Lineup Demographics refers to the analytical study of diversity and representation in music festival lineups, examining the gender, racial, and ethnic composition of booked artists. This subcategory has gained prominence as the music industry faces scrutiny over inequality, with studies showing that male artists comprise 70-80% of festival bookings¹, while white artists dominate with 76% representation². The field tracks progress in diversity initiatives and advocates for more inclusive booking practices across festivals and live events.
