Seven social media platforms now each claim over one billion monthly active users, but the social media statistics for each platform tell very different stories. This article breaks down user counts, advertising reach, demographic profiles, and engagement patterns for every major platform so you can see exactly who is on each one and how they use it.
Quick Facts by Platform
Facebook — 3.07 billion MAU | 71% of US adults | highest multiple-daily-use rate
YouTube — 2.58 billion ad reach | 84% of US adults | top app by behavioural data
Instagram — 3 billion MAU | 80% of US adults aged 18–29 use it
TikTok — 1.99 billion ad reach | fastest US growth since 2021 | ~50% daily use among under-30s
WhatsApp — 3 billion MAU | second in app behavioural index globally
Reddit — 765 million ad reach | steepest education skew of any major platform
X (formerly Twitter) — 557 million ad reach | 10% daily use among US adults
Snapchat — 932 million MAU | 58% usage among US adults aged 18–29
Pinterest — 578 million MAU | above-average brand research intent
LinkedIn — 1.33 billion registered members | does not publish MAU figures
Why Platform-Level Social Media Statistics Matter
Aggregate numbers "5.66 billion social media users globally" are useful for context, but they don't help you understand who is actually reachable on any given platform, or what those users are there to do. Platform-level data tells a more useful story.
Three measurement types appear throughout this article. Company-reported monthly active users (MAU) come directly from each platform. Self-reported survey data comes from Pew Research Center's 2025 survey of 5,022 US adults.
App behavioural index data comes from Similarweb, which tracks which apps people actually open on their smartphones rather than relying on self-reports. Where these produce different results and they often do both figures are shown.
In practice, content teams and media planners commonly find that the platform with the largest global MAU isn't necessarily the right fit for a specific audience. Demographic composition, daily engagement habits, and primary use cases all matter as much as raw size.
According to data from Statista, the most popular social networks worldwide ranked by monthly active users shows a landscape where the top platforms each serve meaningfully different audiences and geographies.
Facebook Statistics
How Many People Use Facebook?
Facebook holds the highest company-reported monthly active user figure of any social platform: 3.07 billion MAU. Its advertising reach figure is 2.35 billion somewhat lower, as ad reach reflects the addressable paid audience rather than total users.
Among US adults, 71% report using Facebook second only to YouTube. In Similarweb's app behavioural index, Facebook scores 77.1, placing it fourth behind YouTube, WhatsApp, and Instagram. That's a meaningful gap from the top three, and suggests that while Facebook has the largest registered user base, it doesn't necessarily command the most consistent daily app-opening behaviour globally.
As reported by TechCrunch, Facebook crossed the 3 billion monthly active user mark based on Meta's own quarterly earnings disclosures a milestone that underscores the platform's continued scale despite declining popularity among younger demographics.
Who Uses Facebook?
Age Group | % of US Adults Who Use Facebook |
Ages 18–29 | 68% |
Ages 30–49 | 80% |
Ages 50–64 | 74% |
Ages 65+ | 57% |
Facebook's age distribution is unlike most other platforms. Its heaviest US usage is among 30–49 year olds (80%) not the youngest adults. That 68% figure for 18–29 year olds is still high, but it's notably lower than the same group's usage of YouTube (95%), Instagram (80%), or TikTok (63%).
Women are more likely than men to use Facebook. Usage is relatively consistent across income and education groups compared to more demographically concentrated platforms like Reddit or TikTok.
How Often Do People Use Facebook?
About 50% of US adults use Facebook daily. 37% use it several times a day the highest multiple-daily-use rate of any platform in Pew's 2025 data. The 30–49 (58%) and 50–64 (54%) age groups lead daily use. Messaging friends and family is the primary draw, according to GWI research on platform use motivations.
YouTube Statistics
How Many People Use YouTube?
YouTube's advertising reach is 2.58 billion the highest of any platform. In Similarweb's app behavioural index it scores 100, placing it at the top. Among US adults, 84% report using it the most widely used platform in the country by a clear margin.
