The Community Survey is designed to provide information on the trends and levels of demographic and socio-economic data, such as population size and distribution; the extent of poor households; access to facilities and services, and the levels of employment\/unemployment at national, provincial and municipality level. The data can be used to assist government and the private sector in the planning, evaluation and monitoring of programmes and policies. The information collected can also be used to assess the impact of socio-economic policies and provide an indication as to how far the country has gone in its strides to eradicate poverty.\n\nCensuses 1996 and 2001 are the only all-inclusive censuses that Statistics South Africa has thus far conducted under the new democratic dispensation. Demographic and socio-economic data were collected and the results have enabled government and all other users of this information to make informed decisions. When cabinet took a decision that Stats SA should not conduct a census in 2006, it created a gap in information or data between Census 2001 and the next Census scheduled to be carried out in 2011. A decision was therefore taken to carry out the Community Survey in 2007.\n\nThe main objectives of the survey were:\n\u00b7\tTo provide estimates at lower geographical levels than existing household surveys;\n\u00b7\tTo build human, management and logistical capacities for Census 2011; and\n\u00b7\tTo provide inputs into the preparation of the mid-year population projections.\n\nThe wider project strategic theme is to provide relevant statistical information that meets user needs and aspirations. Some of the main topics that are covered by the survey include demography, migration, disability and social grants, educational levels, employment and economic activities.","coll_dates":[{"start":"2007-02","end":"2007-03","cycle":""}],"nation":[{"name":"South Africa","abbreviation":"ZAF"}],"geog_coverage":"The survey covered the whole of South Africa, including all nine provinces as well as the four settlement types - urban-formal, urban-informal, rural-formal (commercial farms) and rural-informal (tribal areas).","analysis_unit":"Households","universe":"The Community Survey covered all de jure household members (usual residents) in South Africa.  The survey excluded collective living quarters (institutions) and some households in EAs classified as recreational areas or institutions. However, an approximation of the out-of-scope population was made from the 2001 Census and added to the final estimates of the CS 2007 results.","data_kind":"Sample survey data [ssd]","notes":"The scope of the Community Survey (CS) includes:\n\nDemographic characteristics (age and sex, population group, fertility, mortality), migration, economic activity, geographical distribution, marital status, disability, education, household good, access to services (social security services, housing, water, energy, sanitation, communication services, refuse removal)."},"method":{"data_collection":{"data_collectors":[{"name":"Statistics South Africa","abbreviation":"SSA","affiliation":""}],"sampling_procedure":"Sample Design\n\nThe sampling procedure that was adopted for the CS was a two-stage stratified random sampling process.  Stage one involved the selection of enumeration\nareas, and stage tow was the selection of dwelling units.\n\nSince the data are required for each local municipality, each municipality was considered as an explicit stratum. The stratification is done for those municipalities classified as category B municipalities (local municipalities) and category A municipalities (metropolitan areas) as proclaimed at the time of Census 2001. However, the newly proclaimed boundaries as well as any other higher level of geography such as province or district municipality, were considered as any other domain variable based on their link to the smallest geographic unit - the enumeration area.\n\n The Frame\n \nThe Census 2001 enumeration areas were used because they give a full geographic coverage of the country without any overlap. Although changes in settlement type, growth or movement of people have occurred, the enumeration areas assisted in getting a spatial comparison over time. Out of 80 787 enumeration areas countrywide, 79 466 were considered in the frame. A total of 1 321 enumeration areas were excluded (919 covering institutions and 402 recreational areas).\n\nOn the second level, the listing exercise yielded the dwelling frame which facilitated the selection of dwellings to be visited. The dwelling unit is a structure or part of a structure or group of structures occupied or meant to be occupied by one or more households. Some of these structures may be vacant and\/or under construction, but can be lived in at the time of the survey. A dwelling unit may also be within collective\nliving quarters where applicable (examples of each are a house, a group of huts, a flat, hostels, etc.).   \n\nThe Community Survey universe at the second-level frame is dependent on whether the different structures are classified as dwelling units (DUs) or not. Structures where people stay\/live were listed and classified as dwelling units. However, there are special cases of collective living quarters that were also included in the CS frame. These are religious institutions such as convents or monasteries, and guesthouses where people stay for an extended period (more than a month). Student residences - based on how long people have stayed (more than a month) - and old-age homes not similar to hospitals (where people are living in a communal set-up) were treated the same as hostels, thereby listing either the bed or room. In addition, any other family staying in separate quarters within the premises of an institution (like wardens' quarters, military family quarters, teachers' quarters and medical staff quarters) were considered as part of the CS frame. The inclusion of such group quarters in the frame is based on the living circumstances within these structures. Members are independent of each other with the exception that they sleep under one roof. \n\nThe remaining group quarters were excluded from the CS frame because they are difficult to access and have no stable composition. Excluded dwelling types were prisons, hotels, hospitals, military barracks, etc. This is in addition to the exclusion on first level of the enumeration areas (EAs) classified as institutions (military bases) or recreational areas (national parks).\n\nThe Selection of Enumeration Areas (EAs)\n\nThe EAs within each municipality were ordered by geographic type and EA type. The selection was done by using systematic random sampling. The criteria used were as follows:\nIn municipalities with fewer than 30 EAs, all EAs were automatically selected.\nIn municipalities with 30 or more EAs, the sample selection used a fixed proportion of 19% of all sampled EAs. However, if the selected EAs in a municipality were less than 30 EAs, the sample in the municipality was increased to 30 EAs.\n\nThe Selection of Dwelling Units\n\nThe second level of the frame required a full re-listing of dwelling units. The listing exercise was undertaken before the selection of DUs. The adopted listing methodology ensured that the listing route was determined by the lister. Thisapproach facilitated the serpentine selection of dwelling units. The listing exercise provided a complete list of dwelling units in the selected EAs. Only those structures that were classified as dwelling units were considered for selection, whether vacant or occupied. This exercise yielded a total of 2 511 314 dwelling units.\n\nThe selection of the dwelling units was also based on a fixed proportion of 10% of the total listed dwellings in an EA. A constraint was imposed on small-size EAs where, if the listed dwelling units were less than 10 dwellings, the selection was increased to 10 dwelling units. All households within the selected dwelling units were covered. There was no replacement of refusals, vacant dwellings or non-contacts owing to\ntheir impact on the probability of selection.","coll_mode":"Face-to-face [f2f]","research_instrument":"Consultation on Questionnaire Design\nTen stakeholder workshops were held across the country during August and September 2004. Approximately 367 stakeholders, predominantly from national, provincial and local government departments, as well as from research and educational institutions, attended. The workshops aimed to achieve two objectives, namely to better understand the type of information stakeholders need to meet their objectives, and to consider the proposed data items to be included in future household surveys. The output from this process was a set of data items relating to a\nspecific, defined focus area and outcomes that culminated with the data collection instrument (see Annexure B for all the data items).\n\nQuestionnaire Design\nThe design of the CS questionnaire was household-based and intended to collect information on 10 people. It was developed in line with the household-based survey questionnaires conducted by Stats SA. The questions were based on the data items generated out of the consultation process described above. Both the design and questionnaire layout were pre-tested in October 2005 and adjustments were made\nfor the pilot in February 2006. Further adjustments were done after the pilot results had been finalised.","coll_situation":"Training of Fieldworkers\n\nTraining was planned and executed at national, provincial and district levels. The trainees at national level did the training at provincial level, and those that were trained at provincial level did the training at district level. The cascade method of training was at three levels. Training was initiated by subject matter specialists training the trainers at Head Office. The national trainers trained Provincial Survey Coordinators (PSCs), District Survey Coordinators (DSCs), Mapping Monitors (MMs) and GIS Officers at national level. The DSCs trained Fieldwork Coordinators (FWCs) at provincial level with the supervision and monitoring of the PSCs and Head Office monitors. Finally, FWCs trained Fieldwork\nSupervisors (FWSs) and Enumerators at district level.\n\nDuring the training of fieldworkers, video training technology was used in addition to the instructor-led training approach. Although video training can never replace the trainer completely, it offered an ideal opportunity to access large numbers of trainees, in different training venues, at different times, with customised training solutions, quickly and cost effectively. After facilitation by the trainer during training sessions, a training video was used to consolidate knowledge learnt and to clarify issues that were not clear to trainees during training.