The updated list of enumeration areas (EAs) for the 2010 Population and Housing Census provided the sampling frame for the survey. The frame comprises 25,631 EAs and 2,815,897 households. An EA is a convenient geographical area with an average size of 130 households or 600 people.  A representative sample of 18,052 households was drawn for the 2013-14 ZDHS. The survey used a two-stage stratified cluster sample design, with EAs (or clusters) selected during the first stage and households selected during the second stage. In the first stage, 722 EAs (305 in urban areas and 417 in rural areas) were selected with probability proportional to size. Zambia is now administratively divided into 10 provinces (Central, Copperbelt, Eastern, Luapula, Lusaka, Muchinga,2 Northern, North Western, Southern, and Western). Stratification was achieved by separating each province into urban and rural areas. Therefore, the 10 provinces were stratified into 20 sampling strata. In the second stage, a complete list of households served as the sampling frame in the selection of households for enumeration. An average of 25 households was selected in each EA. It was during the second stage of selection that a representative sample of 18,052 households was selected.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"Three questionnaires were used in the 2013-14 ZDHS: the Household Questionnaire, the Woman\u2019s Questionnaire, and the Man\u2019s Questionnaire. The three instruments were based on the questionnaires developed by the Demographic and Health Surveys Program and adapted to Zambia\u2019s specific data needs. The questionnaires were translated into seven major languages: Bemba, Kaonde, Lozi,Lunda, Luvale, Nyanja, and Tonga. Questionnaires and field procedures were pretested prior to implementation of the main survey.\nThe Household Questionnaire was used to collect data such as:\n   \u2022 Age, sex, marital status, and education of all usual members and visitors\n   \u2022 Current school attendance and survivorship of parents among children under age 18\n   \u2022 Characteristics of the structural dwelling\/housing unit\n   \u2022 Sanitation facilities and source of water\n   \u2022 Ownership of durable goods, land, and livestock\n   \u2022 Ownership and use of mosquito nets\n   \nThe Household Questionnaire was also used to record biomarker data, including height and weight\ndata for children and women and HIV and CD4 testing information for women and men.

The differences in the household sampling weight and the individual sampling weights were introduced by individual non-response. The final sampling weights were normalised to get the total number of unweighted cases equal to the total number of weighted cases at the national level, for both household and individual weights. The normalised weights were relative weights that were valid for estimating means, proportions, and ratios but not valid for estimating population totals and pooled data.","method_notes":"All questionnaires for the 2013-14 ZDHS were returned to the CSO headquarters in Lusaka for data processing, which consisted of office editing, coding of open-ended questions, data entry, and editing of computer-identified errors. Data processing staff included two data processing supervisors, 24 data entry\nclerks, five office editors, four secondary editors, one questionnaire administrator, and one biomarker\nadministrator.\n\nThe processing of the data began in September 2013, one month after data collection commenced, and continued concurrently with the fieldwork. This offered an advantage because data were consistently checked and feedback was given to field teams, thereby improving data quality. Before being sent to the data processing centre in Lusaka, completed questionnaires were edited in the field by the field editors and checked by the supervisors. At the processing centre, data were edited and coded by office editors. Data were then entered using the CSPro computer package. All data were entered twice for 100 percent verification. This double entry of data enabled easy comparisons and identification of errors and inconsistencies. Inconsistencies were resolved by tallying the data with the paper questionnaire entries.\n\nFurther inconsistencies that were identified were resolved through secondary editing of the data. The data\nfiles (excluding HIV testing data) were finalised in June 2014 after data cleaning."},"analysis_info":{"response_rate":"A total of 18,052 households were selected from 722 clusters, of which 16,258 were occupied at the time of the fieldwork.

Therefore, to obtain the 95 percent confidence limits, one adds and subtracts twice the standard error to the sample estimate, i.e., 6.341 \u00b1 2\u00d70.077. There is a high probability (95 percent) that the true proportion of women 40-49 with children ever born is between 6.187 and 6.496. For the total sample, the value of the DEFT, averaged over all variables, is 1.490. This means that, due to multi-stage clustering of the sample, the average standard error is increased by a factor of 1.490 over that in an equivalent simple random sample."}},"data_access":{"dataset_use":{"conf_dec":[{"txt":"The Agency shall,where statistics are designated as official statistics, protect the confidentiality and identity of the source of data.\n\nUnder the provision of the Statistics ACT no.13 of 2018, ZamStats is obliged to preserve the confidentiality of respondent information in all its census and survey data\n\nBefore being granted access to the dataset, all users have to formally agree: \n   1.
