n\nPersons: For all persons in the household\/ institution demographic characteristics, education, labour force \n\n\nHousehold and housing charateristics: Household size; composition; assets; tenure status, material used for the wall, roof and floor; main source of energy; main source of water for cooking and drinking; main toilet facility; main source of income;  and own account agricultural activity."},"method":{"data_collection":{"data_collectors":[{"name":"Namibia Statistics Agency","abbr":"NSA"}],"sampling_procedure":"Sample Design\n\nThe stratified random sample was applied on the constituency and urban\/rural variables of households list from Namibia 2023 Population and Housing Census for the Public Use Microdata Sample (PUMS) file. The sampling universe is defined as all households (private and institutions) from 2023 Census dataset. Since urban and rural are very important factor in the Namibia situation, it was then decided to take the stratum at the constituency and urban\/rural levels. Some constituencies have very lower households in the urban or rural, the office therefore decided for a threshold (low boundary) for sampling within stratum. Based on data analysis, the threshold for stratum of PUMS file is 250  for the 20% sample. Thus, constituency and urban\/rural areas with less than 250 households in total were included in the PUMS file. Otherwise, a simple random sampling (SRS) at a 20%  sampling rate was applied for each stratum. The sampled households include 151,966 housing units and 606,022 persons for the 20% sample.\n\nSample Selection\n\nThe PUMS sample is selected from households. The PUMS sample of persons in households is selected by keeping all persons in PUMS households. Sample selection process is performed using Census and Survey Processing System.\n\nThe smallest geographic unit for PUMS was generated (region + constituency + urban-rural) and a count of households for each one of these geographies was established. A CSPro batch edit was created where two lists of both the geo-unit ids and respective case counts were created (geo-unit id and respective case count maintained the same index within their respective list). \nThe batch edit was written such that, for every new geo-unit, all cases were kept if the case count (from the list) was below the household count threshold and otherwise sampled depending on the size of the sample i.e. every 5th household for 20% sample.","coll_mode":["Computer Assisted Personal Interview [capi]"],"research_instrument":"The following questionnaire instruments were used for the Namibia 2023  Population and and Housing Census:\n\nForm A : For conventional households\nForm B : For institutional Households\nForm C: for special population groups such as Polie holding cells, Homeless, travellers, hospital in-patients, hotels and guesthouses, off-shore populations","sources":[[]],"act_min":"Regional  Census Coordinators: Overseening the 2023 census operations at regional level\n\nDeputy  Regional Census Coordinators: Overseening the 2023  census operations at constituency level\n\nTeam supervisors: Overseening the 2023 census operations at Enumeration Areas and supervised four to five enumerators.\n\nQuality assurance mechanisms\n\nComprehensive quality assurance guidelines were developed and shared with all field personnel. Four layers of fi eld supervision, plus a monitoring team, were put in place to ensure adequate facilitation, real-time response to emerging issues, and feedback to Census Office during data collection. Additionally, Census Monitoring dashbpard was inplace  during enumeration to facilitate real time monitoring activities. \n\nIn addition, since it was CAPI, many control were build in the application to ensure internal constitency of the data.","weight":"The 20% sample had a weight  which was then calibrated to ensure the estimates conform to the total population for the region and sex. The weight variable is appended to the datasets.\n\nThe sample weights were calibrated to align the sample distributions with the full census population totals by region and sex. As a result, estimates produced for this calibrated weight closely match the corresponding census counts.\n\nFor all other variables, however, the estimates are subject to sampling variability because they were not included in the calibration process. Consequently, sample-based estimates may differ from the full census counts, and such differences should be interpreted as an expected outcome of the sampling design rather than as errors in the data.\n\nUsers are therefore advised that while the sample provides reliable estimates of the population, exact agreement with full census figures should only be expected for the variables used in the calibration process (region and sex).","cleaning_operations":"Data entry application was built with many consistency checks, skipping patterns and other validations such as maximum and minimum acceptance range per variable. Supervisors were given minimum variables to check on a day-to-day basis, especially for other - specify (notes) variables. As a result, data consistency checks, coding and validation was done at field level. This minimized the time spent on post data cleaning, validation and editing process. The secondary data cleaning procedures was done using step-by-step instructions developed in CSPRO to verify the structural stability of the published 2023 Census data sets, identify invalid entries and determine the data points that should be subjected to editing or imputation. The above tasks were scripted in CSPRO batch program  were created to automate their accomplishments"}},"data_access":{"dataset_use":{"conf_dec":[{"txt":"Confidentiality of respondents is ensured by Statistics Act No.9, 2011, section 44(2) Before being granted access to the dataset, all users have to formally agree: - Not to use any technique in an attempt to identity any person, establishment, or sampling unit on public use data files. - To hold in strictest confidence the identification of any establishment or individual that may be inadvertently revealed in any documents or discussion, or analysis.
