The phenomenon of digital platforms, which has been a major global disruption in the world of work for nearly a decade, is relatively new in Argentina. By early 2016, five platforms operated in the country, all of them domestically owned. Starting that year, due to factors such as the flexibilization of the payment system for international transactions and others, the entry of new platforms and subsidiaries of foreign companies into the Argentine market accelerated. This influx also boosted new investments directed at locally established platforms. ETP18 is a database on the key characteristics of platform economy activities and workers’ perceptions of these platforms in Argentina in 2018. It provides unique insights aimed at generating new knowledge through this research. The survey was conducted with workers from 11 selected platforms: Mercado Libre, Airbnb, Uber, Cabify, Zolvers, Ando, Glovo, Rappi, Workana, Freelancer, and IguanaFix. The database comprises a sample of 603 cases. A triangulation of selection strategies was implemented due to the varying levels of difficulty in accessing workers across platforms. The sample was non-probabilistic, and the number of respondents per platform was determined using uniform quotas, considering the accessibility of workers for each platform.
