{"id":5067,"slug":"african-export-footprint-august-vs-september-2026","title":"What moved in African artists’ Spotify chart footprint: August against September 2026","source":"Computed from this desk's african-presence-over-time panel series","source_url":"https:\/\/kworb.net\/spotify\/","source_type":"computed","method":"The twenty-three collection dates in african-presence-over-time are split into two windows at 1 September 2026: eleven collections from 13 to 31 August, and twelve collections from 1 to 19 September. For each metric the arithmetic mean across the collections in each window is taken, and change_pct is the September mean against the August mean. Means rather than endpoints are used because this panel is a daily chart and single dates swing: the August window's own export_streams range is 337,556 to 454,862. \"Markets of 75 carrying none\" is 75 minus the mean markets_charting for the window, so it is a mean of a count and is reported to two decimal places rather than rounded to a whole market. Collection dates are not evenly spaced and are not a calendar month, so these are means over the dates this desk collected, not over August and September.","unit":"","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
