The GitHub Innovation Graph aggregates developer activity on GitHub into eight core metrics. These metrics are aggregated by economy, our innovation-focused term for geographies around the world based on ISO 3166. Each metric is reported quarterly dating back to January 2020 and is updated with a one quarter delay.
Only public activity is included. Metrics for economies are only reported when there are 100 or more unique developers performing the relevant activity within the time period. See the datasheet in our repository for more on the metrics, definitions, representativeness, and limitations of the GitHub Innovation Graph.
