Method
- Start from the Pinlyx Data API catalogues of public TikTok accounts and YouTube channels: 22,419 TikTok accounts, of which 21,657 (96.6%) carry the three counters the ratio needs, and 35,149 YouTube channels, read on 19 September 2026.
- TikTok, quoting the API’s definition: “Lifetime like total divided by lifetime video count, reported both absolutely and as a percent of followers. TikTok publishes no per-post data and no view counts to a logged-out reader, so this is the only engagement signal available at account level.” Accounts with no videos are excluded. Every band clears the API’s 100-account floor for a reliable band; the smallest holds 426.
- YouTube: views per day is the last observed lifetime view total minus the first, divided by the days spanned, over a 14-day window with at least five observed days. Percentiles are taken across every channel in the band. Three bands start at one million subscribers, and in each the measured count equals the channel count.
- One-day gains: the movers feed for 19 September 2026, the 100 largest audience gains per platform, counted into audience bands.
- All figures were read on 19 September 2026: the newest TikTok measurement at 10:34 UTC, the YouTube ladder computed at 10:48 UTC. The page rounds; the CSV keeps the original values.
Limits
The catalogues are built from lookups and monitoring, not drawn at random from either platform, so they do not represent the platform as a whole. Both lean toward large, English-language accounts: in the API’s own block samples, 99 of 156 TikTok rows and 106 of 165 YouTube rows were classified as English, and 48 of 140 YouTube channels as based in the United States; those samples are small and the API labels them approximate. TikTok publishes no view counts and no per-post data to a logged-out reader, so likes per video is the only engagement signal available, and it is a lifetime ratio: an account that was large three years ago and is quiet now still reports well. TikTok rounded follower and like counters above one million until 24 August 2026; the bands read each account’s current row, refreshed from exact counters since the cutover, so the rounding does not reach these figures. YouTube rounds subscriber counts to three significant figures at the source, which is why views rather than subscribers are benchmarked, why no views-per-subscriber figure is published, and why there is no band below one million subscribers. The one-day table is a single day ranked by absolute change and says nothing about smaller accounts.