What's interesting is that YouTube sits in an unusual category. It's simultaneously a video platform, a search engine, and a social network depending on how you use it. That flexibility likely contributes to its unusually broad reach across age groups and demographics.
Who Uses YouTube?
Age Group | % of US Adults Who Use YouTube |
Ages 18–29 | 95% |
Ages 30–49 | 92% |
Ages 50–64 | 85% |
Ages 65+ | 64% |
YouTube is the only platform in Pew's 2025 survey where a clear majority of every age group including adults 65 and older reports using it. That 64% figure for the oldest cohort is significantly higher than any other platform in that age group. Usage is strong across all education levels, income brackets, and demographic categories.
How Often Do People Use YouTube?
About 50% of US adults use YouTube daily, with 33% doing so several times a day. Younger adults are the most likely daily users a majority of 18–29 year olds report visiting YouTube at least once a day.
In practice, organisations running video content commonly find YouTube's demographic breadth makes it one of the more predictable platforms for consistent reach across a mixed-age audience.
Instagram Statistics
How Many People Use Instagram?
Instagram reports 3 billion MAU equal to WhatsApp and just below Facebook. Its advertising reach is 1.91 billion. Among US adults, 50% report using it making it the only platform besides YouTube and Facebook used by at least half of all American adults.
In Similarweb's behavioural app index, Instagram scores 79.9, placing it third. That's a narrower gap from WhatsApp (86.5) than from YouTube (100), reflecting meaningful daily engagement.
Who Uses Instagram?
Demographic | % Who Use Instagram |
Ages 18–29 | 80% |
Ages 30–49 | 62% |
Ages 50–64 | 40% |
Ages 65+ | 19% |
Women | 55% |
Men | 44% |
Hispanic adults | 62% |
Asian adults | 58% |
Black adults | 54% |
White adults | 45% |
Instagram has one of the sharpest age gradients of any major platform. The 61-percentage-point gap between 18–29 year olds (80%) and 65+ adults (19%) is among the widest in Pew's data.
The racial and ethnic differences are also notable Hispanic and Asian adults use Instagram at meaningfully higher rates than White adults.Younger users in Western markets are more likely to name Instagram as their favourite platform not just one they use, but one they prefer. That affinity distinction matters for engagement quality beyond raw reach figures.
What Do Instagram Users Do on the Platform?
Publishing and sharing personal content is significantly more popular on Instagram than on TikTok, Reddit, or LinkedIn. Users show above-average interest in self-expression. This makes Instagram's content environment meaningfully different from platforms where consumption rather than creation dominates.
TikTok Statistics
How Many People Use TikTok?
TikTok's advertising reach is 1.99 billion adults aged 18 and above. Among US adults, 37% report using it up from 21% in 2021, the largest percentage-point growth of any platform over that period. In Similarweb's app behavioural index, TikTok scores 67.1, placing it fifth.
Who Uses TikTok?
Demographic | % Who Use TikTok |
Ages 18–29 | 63% |
Ages 30–49 | 44% |
Ages 50–64 | 30% |
Ages 65+ | 12% |
Women | Slightly higher than men |
College graduates | Lower than non-graduates |
Democrats | Higher than Republicans |
TikTok's education skew is worth flagging. Adults with lower levels of formal education are more likely to use TikTok than those with a college degree which is the reverse of platforms like Reddit, WhatsApp, and Instagram. This doesn't reflect content quality in either direction; it simply describes different audience compositions that matter for targeting.
How Often Do People Use TikTok?
24% of US adults use TikTok daily. Among 18–29 year olds specifically, roughly 50% use it daily compared to just 5% of adults 65 and older. That 45-percentage-point gap within the same country, on the same platform, is striking.
What's often overlooked is how TikTok's daily engagement rate compares to its overall penetration. At 37% overall usage but 24% daily use, TikTok's ratio of daily users to total users is higher than most platforms suggesting the people who use it tend to use it a lot.
What Do TikTok Users Do on the Platform?
