Facebook use is relatively common across a range of age groups, with 68% of those ages 50 to 64 and nearly half of those 65 and older saying they use the site. https://pewrsr.ch/2P0uyRs pic.twitter.com/WyqYGuVUTc @facttank : There are substantial age-related differences among U.S. adults in use of social media platforms. This is especially true of Instagram and Snapchat, which are used by 67% and 62% of 18- to 29-year-olds, respectively. https://pewrsr.ch/2P0uyRs pic.twitter.com/tyHInESUiw @facttank : Amid some high profile controversies, Facebook users as a whole are just as active on the site today as they were a year ago. Roughly three-quarters of U.S. Facebook users (74%) visit the site daily https://pewrsr.ch/2P0uyRs pic.twitter.com/mcK6GYSe61 Syed / @gypsy_heart6 : Interesting! Reddit is a highly male space with few black people, Instagram & Pinterest female, white people don't use WhatsApp, old people only use Facebook, few poor folks on LinkedIn, Twitter is highly urban with more males. http://twitter.com/...

Context & Ripple Effects
Pew's early-2018 survey found nearly 75% of US adults on YouTube and heavy 18-24 usage of Snapchat, Instagram, and Twitter (the spring 2018 baseline). A year later — after a long run of platform controversies — the topline is statistically unchanged: YouTube 73%, Facebook 69%, Twitter 22%. The scandal cycle did not move the adoption needle.
What the aggregate hides is composition: Instagram sits at 67% and Snapchat at 62% among 18-29 year olds versus 37% and 24% overall, so the flat total masks churn between platforms and generations. Later Pew waves show where that churn went — Instagram climbing from 37% to 47% by the 2024 survey and TikTok reaching 37% by late 2025, while X/Reddit hold near the old Twitter level.
First-order effects
- Facebook and YouTube enter advertiser conversations with proof of durable reach — Facebook at 69% overall with 74% of its users visiting daily — rather than defensive narratives about users fleeing after controversies.
- Twitter's 22% adult penetration confirms it competes as a niche, high-influence platform, not a mass-reach buy.
Second-order effects
- With the US adult market effectively saturated, platforms' growth contests shift from acquiring non-users to poaching each other's demographics — which is why age-skewed services like Instagram and Snapchat carry the momentum the topline number lacks.
- Advertisers gain leverage: when total reach stops growing, pricing pressure moves toward whoever can demonstrate engagement depth (daily-visit rates) rather than raw audience size.
Third-order effects
- If the pattern holds, US social media behaves like a mature utility: adoption plateaus while share migrates across platforms and cohorts — the mechanism behind TikTok's rise and Instagram's teen-recruitment push visible in the later survey waves.
- A flat adoption curve makes regulatory and reputational shocks less commercially decisive than they appear, since users absorb controversies without leaving — raising the bar for what actually dislodges entrenched platforms.
The trend: US social media has been near saturation since 2018, so industry competition now plays out as share-shifting between platforms and generations rather than growth in overall adoption.
