{"id":4209,"slug":"south-africa-chart-gain-origin-split-mondays-2026","title":"Origin split of South Africa’s Spotify chart gain in African-origin streams, Monday 17 August to Monday 7 September 2026","source":"Computed from this desk's dataset south-africa-chart-african-stream-change-by-artist-mondays-2026","source_url":"","source_type":"computed","method":"Grouped the 25 artist rows in this desk's dataset south-africa-chart-african-stream-change-by-artist-mondays-2026 by registered country of origin and summed, for each country, gain_streams (the gross increase, with declines zeroed, so this is not a net figure) and change_streams (the true net, declines included). Both endpoints of that source dataset are Mondays, 17 August and 7 September 2026, chosen so the comparison holds day of week fixed; this desk's collection series begins on Thursday 13 August 2026, which is the lowest-volume of the 16 collected dates for South Africa, and an uncontrolled pairing from that date produces a low-base artefact rather than a measurement. share_of_gain_pct is each country's share of the 296,602-stream gross increase across all 25 rows. net_share_pct is each country's share of the 275,772-stream net change. n_artists counts rows in the source table, not unique individuals beyond what that table lists; n_gaining and n_declining split those rows by direction and sum to n_artists. n_new_entrants counts rows whose streams_17_aug is exactly 0, meaning the artist held no place on South Africa's daily Spotify chart on 17 August; that is an absence from the chart, not an absence of listening. new_entrant_gain_sum sums gain_streams for those rows only and new_entrant_share_of_gain_pct expresses it as a share of the same 296,602-stream gross increase, so the two countries' figures are comparable and additive. Six of the 23 South African rows recorded a decline 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 25 rows is Nigeria, two artists; no artist from any other African country held a place on South Africa's daily chart on either Monday. Two dates is a comparison of two snapshots, not a trend, and chart streams are a sample of consumption inside a market's daily chart rather than a full accounting of streaming in that market. No cause is claimed for any individual movement.","unit":"streams","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