Funny and entertaining content is the primary draw. Messaging and social connection are significantly less central than on Facebook or WhatsApp. Self-publishing is less common than on Instagram and Snapchat. TikTok is, first and foremost, a consumption platform users come to watch, not primarily to post or chat.
WhatsApp Statistics
How Many People Use WhatsApp?
WhatsApp reports 3 billion MAU matching Instagram. In Similarweb's behavioural app index it scores 86.5, placing it second globally behind YouTube and ahead of both Instagram and Facebook. Among US adults, 32% report using it.
That gap between its global app behavioural ranking (second) and its US self-reported usage (32%) tells a story. WhatsApp's strength is concentrated outside the United States particularly in Latin America, South Asia, and Europe, where it functions as the default messaging infrastructure for large populations.
Who Uses WhatsApp in the US?
Age Group | % of US Adults Who Use WhatsApp |
Ages 18–29 | 37% |
Ages 30–49 | 40% |
Ages 50–64 | 30% |
Ages 65+ | 20% |
College-educated adults are more likely to use WhatsApp than those with less formal education. Hispanic, Asian, and Black adults use it at higher rates than White adults. Democrats are more likely than Republicans to report using it. WhatsApp's US audience skews toward users with international connections or communities where it serves as the primary group communication tool.
WhatsApp vs. Other Meta Platforms
At first glance it seems odd that WhatsApp ranks higher than Facebook in daily app-opening behaviour globally, given Facebook's larger MAU figure. But the distinction makes sense when you consider use case.
WhatsApp is a messaging tool people open it to respond to messages, which creates high-frequency, short-session behaviour. Facebook involves more passive browsing. Different use cases produce different engagement patterns.
Understanding these platform dynamics is part of broader financial modeling and budgeting decisions that digital teams and growth-stage companies face when allocating media spend across channels.
Reddit Statistics
How Many People Use Reddit?
Reddit's advertising reach is 765 million. Among US adults, 26% report using it up from 18% in 2021, consistent growth over four years. Men are more likely than women to use Reddit.
Who Uses Reddit?
Demographic | % Who Use Reddit |
Ages 18–29 | 48% |
Ages 30–49 | 35% |
Ages 50–64 | 16% |
Ages 65+ | 6% |
College graduates | ~40% |
Some college | 28% |
High school or less | 15% |
Reddit shows the steepest education gradient in Pew's entire 2025 dataset. The gap between college graduates (~40%) and those with a high school education or less (15%) is larger here than on any other platform surveyed. Combined with its male skew and young-adult concentration, Reddit's audience composition is among the most specific of the major platforms.
In practice, this specificity can be an advantage. Teams working in tech, finance, gaming, or other interest-driven categories often find Reddit's community structure allows for more targeted reach than broader platforms though the platform's culture also means promotional content tends to be received poorly unless handled carefully.
For startups evaluating audience channels, pairing platform data with a solid fundraising strategy can help prioritise where early community-building efforts are best directed.

X (Formerly Twitter) Statistics
How Many People Use X?
X's advertising reach sits at 557 million the lowest of the platforms included in Kepios's top-16 ranking. Among US adults, 21% report using it. Daily use is 10% of US adults the lowest daily engagement rate of any major platform in Pew's 2025 data.
Who Uses X?
Age Group | % of US Adults Who Use X |
Ages 18–29 | 33% |
Ages 30–49 | 25% |
Ages 50–64 | 16% |
Ages 65+ | 10% |
Men are more likely than women to use X. The platform's political composition shifted noticeably between 2023 and 2025 in 2023, Democrats were more likely to use X than Republicans (26% vs. 20%). By 2025, that had reversed: Republicans now report higher usage (24% vs. 19% Democrats). That's a meaningful platform identity shift within two years.
X's 10% daily use rate is worth contextualising. Among the adults who do use X, engagement tends to be concentrated among a smaller, more active subset a pattern commonly observed with text-heavy, real-time platforms.
Snapchat Statistics
How Many People Use Snapchat?
