How We Charted the Decade: Billboard's decade-end recaps encompass chart performance from Dec. 5, 2009, through Sept. 28, 2019 (except for those for the Social 50, which began on Dec. 11, 2010, and Hot Dance/Electronic Songs and Streaming Songs, each of which launched on Jan. 26, 2013).
On decade-end Hot Songs and Top Albums recaps, titles are ranked based on an inverse point system, with weeks at No. 1 on weekly charts earning the greatest value and weeks at lower positions earning the least. Due to changes in chart methodology and title turnover rates over the decade, certain periods were weighted differently.
Top Artists recaps are ranked based on a formula blending performance, as outlined above, of all their chart entries. Specifically, the overall Top Artists category ranks the best-performing artists based on activity on the Billboard Hot 100 songs chart and the Billboard 200 albums tally, as well as social media data and touring revenue from Billboard Boxscore, while genre-focused Top Artists rankings blend acts' decade-spanning performance on each genre's main song and album charts (such as, for country, Hot Country Songs and Top Country Albums).
Billboard's decade-end touring charts are based on Billboard Boxscore data for performances between Dec. 1, 2009, and Sept. 30, 2019.
