The sample size for the QLFS is roughly 30 000 dwellings per quarter.\n\nThe sample is based on information collected during the 2001 Population Census conducted by Stats SA. In preparation for the 2001 Census, the country was divided into 80 787 enumeration areas (EAs). Stats SA's household-based surveys use a Master Sample of Primary Sampling Units (PSUs) which comprises of EAs that are drawn from across the country.\n\nThe sample is designed to be representative at the provincial level and within provinces at the metro\/non-metro level. Within the metros, the sample is further distributed by geography type. The four geography types are: urban formal, urban informal, farms and tribal. This implies, for example, that within a metropolitan area the sample is representative at the different geography types that may exist within that metro.\n\nThe current sample size is 3 080 PSUs. It is divided equally into four sub-groups or panels called rotation groups. The rotation groups are designed in such a way that each of these groups has the same distribution pattern as that which is observed in the whole sample. They are numbered from one to four and these numbers also correspond to the quarters of the year in which the sample will be rotated for the particular group.\n\nThe sample for the QLFS is based on a stratified two-stage design with probability proportional to size (PPS) sampling of primary sampling units (PSUs) in the first stage, and sampling of dwelling units (DUs) with systematic sampling in the second stage.","coll_mode":"Face-to-face [f2f]","weight":"Stats SA updated the QLFS results (2008-2013) to reflect the new population benchmarks from Census 2011. Although the weighting changes are not clearly documented by Stats SA, users are advised to remain aware of these slight calibration differences between the previous version and the current (revised) data version when employing weights.\n\nThe sampling weights for the data collected from the sampled households are constructed in such a manner that the responses could be properly expanded to represent the entire civilian population of South Africa. The weights are the result of calculations involving several factors, including original selection probabilities, adjustment for non-response, and benchmarking to known population estimates from the Demographic division of Stats SA.\n\nThe final survey weights are constructed using regression estimation to calibrate to the known population counts at the national level population estimates (which are supplied by the Demography division) crossclassified by 5-year age groups, gender and race, and provincial population estimates by broad age groups. The 5-year age groups are: 0\u20134, 5\u20139, 10\u201314, etc., and 65 years and over. The provincial-level age groups are: 0\u201314, 15\u201334, 35\u201364, and 65 years and over. The calibrated weights are constructed such that all persons in a household would have the same final weight."},"analysis_info":{"response_rate":"Response rates by province\nProvince Jan\u2013Mar 2012 (Percent)\nWestern Cape 84.2\nEastern Cape 97.8\nNorthern Cape 91.2\nFree State 96.4\nKwaZulu-Natal 97.4\nNorth West 93.2\nGauteng 84.1\nMpumalanga 95.2\nLimpopo 98.8\nSouth Africa 92.6","sampling_error_estimates":"Because estimates are based on sample data, they differ from figures that would have been obtained from complete enumeration of the population using the same instrument. Results are subject to both sampling and non-sampling errors. Non-sampling errors include biases from inaccurate reporting, processing, and tabulation, etc., as well as errors from non-response and incomplete reporting. These types of errors cannot be measured readily. However, to the extent possible, non-sampling errors can be minimised through the procedures used for data collection, editing, quality control, and non-response adjustment. The variances of the survey estimates are used to measure sampling errors."}},"data_access":{"dataset_use":{"contact":[{"name":"DataFirst","affiliation":"University of Cape Town","email":"support@data1st.org","uri":"http:\/\/www.datafirst.uct.ac.za"}],"cit_req":"Use of the dataset must be acknowledged using a citation which would include:\n- Identification of the Primary Investigator,\n- Title of the survey (including country, acronym and year of implementation),\n- Survey reference number,\n- Source and date of download.\n\nExample:\nStatistics South Africa.