Snapchat reports 932 million MAU. Among US adults, 25% report using it. Its age distribution is one of the most concentrated of any major platform.
Who Uses Snapchat?
Age Group | % of US Adults Who Use Snapchat |
Ages 18–29 | 58% |
Ages 30–49 | 31% |
Ages 50–64 | 13% |
Ages 65+ | 4% |
That drop from 58% among the youngest adults to 4% among the oldest is among the steepest age gradients in Pew's data comparable to TikTok. Like Instagram, Snapchat users show above-average interest in publishing and sharing personal content, distinguishing it from consumption-first platforms.
LinkedIn, Pinterest, and Emerging Platform Statistics
LinkedIn reports 1.33 billion registered members. This figure is important to understand correctly it represents total accounts ever created, not monthly active users. LinkedIn does not publish MAU data, which makes direct comparison with other platforms unreliable.
Kepios excludes LinkedIn from its MAU ranking for this reason. Treating LinkedIn's 1.33 billion figure as equivalent to Facebook's 3.07 billion MAU or YouTube's 2.58 billion ad reach would be comparing fundamentally different metrics. Primary use case is professional networking and career-related content.
Pinterest reports 578 million MAU. What distinguishes Pinterest in the platform data is user intent Pinterest users show above-average interest in researching brand-related content and products compared to users on most other major platforms.
This purchase-intent signal is relatively unique in the social media landscape. For businesses evaluating platforms with strong commercial intent signals, understanding how finance and crypto network audiences overlap with Pinterest's product-research-oriented user base can surface useful cross-channel insights.
Threads, Bluesky and Truth Social
Platform | % of US Adults Who Use It |
Threads | ~10% |
Bluesky | ~5% |
Truth Social | ~4% |
All three compete in the real-time text post space that X currently dominates at 21% US adult usage. The gap between X and its nearest competitor in this category (Threads at ~10%) is still substantial. Whether that gap closes in the next survey cycle will be one of the more watched data points in platform statistics.
Social Media Advertising Reach by Platform — Compared
Advertising reach figures come from each platform's own self-service advertising tools, compiled by Kepios. These figures represent the addressable audience for paid campaigns — they are generally lower than total MAU figures, and they are not all measured the same way.
Social Media Advertising Reach by Platform (2026)
Platform | Metric Type | Estimated Reach |
YouTube | Ad Reach | ~2.6 billion |
Ad Reach | ~2.3 billion | |
TikTok | Ad Reach | ~2.0 billion |
Ad Reach | ~1.9 billion | |
Registered Members (not MAU) | ~1.4 billion | |
Messenger | Ad Reach | ~1.0 billion |
Snapchat | MAU (company-reported) | ~1.0 billion |
Ad Reach | ~0.8 billion | |
MAU (company-reported) | ~0.6 billion | |
X (Twitter) | Ad Reach | ~0.5 billion |
The LinkedIn figure deserves particular attention. It is the only entry in this table based on registered members rather than active users or ad reach. Organisations planning LinkedIn campaigns should not assume 1.33 billion represents an active monthly audience it almost certainly does not.
What Ad Reach Figures Actually Mean
Ad reach and MAU are related but different. MAU counts everyone who used the platform in a given month. Ad reach counts only the subset targetable through paid advertising tools — which excludes users in certain countries, users below the advertising age threshold, and in some cases inactive accounts.
The gap varies by platform. For teams working through how to translate these reach figures into actual budget allocations, building a proper framework around financial modeling and budgeting practices helps avoid overestimating addressable audience size.
Which Platform Reaches Which Audience?
This table summarises the demographic and behavioural profile of each platform based on the data above. No recommendations purely what the data shows.
Conclusion
Each major platform serves a distinct audience with different habits, demographics, and intent. Facebook dominates daily use. YouTube spans all age groups. Instagram and TikTok skew young. Reddit skews educated and male. The data shows no single platform reaches everyone, audience fit matters as much as platform size.
Frequently Asked Questions
