{"id":5784,"slug":"export-share-break-comparison-2026","title":"African export share, average before and after the 20 September 2026 break","source":"Computed from this desk's african-presence-over-time series","source_url":"https:\/\/kworb.net\/spotify\/","source_type":"computed","method":"Every row of african-presence-over-time was split into two groups by date: the 23 collection dates from 13 August to 19 September 2026 (before the african_share break to a series high on 20 September), and the 6 collection dates from 20 to 26 September 2026 (on or after it). export_share was averaged, unweighted by day, within each group. pct_vs_other_period expresses each group's mean as a percentage difference against the other group's mean: for the earlier period it is how much higher its mean is than the later period's; for the later period it is how much lower its mean is than the earlier period's. This is a comparison of two short, unequally sized samples (23 dates against 6), not a trend line, and collection is not daily within either window.","unit":"percent","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