\n\nEvery training session was evaluated by both the trainees and trainers. Trainers completed a daily evaluation form in order to identify problems that trainees had experienced during that particular day\u2019s training. Areas that needed remedial training were revisited the following day.\n\nEnumeration\n\nThe main objective of enumeration is to collect and document particulars of all individuals and housing units with the selected respondent(s).\nThe adopted enumeration method for CS 2007 was canvassing, whereby the enumerator conducts a face-to-face interview with the respondent while simultaneously completing the questionnaire. The Community Survey adopted both the de jure and de facto approach in order to compare with other Stats SA social statistics definitions as well as to give a comparison over time between the censuses with the ultimate objective of having two estimates of the population \u2013 the de jure population estimates are mostly useful for long-term planning, and the de facto\npopulation estimates are mostly used for demographic estimations. \n\nEnumerators visited the selected sampled dwelling units to interview households and ensure that the information required from them was captured on the questionnaires. Self-enumeration was not allowed. The enumeration was carried out over a three week period with a non-response follow-up period of one week as planned, that is on 7 February 2007. The mop-up exercise was carried out from 1 to 7 March. This\nincluded follow-up on non-contacts, vacant dwellings, and unoccupied dwellings. However, due to the high number of dwelling units that were being mapped for the non- response follow-up period, the contracts of enumerators were extended beyond 28 February to assist the supervisors during that period. \n\nQuality Assurance\n\nThe FWS and FWC conducted 100% quality checks for accuracy and completeness on all completed questionnaires. In addition, the DSCs, PSCs and Monitors also did quality checks on randomly selected questionnaires and DUs and addressed problematic questions as they came up. In addition, the FWC did 2% spot checks of selected dwelling units within their assigned fieldwork coordination unit to minimise\nbogus enumeration. Training played a big role in ensuring good quality data from the field. At district level, retraining was done in areas where fieldwork monitors felt that the work was not of the expected quality. A close watch was also kept on individual enumerators, and Fieldwork Supervisors and Fieldwork Coordinators who had problems performing according to expectations were retrained where necessary. Their work was also checked more frequently.\n\nFWS were required to package questionnaires in their EA boxes and hand them over to the FWCs soon after the completion of the EA. The FWCs were required to sign for the receipt of the boxes after verifying the contents of the boxes. They were in turn required to hand over the completed boxes to the DLOs for reverse logistics. DLOs were also required to sign for the receipt of the boxes after verifying the contents of the boxes. The boxes were then stored in designed storage areas awaiting shipping back to the data processing centre in Pretoria.\n\nProgress reporting for data collection was done on a daily basis. Provinces were provided with procedures and timelines for progress reporting and were able to report progress on a daily basis though at the initial stages, there were problems as outlined below.\n\nThe Pilot Survey\n\nA pilot survey was conducted in February 2006. The purpose of the pilot was to test all the developed strategies, methodologies, systems, and the questionnaire. A total of 782 EAs were covered in the pilot survey.  During the pilot survey the effectiveness of instruments, processes and methods used within the scope of the CS were tested. A range of lessons were learnt which led to the refinement of processes, methods and systems towards the main survey.","act_min":"Supervision\n\nThe data collection approach revolved around the use of a mobile team of four enumerators and a supervisor. The team was assigned a fixed number of EAs to enumerate. The team worked together in each sampled EA and moved to the next one once the targeted EA had been completed. The advantage of this method was that the supervisor was in daily contact with the team, which improved the quality of\nthe data collected during fieldwork. During enumeration, supervisors (who doubled up as drivers) and their teams of four\nenumerators each, identified the selected EA. They then dropped off each enumerator at a selected dwelling unit, and ascertained that each enumerator had been accepted to conduct the interview. They picked up the enumerator who had completed the interview and immediately checked the questionnaire for errors, consistency and completeness. Where errors were found, the enumerator was sent back to the household to correct the information that had been recorded. If the supervisors were satisfied, they signed off the questionnaire and stored it in a safe place. Supervisors did the same for all the members of their teams until the EA had been completed. The team then moved to another selected EA.