How Americans use social media apps — the top behaviors

Here are the most common, search-driven ways people in the U.S. use social apps in 2025.

1. Content discovery & entertainment. Short-form video (15–60s) and algorithmic feeds are primary entertainment channels; people discover music, recipes, and viral trends here. Sensor Tower
2. News & civic information. Roughly half of adults say they at least sometimes get news via social media; Facebook, YouTube, TikTok and Instagram are major news sources for many. Pew Research Center+1
3. Social connection & messaging. Messaging and private groups (closed Facebook/Discord/Telegram channels) are popular for staying in touch with friends, hobby communities, and support groups.
4. Shopping & commerce. Social commerce (in-app shopping, livestream shopping) is mainstream: users browse and purchase directly from app storefronts and shoppable videos. Sensor Tower
5. Self-expression & creator economy. Millions of Americans create short videos, livestreams, and micro-blogs; creators increasingly monetize via tips, subscriptions, and branded content. Sensor Tower
6. Niche communities & learning. People use Reddit, Discord, LinkedIn, and specialized groups for learning, professional growth, and niche hobbies.

Who uses what — demographics and platform roles

Platform usage in 2025 retains strong age-based patterns, with notable nuances:

• YouTube: Near-universal reach across ages — top for long-form and short-form video and a dominant source of how-to content and entertainment. Sensor Tower
• TikTok: Still extremely popular among younger Americans for discovery, trends, and entertainment; growing as a news and commerce channel. Sensor Tower
• Instagram: Broad millennial and Gen Z appeal for visual storytelling, Reels, and commerce; half of U.S. adults report using it. Pew Research Center
• Facebook: Large reach among older adults and still influential for community groups, local news, and events. Pew Research Center
• Snapchat: Core for teens and young adults as a private-messaging-first platform with AR features.
• LinkedIn: Professionals and recruiters for career content, networking, and industry news.
• Reddit & Discord: Niche communities, discussion, and deep-dive info.

These distinctions matter for marketers: match content format (short video, long video, static image, text) to platform audience and purpose.

Time spent: how much are Americans on social media?

Average daily social-media time in the U.S. sits around 2–2.5 hours per day, depending on the study and cohort — with younger users skewing higher. Attention is fragmented across apps and short sessions; users hop from feed to feed rather than staying in one app for long stretches. Exploding Topics+1

What that means:

• Engagement is quick and frequent. Micro-moments matter (snackable content wins).
• Retention depends on novelty. Platforms that keep feeds interesting and personalized maintain higher daily active use.
• Ad models adapt. Brands invest in short ad formats and creator partnerships to capture micro-moments.

How social media affects wellbeing — what research says

Studies from U.S. universities and peer-reviewed journals (2024–2025) paint a nuanced picture: social media can both support wellbeing (social connection, peer support, learning) and pose risks (anxiety, sleep issues, social comparison), especially for younger people.

• Mental health links: Research at UNC–Chapel Hill and other centers continues to find associations between heavy social-media use, poorer sleep, and higher anxiety in adolescents and college students. The Surgeon General’s advisory (2023) remains influential in policy conversations. unc.edu+1
• Mechanisms: Social comparison, dopamine-reward loops, sleep displacement, and exposure to negative content are commonly cited mechanisms linking use to harm. Recent academic work highlights the role of frequency of upward social comparison as a risk factor. SpringerLink
• Positive effects: When used intentionally, social media supports community building, health information dissemination, and professional networking (e.g., peer support groups, telehealth outreach).

Practical takeaway: context and use patterns matter. Occasional, purposeful use is generally neutral-to-positive; heavy, passive scrolling is where most harms appear.

Trends that define 2025: what’s new and what’s growing

1. Short-form video dominance. Reels and Shorts compete with TikTok for attention and commerce. Sensor Tower
2. Social commerce accelerates. In-app shopping and livestream sales continue to grow as discovery and checkout fuse. Sensor Tower
3. AI-driven experiences. Recommendation engines and on-app AI (content summaries, creative tools) shape discovery and content creation. (See also rise of AI assistants and generative tools across apps.) Sensor Tower
4. Private & closed communities gain importance. Users favor invite-only groups and messaging for more meaningful interaction.
5. Platform diversification. People maintain presence on multiple apps to satisfy different needs (work, family, hobbies).
6. Increased scrutiny & regulation. Media literacy and policy debate continue as misinformation and youth safety remain concerns. Pew Research Center

Actionable advice — for creators, brands, parents, and everyday users

For creators & marketers

• Prioritize short-form, mobile-first content. Optimize for 15–60 second engagement and strong hooks in the first 1–3 seconds.
• Use platform-native commerce tools. Shoppable videos and live selling convert discovery into revenue faster. Sensor Tower
• Diversify distribution. Post native content across YouTube Shorts, Instagram Reels and TikTok — but tailor to each platform’s culture.
• Leverage micro-communities. Build an email list or Discord group to retain fans outside algorithm changes.

For parents & educators

• Talk about media literacy. Teach young people how feeds are engineered and how to check information sources.
• Set healthy boundaries. Encourage no-phone-before-bed routines and device-free family times. Research links heavy use to sleep disruption. unc.edu
• Model healthy use. Adults’ habits influence kids.

For everyday users

• Use features to manage time. Set app timers, focus modes, and curated lists.
• Be intentional. Follow accounts that teach, uplift, or connect you to your goals; mute or unfollow content that harms mood.
• Cross-check news. When you see breaking news, verify via trusted news organizations rather than sharing impulsively. Pew Research Center

Ethical and policy considerations in 2025

• Youth safety: Ongoing calls for stronger age verification, reduced addictive features, and clearer parental controls. Regulatory pressure continues. unc.edu
• Misinformation: Platforms and researchers (including Pew) keep tracking how people use social media for news; trust remains a central issue. Pew Research Center+1
• Privacy & data: As social commerce and AI tools grow, so do concerns about how personal data is used to target and monetize users.

Businesses and creators should be transparent about sponsored content, data use, and affiliations to maintain audience trust.
