Open data refers to data that is freely available to everyone to use and republish without restrictions. Sources of open data include data from science, governments, and open data communities. Open data from governments can improve transparency, empower citizens, and foster innovation and economic growth when accessed. Finally, open data is playing a role in solving public problems by giving citizens and policymakers access to data-driven assessments and enabling more targeted interventions.