\n\nBased on the number of sampled EAs (17 098), 1 182 teams comprising 1 182 Fieldwork Supervisors and 4 728 enumerators were formed. Each team was expected to enumerate about 16-20 EAs in three weeks, with an additional one week assigned for non-contacts and refusals. The supervisors were supervised by 236 Fieldwork Coordinators (FWCs), resulting in a Fieldwork Coordinator-to-Supervisor ratio of 1:5. Fieldwork Coordinators were supervised by 55 District Survey Coordinators (DSCs), resulting in a DSC-to-FWC ratio of 1:4. The DSCs were\nsupervised by nine Provincial Survey Coordinators (PSCs), resulting in a PSC-to-DSC ratio of approximately 1:6. The PSCs were based in their respective provincial offices. They coordinated data collection for their assigned province. The 55 DSCs were based in 55 district offices (DOs) that were temporarily created specifically for CS 2007. Each of the 236 FWCs had a temporary local office or fieldwork station that was used as a base during the fieldwork phase of the project, and also for the training of enumerators and supervisors attached to them.","weight":"The Weights Calculation\n \nThe Community Survey sample has equal probabilities for all elements in the cluster which make it a self-weighting systematic random sample. Since the sample is stratified by municipalities as demarcated at the time of Census 2001, the inclusion probability of selection of an EA at the first level of selection, and the dwelling unit at the second level of selection, is the product of first and second-level probabilities. Also, since all households within the dwelling unit are considered, their probability of being in the dwelling unit is always one.","cleaning_operations":"Editing\nThe automated cleaning was implemented based on an editing rules specification defined with reference to the approved questionnaire. Most of the editing rules were categorised into structural edits looking into the relationship between different record type, the minimum processability rules that removed false positive readings or noise, the logical editing that determine the inconsistency between fields of the same statistical unit, and the inferential editing that search similarities across the domain.  The edit specifications document for the structural, population, mortality and housing edits was developed by a team of Stats SA subject-matter specialists, demographers, and programmers. The process was successfully carried out during the months of July\/August 2007.","method_notes":"Data Processing\n\nData processing refers to a class of programmes that organise and manipulate usually large amounts of numeric data. Data processing involved the processing of completed questionnaires. Information received from questionnaires collected during fieldwork was converted into data represented by numbers or characters. The two methods used for this conversion were manual capturing (key-entry) and scanning. The scanning method was used as the main process and the key-entry application was used for questionnaires that were damaged and not scannable.\n\nHigh-Level Processes\nIn general, the high-level processes covered the following activities:\nBoxes were received and questionnaires were checked to ensure that:\n1) they belonged to the box; and\n2) were not damaged.\nData were then captured and converted into electronic format through scanning or Key-from-Paper (KFP). Thereafter, an account of all sampled dwelling units was prepared and data were balanced to verify whether the data collected for each household contained the four sections \u2013 General, Persons, Mortality, and Household.\nData were then checked for consistency and prepared for final output based on the tabulation plan.\n\nData Capturing\n\nTwo methods were used for capturing the data, namely scanning and manual capturing (key-entry).\n\nScanning\nThe scanning process proceeded as follows:\nThe data processor scanned the box number, and then entered the estimated number of pages in each batch. At this stage, the batches were ready to be scanned. One box at a time was given to each of the six Scanning Operators to avoid scanning the questionnaires twice. The batches were then taken out of the box and placed next to the tray on the scanner. The box number was then scanned using the small hand-held scanner and the number of pages per batch was entered into the Input Station.\n\nA visual check was performed on the scanning to ensure that the images were clear of any noise and that the data were clear and readable. The barcode as well as the actual data on the questionnaire was checked. In the case where the image was either too light or too dark, parameters were adjusted and the batch was rescanned. Validations were automatically executed to confirm scanning parameters and image\nquality. Questionnaires that could not be scanned were de-activated from their boxes and assigned to a new box. Images were transferred to the server and their barcodes were tracked. These questionnaires were then sent to Key-from-Paper.