Why it matters
A figure is only citable when a reader can check where it came from. This page fixes the dataset, the method and the data date next to the claim itself, so a journalist, researcher or answer engine can quote the number without asking anyone for the source.
Limitations
- Research findings describe the closed period stated on the page; a later period may differ.
- Findings are computed from Harpd Rank participation in the period, not from an independent market survey.
