Nomination and winner data for this project is sourced from the Recording Academy, and data on gender and nationality has been supplemented from external artist biographies. Data reflects the first credited artist or group for each nomination.

For groups and bands, nationality data has been used where bios specify an origin and may not reflect the nationality of all band members - treat the demographic snapshots as directional context, not absolute truth.
