The Good Practice Principles for Data Ethics in the Public Sector support the ethical use of data in digital government projects, products, and services to ensure they are worthy of citizens' trust. The document introduces 10 Good Practice Principles for Data Ethics in the Public Sector, including a set of specific actions which can support their implementation. These Good Practice Principles were produced by the OECD Working Party of Senior Digital Government Officials (E-leaders) and are the result of the activities of its Thematic Group on Data-driven Public Sector. Between 2019 and 2020, the Thematic Group on Data-driven Public Sector was co-led by the OECD Digital Government and Data Unit and the Netherland’s Ministry of the Interior and Kingdom Relations with the participation from OECD member and partner countries.
