Source: Original table based on the Firm-level Adoption of Technology (FAT) survey. a. For Bangladesh, the sampling frame was based on the latest establishment census available complemented with an updated list from the business registry. b. For Brazil, the information came from Relação Anual de Informações Sociais (RAIS), a matched employer-employee database covering all formal firms. Data for Brazil are only for the state of Ceará. c. For India, the sampling frame included firms with 10 or more workers and combines the latest establishment census (2013) for services and the ASI (2017–18) for manufacturing. Data for India are only for the states of Tamil Nadu and Uttar Pradesh.
Standard Industrial Classification of All Economic Activities (ISIC), Rev. 4. More specifically, the sample includes firms from the following ISIC Rev. 4 sectors: agriculture (ISIC 01, from Group A); all manufacturing sectors (Group C); construction (Group F); wholesale and retail trade (Group G); transportation and storage (Group G); accommodation and food service activities (Group I); information and communication (Group J); financial services (ISIC 64) (from Group K, financial and insurance activities); travel agency (ISIC 79, from Group N); health services (ISIC 86, from Group Q); and repair services (ISIC 95, from Group S). The survey was stratified according to the universe of establishments by sector of activity, firm size, and geographic regions. The sample is representative across these dimensions. For sectors, for all countries, the sample was stratified at least for agriculture (ISIC 01); food processing (ISIC 10); wearing apparel (ISIC 14); retail and wholesale (ISIC 45, 46, and 47); other manufacturing (Group C, excluding food processing and apparel); and other services (including all other firms, excluding retail). This sector structure of the data was used for most of the analysis in this volume. Additional sector stratification that was country specific included: motor vehicles (ISIC 29); leather (ISIC 15); pharmaceuticals (ISIC 21); land transport (ISIC 49); financial services (ISIC 64); and health services (ISIC 86). For the firm size stratification, there are three strata: small firms (5–19 workers); medium firms (20–99 workers); and large firms 210
