Analysis
On TikTok, the share of users who comment and engage publicly rises with every age band, reaching 18.5% among the 55+ group — nearly twice the 9.7% rate among 18–24-year-olds. YouTube shows no such gradient; its Voicer share hovers between 5% and 8% regardless of age, while its Lurker share actually climbs from 5.8% among younger users to 11.3% among those 55 and older.
Older TikTok users arrive ready to participate — not just watch
TikTok's older audience has grown dramatically in recent years: adoption among users 45 and older surged from 2% in 2019 to 26% by 2025. This was not a passive migration — research suggests older users increasingly seek out value-driven, community-oriented content and are more likely to respond to it. The For You Page also removes the follower-count barrier that can discourage first-time commenters on creator-centric platforms, making it easier for any user to feel their voice reaches an audience. On YouTube, older users face a different dynamic: they skew toward intentional, search-driven viewing where the norm is to watch and move on, which explains the rising Lurker share with age. For marketers, this upends the assumption that older cohorts are purely passive audiences — on TikTok, the 55+ group is proportionally the most vocal segment of all. For the within-user view of these platform differences, see the dual-platform voice ratio comparison.

Methodology
The analysis covers 30,296 users active on either TikTok or YouTube during 2025 (at least 50 interactions on the respective platform). Each user was assigned to an engagement tier based on their voice ratio — the share of public actions in their total activity: Lurker (0%), Passive (above 0% to 2%), Active (2–20%), or Voicer (above 20%, with at least 200 interactions). Age was calculated from birth year and grouped into five bands (18–24, 25–34, 35–44, 45–54, 55+). Users without a recorded birth year and those under 18 were excluded. Each age-platform cell contains at least 110 users. The chart shows the tier composition within each age band separately for TikTok and YouTube.
