This report summarizes results from our representative Internet survey in 2019 and highlights major developments and trends of the past decade, based on data from our long-term biannual studies since 2011. The World Internet Project (WIP) is an international, collaborative science project which has been recording the dissemination and use of the Internet on an international basis since 1999. In 2019, the fifth World Internet Project - Switzerland (WIP-CH) survey was conducted. A rep-resentative sample of the Swiss population was interviewed about their Internet use and attitudes towards the Internet. Since 2011, over 5,500 interviews have been conducted within the WIP-CH, the results of which are presented in four thematic reports:1 Internet Diffusion and Digital Divides, Internet and Politics, Internet Applications and Usage, and Trust and Concerns of Internet Users in Switzerland.
