A reading missing from this table is not evidence the composition was different that day, only that this desk did not register a separate country breakdown for it. Core countries are Nigeria, Egypt, Morocco and South Africa, the only four African markets Spotify itself publishes a daily chart for, and the only four present on every one of the 17 readings. countries_n counts every distinct origin country with at least one of the panel's 50 artists that day. periphery_artists is the number of the 50 panel seats held by artists from outside the core four; periphery_countries lists those countries by name. core_share_pct and periphery_share_pct split that day's total panel daily streams (not seats) between the core four and everyone else; for the seven readings below with no periphery country, periphery_share_pct is 0 and core_share_pct is 100 by construction. For 28 Aug, 4 Sep, 26 Sep, 27 Sep and 2 Oct the split is carried over unchanged from panel-country-diversity-series-02-october-2026. For 3, 11 and 17 October, the source dataset reported country totals that already summed to the full 50-artist, 100-percent panel with no periphery row, so periphery_share_pct is 0 by construction, not assumed. For 5, 6, 8, 22, 23, 24 and 30 October, periphery_share_pct was computed as that date's periphery countries' summed daily_streams (or panel_streams, or value_0X_oct, per the source dataset's own column names) divided by the date's panel total daily streams, taken from the same source dataset; core_share_pct is 100 minus that figure. artists_core4_pct is (50 minus periphery_artists) divided by 50.","unit":"mixed","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
