It has been conducted for more than twenty years, with its first round conducted in July 2002, and it was originally designed to meet user need of a survey conducted regularly to measure the level of development and the performance of government programs and projects."},"study_info":{"abstract":"The General Household Survey is an annual household survey measuring the living conditions of households in South Africa.

This Master Sample has design requirements that are reasonably compatible with the General Household Survey. The 2013 Master Sample is based on information collected during the Census 2011 conducted by Statistics South Africa. \n\nIn preparation for the Census 2011, the country was divided into 103 576 enumeration areas (EAs). The census EAs, together with the auxiliary information for the EAs, were used as the frame units or building blocks for the formation of primary sampling units (PSUs) for the Master Sample, since they covered the entire country, and had other information that is crucial for stratification and creation of PSUs. There are 3324 PSUs in the Master Sample, with an expected sample of approximately 33 000 dwelling units (DUs). The number of PSUs in the current Master Sample (3324) reflects an 8.0 percent increase in the size of the Master Sample compared to the previous: the 2008 Master Sample had 3080 PSUs. \n\nThe larger Master Sample was selected to improve the precision (resulting in smaller coefficients of variation, known as CVs) of the General Household Survey estimates. The Master Sample is designed to provide survey estimates that are representative at provincial level, and within provinces, at metro\/non-metro levels. Within the metros, the sample is further distributed by geographical type. The three geography types are Urban, Tribal and Farms. This implies, for example, that within a metropolitan area, the sample is representative of the different geography types that may exist within that metro.\n\nThe sample for the General Household Survey is based on a stratified two-stage design with probability proportional to size (PPS) sampling of PSUs in the first stage, and sampling of DUs with systematic sampling in the second stage. After allocating the sample to the provinces, the sample was further stratified by geography (primary stratification), and by population attributes using Census 2011 data (secondary stratification).","coll_mode":["Computer Assisted Personal Interview [capi]"],"research_instrument":"Data was collected with a household questionnaire and a questionnaire administered to a household member to elicit information on household members.","coll_situation":"Due to the COVID-19 Pandemic, Statistics South Africa changed the mode of collecting General Household Survey 2020 data from Computer Assisted Personal Interviews (CAPI) to Computer-assisted Telephone Interviews (CATI). After the pandemic, in 2022, the General Household Survey reintroduced the CAPI interviews.","weight":"Sample weights were constructed in order to account for the following: \n- the original selection probabilities (design weights)\n- adjustments for PSUs that were sub-sampled or segmented\n- population excluded from the sampling frame\n- non-response\n- weight trimming\n- benchmarking to known population estimates from the Demographic Analysis Division within Statistics South Africa \n\nSampling weights for the data collected from sampled households were constructed so that the responses could be properly expanded to represent the entire civilian population of South Africa. Design weights, which are the inverse sampling rate (ISR) for the province, were assigned to each of the households in a province.\n\nMid-year population estimates, produced by the Demographic Analysis Division, were used for benchmarking. Final survey weights were constructed using regression estimation to calibrate to national level population estimates cross-classified by 5-year age groups, gender and race, and provincial population estimates by broad age groups. The 5-year age groups were: 0-4, 5-9, 10-14, 55-59, 60-64, and 65 and over. The provincial level age groups were: 0-14, 15-34, 35-64, and 65 years and over. The calibrated weights were constructed such that all persons in a household would have the same final weight.\n\nNote on Independently Calibrated Weights for the Person and Household Data Files:\nUntil 2010 Statistics South Africa used an integrating weighting methodology. \"Integrated\" weights allocated the same weight to all household members. The household head's weight was carried over the house file. This model allowed the replication of the population size if household sizes were multiplied with the household weight. However, this method provided variable household totals from year to year. Therefore, from 2010, the Person and House files across the whole GHS series are calibrated independently from each other. The person data is calibrated using the mid-year population estimates from the 2017 series, while the house data is weighted using household estimates that are also based on the 2017 mid-year population series. However, this method means that the totals will not be aligned. For weights that are better aligned, users can transfer the weight allocated to the household head to the household file. Statistics South Africa ensures that all households in the house file are also represented in the person file."},"analysis_info":{"data_appraisal":"Since 2019, the questionnaire for the GHS series changed and the variables were also renamed.
