The Survey of Services 2013 was the first of its kind to be conducted in the Country. Prior to the Survey of Services 2013, ZIMSTAT conducted a Census of Distribution (COD) in 1980\/81, which focused on retail; wholesale; hotel and catering; and, the personal and household services trades only. The Survey of Services 2013 was therefore an expansion of the Census of Distribution covering sampled resident establishments whose main activity is classified as services according to the International Standard Industrial Classification of All Economic Activities (ISIC) Revision 4. The establishments covered were either registered and\/or licensed by an arm of government such as the Registrar of Companies, the Zimbabwe Revenue Authority (ZIMRA), Local Authorities and the National Social Security Authority (NSSA) among others.\n\nObjectives\nThe primary objective of the Survey was to produce up-to-date benchmark statistics on the size and characteristics of establishments whose main kind of economic activities are classified as services including, among others: \n\u2022 Turnover and expenditure \n\u2022 Number of persons engaged and their compensation\n\u2022 Gross Fixed Capital Formation  \n\u2022 Value Added\n\u2022 Taxation","time_periods":[{"start":"2013-01","end":"2013-12","cycle":""}],"coll_dates":[{"start":"2014-11-24","end":"2014-12-19","cycle":"Phase I"},{"start":"2015-01-26","end":"2015-02-24","cycle":"Phase 2"},{"start":"2015-04-13","end":"2015-05-04","cycle":"Phase 3"}],"nation":[{"name":"Zimbabwe","abbreviation":"ZWE"}],"geog_coverage":"National","analysis_unit":"Establishment","universe":"All service rendering establishments in the Central Business Register.","data_kind":"Sample survey data [ssd]","notes":"The 2013 Zimbabwe Survey of Services covered the following topics: \n- Establishment background\n- Owners, persons engaged and compensation of employees\n- Expenditure during 2013\n- Income during year 2013\n- Taxes paid in 2013\n- Subsidies and other incentives during 2013\n- Exports and imports during 2013\n- Inventories\n- Capital expenditure\n- Hours worked\n- Room unit and bed nights"},"method":{"data_collection":{"data_collectors":[{"name":"Zimbabwe National Statistics Agency","abbreviation":"ZIMSTAT","affiliation":"Ministry of Finance and Economic Development"}],"sampling_procedure":"Sampling Strategy\n(i) A Census was conducted on:\n\u2022 All establishments that are registered with the Registrar of Companies whose controlling enterprises are listed on the Zimbabwe Stock Exchange (ZSE) \n\u2022 Establishments with a Business Partner Number (BPN) issued by the Zimbabwe Revenue Authority (ZIMRA) upon registration for taxation purposes\n\u2022 Establishments dealing with specialized services that require a high degree of training, and make specialized knowledge and skills available to users such as legal, accounting and management consultancy activities\n\u2022 Establishments whose main kind of economic activity belonged to ISIC codes that were too few to be sampled\n\u2022 Establishments who did not respond to the Central Business Register Inquiry\n\n(ii) A Sample Survey was designed to cover:\n\u2022 Flea markets and hair salon operators\n\u2022 Establishments that did not meet the census criteria whose main kind of economic activity belonged to the following ISIC Rev. 4 codes:\nRetail sale in non-specialized stores with food, beverages or tobacco predominating\t\nRetail of food in specialized stores\t\t\t\t\t           \nRetail of beverages in specialized stores\t\t\t\t\t\nRetail sale of hardware, paints, and glass\t\t\t\t\t\nRetail sale of clothing, footwear and leather articles (excluding Flea-markets)\t\nPrimary education\t\t\t\t\t\nSecondary Education\t\t\t\t\t\nHair dressing and other beauty treatment\n\t\t\t\nA one-stage stratified sample design was used for the selection of establishments.

Four managers, one chief statistician and ten provincial supervisors were trained.

Data entry clerks went through a short training before the exercise. Each data entry clerk was given one batch at a time to enter or to verify. Respective batch numbers were allocated to respective data entry clerks so as to ensure accountability. The exercise was conducted mainly in pool offices for ease of monitoring the data entry process. Experienced coding and editing staff were assigned to the data entry pool offices to expeditiously attend to any queries arising during data entry. In addition, the SS project team members took turns to supervise the process and attend to problems."},"data_processing":"Data validation and cleaning process\nThe data entry template had inbuilt valid-value, valid-range and missing-value alerts on each electronically captured field (the inbuilt data entry checks have been appended). In the event that there were inconsistencies they would be immediately rectified. Double data entry was done on every questionnaire by two different data entry clerks to ensure correct variables were captured. Comparisons would be made between the first entry and second data entry files. Differences between the two files were rectified. The process would continue until there were no differences between the two files."}},"schematype":"survey","data_files":[],"variables":[],"variable_groups":[]}
