While TikTok’s reputation as a Gen Z hangout persists in popular culture, the platform’s most dramatic growth story is unfolding in an unexpected demographic: older adults. New data reveals that TikTok usage among Americans aged 45 and older has exploded by 1,200% since 2019, fundamentally reshaping assumptions about who calls the short-form video platform home.
The Numbers Tell a Striking Story
Among users 45 and older, TikTok adoption has surged from just 2% in 2019 to 26% by 2025—a thirteen-fold increase that far outpaces growth in younger demographics. This represents one of the most significant shifts in social media adoption patterns in recent years.
Breaking it down by age group:
- Ages 35–44: adoption climbed from 7% to 44% (+529%).
- Ages 25–34: rose from 8% to 57% (+613%).
These mature millennials and younger Gen X users drive adoption rates, making TikTok’s expansion story far more complex than the simple “Gen Z app” narrative suggests.
Marketing’s New Reality: The Influencer Economy Matures
For brands and marketers, these TikTok demographic shifts represent a seismic opportunity. Social media’s purchasing influence extends far beyond Gen Z assumptions: 59% of US adults now follow influencers on social media, up from 44% in early 2024. Among those older than 45, that number is 38%, which has grown from 32% last year.
The real story lies in buying behavior:
- 32% of U.S. adults over 45 say social media influences their purchases at least a little.
- Electronics lead the way, with 29% influence among older adults.
- Steady gains are also seen in food and clothing.
Older demographics typically have more disposable income and make higher-value purchases—from home goods and travel to healthcare and financial services—making them especially valuable to brands.
The Broader Implications
This demographic transformation goes beyond marketing. The convergence of TikTok’s older user growth with rising influencer engagement across all age groups signals a fundamental shift in consumer behavior. When 59% of Americans follow influencers—nearly double last year’s rate—and older adults increasingly act on social media recommendations, traditional advertising models face disruption.
TikTok’s expansion into older age groups also reshapes political discourse, news consumption, and cultural conversations. Older adults are not just passive consumers—they create content, share perspectives shaped by decades of life experience, and make purchase decisions influenced by what they see on social platforms.

Looking Ahead
The 1,200% growth among users 45 and older is more than a statistical curiosity—it’s a fundamental shift in how we understand social media adoption and influence. The platform, once seen as a Gen Z enclave, has become a genuinely multi-generational space.
This evolution suggests that the future of social media may be less about age-specific platforms and more about creating compelling experiences that unite users across generational divides. TikTok’s success with older adults proves that when platforms prioritize engaging content and intuitive experiences, age becomes far less of a barrier than conventional wisdom suggests.
The mature digital wave isn’t just changing TikTok—it’s entirely rewriting the rules of digital engagement.
