For each of the eight African artists in the top 1,000 the twenty nearest-ranked non-African artists above and below were taken, excluding any already selected, giving a control of 160 artists drawn from the same stretches of the board. growth_31d_pct is the group\u2019s combined streams added between the 11 October and 11 November captures over its combined lifetime bank on 11 November. median_growth_31d_pct is the median of the same quantity computed per artist, which is reported because the combined figure is weighted by catalogue size and one large bank can dominate it. The control is a comparison of position on the board, not of release age, genre or market mix, none of which the leaderboard discloses. Stream columns are stated as whole streams. The leaderboard publishes the lifetime figure to one decimal place in millions, so every stream figure here is that published value multiplied by one million and is precise to the nearest hundred thousand streams, no further.","unit":"percent","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
