{"id":4068,"slug":"south-africa-chart-gain-origin-split-07sep2026","title":"Origin split of South Africa’s Spotify chart gain in African-origin streams, 13 August to 7 September 2026","source":"Computed from this desk's dataset south-africa-chart-african-stream-change-by-artist-aug-sep-2026","source_url":"","source_type":"computed","method":"Grouped the 27 artist rows in south-africa-chart-african-stream-change-by-artist-aug-sep-2026 by registered country of origin and summed gain_streams (the gross increase; declines are zeroed there, so this is not a net figure) and change_streams (the true net, including declines) for each country. share_of_gain_pct is each country's share of the 694,698-stream gross increase across all 27 artists. n_artists is a count of rows, not of unique individuals beyond what the source table lists. Two of the 25 South African-origin rows recorded a decline (Nontokozo Mkhize, Spirit Of Praise) and contribute 0 to gain_sum but a negative value to net_sum, which is why net_sum is below gain_sum for South Africa. The only non-South African origin present in the 27 rows is Nigeria (Ayra Starr, Tems); no other African country's artists appeared on South Africa's chart on both comparison dates in a way that registered a gain.","unit":"streams","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
