The survey was implemented by the National Bureau of Statistics (NBS), in collaboration with the Office of the Chief Government Statistician (OCGS) and other stakeholders, covering Mainland Tanzania and Zanzibar. The 2025 survey represents the first round (Round 1) of the CES programme. It is intended to establish a baseline for understanding enterprise activities and to support evidence-based economic planning, private-sector development and the production of official economic statistics. Future rounds may be conducted periodically, subject to national statistical priorities and available resources v0.1 Comprehensive Enterprise Survey (CES) Revenue and turnover Business characteristics Access to finance and credit Business constraints Green economy and environmental practice Gender and youth employment Business growth and performance International Standard Industrial Classification Management practices Competition and market condition Employment: full-time workers UNITED REPUBLIC OF TANZANIA The CES 2025 geographically covered Tanzania Mainland and Zanzibar. Nationally all the regions were covered by the survey. The Unit of observation was an establishment and data are coded by region and other administrative code/identifiers are available in the dataset. Sample survey data [ssd] National Bureau of Statistics Office of the Chief Government Statistician The CES 2025 sampling frame was developed from the 2023/2024 Statistical Business Register. The sampling frame contained information required for stratification, sample allocation, establishment identification and field operations. In particular, the principal variables used in the sample design were: geographical location, establishment size and economic activity. These variables were used to form the sampling strata and to ensure that the sample adequately represented establishments with different geographical, structural and economic characteristics. The resulting location-by-economic-activity-by-size strata constituted the basic domains for sample allocation and selection. Computer Assisted Personal Interview [capi] The CES questionnaire was designed to collect comprehensive information on the characteristics, operations and performance of business establishments. It was structured into modules covering establishment identification and general information, employment, purchases, operating costs, goods purchased for resale, sales and distribution, income, green economy, business disputes and management systems, competition, and other relevant aspects of business operations. Prior data collection, training of enumerators and supervisors was conducted to equip them with necessary skills and interview techniques. Enumerators were trained on the questionnaire, concepts, interview procedures, use of the electronic data-collection application and quality-control requirements before fieldwork. Data collection was carried out between March and May, 2026 for both Mainland Tanzania and Zanzibar. The CAPI system incorporated programmed checks, skip patterns and consistency controls to minimize errors during data collection. Enumerators were also required to review completed interviews before submitting to supervisors. Supervisors and quality-control personnel monitored fieldwork progress and reviewed submitted questionnaires to identify incomplete interviews, inconsistencies, unusual values and other potential data-quality problems. Data collection was supervised by regional coordinators and field supervisors from NBS and OCGS. Supervisors monitored enumerators, reviewed completed questionnaires, conducted quality control checks, and ensured compliance with survey procedures through regular field visits. Data editing involved both automated and manual validation procedures. Completed questionnaires were checked for completeness, consistency, logical errors, missing values, and outliers. Identified issues were corrected through data verification with field teams and respondents before the final dataset was prepared for analysis. The survey covered 9,889 establishments in Tanzania, comprising 8,624 establishments from Mainland Tanzania and 1,265 from Zanzibar. In Mainland Tanzania, the establishments included 512 large, 1,800 medium, and 6,312 small establishments. In Zanzibar, the sample comprised of 58 large, 198 medium and 1,009 small establishments. Overall, 9,497 establishments completed the survey, while 321 establishments refused to participate, resulting in a response rate of 96.7 percent. The high response rate was largely attributed to effective field coordination, monitoring, and active engagement with respondents throughout the data collection period. Sampling errors were calculated for selected key indicators, including standard errors, coefficients of variation, design effects, and design factors. The calculations considered the survey design and sampling weights, and results are presented in the CES report Data quality was assessed through completeness and consistency checks, outlier detection, and comparison with existing administrative and historical industrial data to ensure reliability This Survey is conducted in accordance with the Statistics Act Cap 351 R.E. 2023 Tanzania Mainland and Statistics Act, No. 9, 2007 of Zanzibar.