\n\nManual Capturing (Key-from-Paper)\nKey-from-Paper (KFP) is an application for manual data capturing. The application was developed to capture questionnaires that were not suitable for scanning. Such questionnaires included those which were torn or where pencil entries were not bold enough for the interpretation of the scanner, or those that were in a bad condition. Duplicate application was created for quality assurance purposes. The same questionnaires that were captured in application one, were also captured on application two. Each questionnaire captured in both applications, was compared to one another using corresponding fields. Validation checks were not implemented in the applications. The application was used by data processors to capture information as was reflected on the questionnaires. EA and DU numbers were placed into the look-up table to validate the sampled frame. In cases where an EA or DU was found to be invalid, the EA Summary Book was then used for corrections.\n\nCoding of Open-Ended Questions\nCoding is the process of assigning numerical values to responses to facilitate data capturing and processing in general. The code lists for occupation and industry were based on the International Standard Classifications done to the five-digit level. The variables covered were occupation, industry, and place names."},"analysis_info":{"response_rate":"Community Survey 2007 Response Rates\n\nTotal number of dwelling units - 274 348 dwelling units\nCompleted cases responding - 238 067 dwelling units (93,9%)\nNon-response cases - 15393 dwelling units (6,1%)\nInvalid or out-of-scope cases - 20 888 dwelling units","data_appraisal":"Quality assurance was a feature of  questionnaire design in the survey, as well as the listing of structures, fieldwork (through extensive training and supervision and regular quality checks in the field). Automated and manual editing were carried out as part of the post-capture process during July\/August 2007 to ensure data consistency.\n\nCautionary note:\n\nThe Community Survey results were released on 24 October 2007. After the evaluation of the data by the Stats Council, the Community Survey was found to be comparable in many aspects with other Stats SA surveys, censuses and other external sources. However, there are some areas of concern where Statistics South Africa is urging users to be more cautious when using the Community Survey data. \n\nThe main concerns are:\n\n\u00b7The institutional population is merely an approximation to 2001 numbers and it is not new data.\n\u00b7The measure of unemployment in the Community Survey is higher and less reliable due to the differences in questions asked relative to the normal Labour Force Surveys.\n\u00b7The income includes unreasonably high income for children due to presumably misinterpretation of the question, e.g. listing parent's income for the child.\n\u00b7The distribution of households by province has very little congruence with the General Household Survey or Census 2001.\n\u00b7The interpretation of grants or those receiving grants need to be done with caution.\n\u00b7Since the Community Survey is based on random sample and not a Census, any interpretation should be understood to have some random fluctuation in data, particularly concerning the small population for some cells. The user should understand that the figures are within a certain interval of confidence.\n\nUsers should be aware of these statements as part of the cautionary notes:\n\n\u00b7The household estimates at municipal level differ slightly from the national and provincial estimates in terms of the household variables profile;\n\u00b7The Community Survey has considered as an add-on an approximation of population in areas not covered by the survey, such as institutions and recreational areas. This approximation of people could not provide the number of those households (i.e. institutions). Thus, there is no household record for those people approximated as living out of CS scope;\n\u00b7Any cross-tabulation giving small numbers at municipal level should be interpreted with caution such as taking small value in given table's cell as likely over or under estimation of the true population; \n\u00b7No reliance should be placed on numbers for variables broken down at municipal level (i.e. age, population group etc.). However, the aggregated total number per municipality provides more reliable estimates;\n\n\u00b7Usually a zero total figure (excluding those in institutions) reflects the fact that no sample was realised and in such cases this is likely to be a significant underestimate of the true population.\n\u00b7As an extension from the above statement, in a number of instances the number realised in the sample, though not zero, was very small (maybe as low as a single individual) and in some cases had to be re-weighted by a very large factor (maximum nearly 800 for housing weight and over 1000 for person weight).\n\u00b7As a further consequence, small sub-populations are likely to be heavily over- or under-represented at a household level in the data.\n\u00b7It should be noted that the estimates were done with the use of the de-facto population and not the de-jure population. The final presentation of results is presented on the de-jure population."}},"data_access":{"dataset_use":{"contact":[{"name":"DataFirst","affiliation":"","email":"","uri":"http:\/\/www.datafirst.uct.ac.za"}],"cit_req":"Publications based on datasets distributed by DataFirst should acknowledge relevant sources by means of bibliographic citations.
