As of early 2025, social media has become a near-universal digital habit — with 5.24 billion users globally, representing 63.9% of the world’s population. Usage patterns, however, vary dramatically across age groups: from teenagers spending nearly 5 hours daily scrolling short-form videos to older adults spending around 1.7 hours primarily on Facebook. Age remains the single most powerful predictor of which platforms people use, how long they spend, and what motivates their engagement.
Social Media Adoption Rate by Age Group
The share of adults using social media declines steadily with age, though adoption remains surprisingly strong even among seniors.
| Age Group | Share Using Social Media (US) |
| 18–29 years | 84% |
| 30–49 years | 81% |
| 50–64 years | 73% |
| 65+ years | 45% |
| Teens (13–17 years) | 93%+ |
Teens represent one of the most heavily engaged cohorts — over 93% of U.S. teens use at least one social media platform, with nearly all of them (95%) on YouTube. The 65+ group, while showing the lowest adoption, has been growing steadily, with Baby Boomers increasingly active on Facebook and YouTube.
Generational Share of Total Users
Millennials dominate the total social media user base globally, followed by Gen X — with Gen Z’s share growing rapidly as that cohort ages into the platforms.
| Generation | Age Range | Share of All Social Media Users |
| Gen Z | 12–27 years | ~25% |
| Millennials | 28–43 years | ~37% |
| Gen X | 44–59 years | ~28% |
| Baby Boomers | 60+ years | ~10% |
Millennials form the largest slice at 37% of users, dominating Facebook (32% of its user base) and maintaining strong Instagram activity. Gen Z, despite representing a smaller overall share, punches above its weight in engagement intensity — they are the core audience driving TikTok and Instagram growth.
Daily Time Spent on Social Media by Age
Time spent is where the generation gap becomes starkest. Younger users spend dramatically more time on social platforms than older cohorts.
| Age Group | Avg. Daily Time on Social Media |
| Teens (13–17 years) | ~4 hours 48 minutes |
| Gen Z (16–24 years) | 3 hours 18 minutes – 4 hours |
| Millennials (25–34 years) | ~2 hours 20 minutes – 3 hours |
| Adults 35–44 years | ~2 hours 7 minutes |
| Adults 45–54 years | ~2 hours 10 minutes |
| Adults 55–64 years | ~2 hours 8 minutes |
| Adults 65+ years | ~1 hour 42 minutes |
Among teens, girls outpace boys — averaging 5.3 hours per day vs. 4.4 hours for boys. The most active adults are 16–24-year-olds, engaging on platforms 4.6 days per week for roughly 3.5 hours per day. The 25–34 group follows closely at ~4.4 days per week and just under 3 hours daily.
Time Spent by Platform and Age Group (Minutes/Day, US)
Breaking down time by specific platform reveals distinct generational preferences:
| Platform | 18–24 yrs | 25–34 yrs | 35–44 yrs | 45–54 yrs | 55–64 yrs | 65+ yrs |
| TikTok | 76 min | 50 min | 47 min | 45 min | 37 min | 29 min |
| 53 min | 37 min | 28 min | 27 min | 26 min | 20 min | |
| 22 min | 26 min | 30 min | 36 min | 45 min | 34 min | |
| Snapchat | 35 min | 27 min | 22 min | 22 min | 20 min | 19 min |
| Total | 186 min | 140 min | 127 min | 130 min | 128 min | 102 min |
A clear inverse relationship is visible: TikTok time drops sharply with age (76 → 29 min), while Facebook time peaks in the 55–64 range (45 min/day). The 18–24 group spends nearly twice as much total social media time as adults over 65 (186 vs. 102 minutes).

Facebook, meanwhile, shows remarkable consistency across Millennials, Gen X, and Boomers (all 77–89%), while dropping off sharply among Gen Z.
Platform Usage Among US Teens (Ages 13–17)
Teens represent a bellwether for future platform trends. Their current preferences diverge significantly from the overall adult population.
| Platform | Teen Usage Rate (US) |
| YouTube | 93–95% |
| TikTok | 63% |
| Snapchat | 55–60% |
| 59% | |
| 33% | |
| X (Twitter) | 20% |
Video-first platforms dominate teen attention, with video platforms now commanding over 85% of daily teen screen time. Nearly 1 in 5 teens (20%) reports being on TikTok or YouTube “almost constantly”, reflecting the power of algorithmic recommendation engines designed to maximize engagement.
Why Different Ages Use Social Media
Motivations for social media use also shift with age, according to GWI’s global survey data.
- All age groups: “Keeping in touch with friends and family” is the #1 motivation across all demographics
- 16–24 year olds: Only 48.3% cite this as a primary motivation — they are more driven by entertainment, discovery, and identity expression
- 65+ users: 58.1% cite keeping in touch as their primary reason — social connection is the dominant driver for older users
This age-based divergence explains why younger cohorts gravitate toward entertainment-first platforms (TikTok, YouTube, Instagram), while older adults favor community-oriented platforms like Facebook and messaging apps like WhatsApp.
Number of Platforms Used by Age
Younger users don’t just spend more time — they spread that attention across more platforms.
- Global average (16+ users): 6.83 platforms per month
- Users aged 16–24: 7.71 platforms per month — the highest of any age group
- Older users (45+): Tend to concentrate on fewer, established platforms (Facebook, YouTube, WhatsApp)
This multi-platform behavior among Gen Z creates both opportunity and complexity for brands and content creators targeting youth audiences.
Key Takeaways
- YouTube is the only platform with 65%+ penetration across all age groups — it’s the single most cross-generational social platform in 2025
- Facebook dominates 40+ demographics and sees daily use concentrated among 30–64 year olds
- TikTok and Instagram are Gen Z and younger Millennial territory, with usage declining sharply among Gen X and Boomers
- Time spent inversely correlates with age: teens at ~4.8 hours vs. seniors at ~1.7 hours daily
- Motivation shifts with age: entertainment and identity for youth; connection and news for older users
- Baby Boomers are a growing, underserved audience — while only 10% of total users, their adoption is rising and they show high platform loyalty, especially on Facebook.
