Citizen data* refers to data originating from initiatives where people, communities or civil society organizations either initiate or are sufficiently engaged in the design and/or collection stages of the data value chain. It aims to inform decision-making, responding to the specific needs of a community, and can include community surveys, participatory mapping, social audits, crowd-sourced reporting, and more. When designed and managed responsibly, citizen data can supplement official data, filling critical gaps, particularly for marginalized groups who are often left out.

Citizen data empowers communities to produce information that complements official statistics, fills critical data gaps, and informs more inclusive decision-making. The resources in this section illustrate how citizen data can be collected, integrated into official data systems, and used to influence policy and practice. While citizen data may vary in scale and methodology, this section demonstrates that community-led evidence is a vital component of inclusive data systems, enhancing both the relevance and responsiveness of data-driven decisions. Moreover, it shows how effective partnerships between NSOs and communities can solve data challenges and ensure underrepresented voices are heard.

Integrating citizen data into inclusive data systems requires careful attention to data quality, comparability, ethics, and collaboration between civil society and NSOs. The resources in this section make the case for citizen data, set out the principles, provide guidance, and showcase how different actors have implemented citizen data projects. Users from NSOs to CSOs can learn approaches to ensure citizen data is both credible and actionable.

*Citizen data is an all-encompassing term defined in The Copenhagen Framework on Citizen Data. However, many data actors use terms such as citizen-generated data, community data, and more interchangeably. Here the term “citizen” refers to an individual in a society without any connotations related to citizenship.
