GDELT: The Global Database of Events, Language, and Tone

From the about page:

The Global Database of Events, Language, and Tone (GDELT) is an initiative to construct a catalog of human societal-scale behavior and beliefs across all countries of the world over the last two centuries down to the city level globally, to make all of this data freely available for open research, and to provide daily updates to create the first “realtime social sciences earth observatory.” Nearly a quarter-billion georeferenced events capture global behavior in more than 300 categories covering 1979 to present with daily updates.

GDELT is designed to help support new theories and descriptive understandings of the behaviors and driving forces of global-scale social systems from the micro-level of the individual through the macro-level of the entire planet by offering realtime synthesis of global societal-scale behavior into a rich quantitative database allowing realtime monitoring and analytical exploration of those trends.

GDELT’s evolving ability to capture ethnic, religious, and other social and cultural group relationships will offer profoundly new insights into the interplay of those groups over time, offering a rich new platform for understanding patterns of social evolution, while the data’s realtime nature will expand current understanding of social systems beyond static snapshots towards theories that incorporate the nonlinear behavior and feedback effects that define human interaction and greatly enrich fragility indexes, early warning systems, and forecasting efforts.

GDELT’s goal is to help uncover previously-obscured spatial, temporal, and perceptual evolutionary trends through new forms of analysis of the vast textual repositories that capture global societal activity, from news and social media archives to knowledge repositories.

Key Features


  • Covers all countries globally
  • Covers a quarter-century: 1979 to present
  • Daily updates every day, 365 days a year
  • Based on cross-section of all major international, national, regional, local, and hyper-local news sources, both print and broadcast, from nearly every corner of the globe, in both English and vernacular

  1. […] I previously wrote about GDELT it wasn’t available for querying with Google’s BigQuery. That should certainly improve […]
