Social media now reaches 5.79 billion people, roughly two-thirds of everyone on the planet. The opportunity is obvious. The harder part is knowing which of these numbers actually hold up when you build a plan around them.

After fifteen years advising clients as a Fractional CMO and teaching social media at Rutgers Business School, I have learned that a marketing decision is only as good as the data underneath it. Bad data wastes budget. Worse, it sends you confidently in the wrong direction. So every figure below is current and pulled from the original source, not a roundup.

These 35 social media marketing statistics answer the questions I actually get asked. How many people are on social? Which platforms matter? Where is the ad money going? What does engagement really look like now? And the big one for 2026: what happens to social media as people start asking AI instead of searching?

How Many People Use Social Media in 2026?

As of April 2026, 5.79 billion people use social media, which works out to about two in three people on the planet. That number grew by 294 million in a single year. The average user now spends roughly 18 hours and 36 minutes a week on social platforms and online video, spread across 6.5 different networks each month.

1. 5.79 billion people use social media as of April 2026

That is about two in three people on Earth, and the total climbed by 294 million over the past year, according to DataReportal.

2. The average user spends about 18 hours 36 minutes a week on social and video

DataReportal’s data shows most of that time going to feeds, messaging, and online video, the equivalent of a part-time job every week.

3. The average person uses 6.5 social platforms a month

DataReportal tracks that activity spread across networks, which is why multi-channel coordination beats single-platform obsession.

Most brands read that 6.5 figure backwards. They treat it as pressure to be everywhere, when it is actually permission to be selective, because the audiences overlap heavily. If you understand where your specific customers spend their time, focusing on two or three platforms will outperform a thin presence on eight. That focus is the foundation of what social media marketing really involves.

Which Social Media Platforms Have the Most Users?

There is no single biggest platform, because it depends on what you measure. By advertising reach, the metric marketers care about most, YouTube leads, with ads reaching 2.65 billion people each month. Facebook follows at 2.39 billion, then TikTok at 2.21 billion and Instagram at 1.99 billion. LinkedIn rounds out the top five at 1.43 billion registered members.

4. YouTube’s ads reach 2.65 billion

That is the largest social advertising audience in the world, based on DataReportal’s ad-reach data.

5. Facebook’s ads reach 2.39 billion

DataReportal ranks it second only to YouTube, the giant nobody should write off.

6. TikTok’s ads reach 2.21 billion

That puts it third for global ad reach in DataReportal’s data, no longer the upstart.

7. Instagram’s ads reach 1.99 billion

That figure comes from DataReportal, and the app crossed 3 billion monthly active users in September 2025, according to CNBC, a milestone only Facebook had reached before.

8. Snapchat has 943 million monthly active users

Snapchat has 943 million monthly active users It also counted 477 million daily active users in its Q3 2025 results, a reminder that smaller platforms still command large, hard-to-reach Gen Z audiences.

If someone tells you Facebook is dead, run for the hills. The data says the opposite. What has changed is not Facebook’s size but its role in a wider mix, which is exactly why keeping an eye on social media trends beats reacting to whichever platform is having a news cycle.

Who Uses Social Media in the United States?

In the United States, YouTube and Facebook remain the most widely used platforms by a wide margin. 84% of U.S. adults use YouTube and 71% use Facebook. Instagram is the only other platform a majority touches, at 50%. TikTok sits at 37% and WhatsApp at 32%. Age changes the picture dramatically, which is the detail too many brands skip.

9. 84% of U.S. adults use YouTube

It is the most widely used platform in the country, ahead of every dedicated social network, per the Pew Research Center.

10. 71% of U.S. adults use Facebook

Pew ranks it second only to YouTube, reaching more Americans than any other social platform.

11. 50% of U.S. adults use Instagram

It is the only platform besides YouTube and Facebook that a majority of Americans touch, Pew reports.

12. 37% use TikTok and 32% use WhatsApp

Both trail the leaders in Pew’s data but skew heavily by age and community, which raises their value for the right audience.

13. 80% of adults aged 18 to 29 use Instagram, versus 19% of those 65 and older

Pew records one of the widest generational gaps in social media, a 61-point spread on a single platform.

That 61-point gap is the whole ballgame for targeting. A brand selling to retirees and a brand selling to college students are operating on different platforms even when they both say they do social media. Before you assume your audience is somewhere, confirm it with a proper social media audit of where they actually are.

How Are Marketers Using Social Media in 2026?

Marketers have largely settled on their core platforms, but momentum is shifting. Instagram is now the most-used platform among marketers at 70%, with Facebook close behind at 69.6%. TikTok adoption sits at 57% and is the fastest-growing platform in marketer adoption. When marketers rank what actually delivers, short-form video tops the list.

14. 70% of marketers use Instagram

That makes it the most popular platform in the marketer toolkit, according to HubSpot’s State of Marketing report.

15. 69.6% of marketers use Facebook

HubSpot puts it in a near tie with Instagram for everyday use.

16. 57% of marketers use TikTok, the fastest-growing platform in adoption

It is the fastest riser among marketers in HubSpot’s data, even though total adoption still trails Instagram and Facebook.

17. Short-form video is the highest-ROI format, with 48.6% of marketers ranking it top three

HubSpot’s State of Marketing report ranks it the top-performing format of 2026, ahead of every other media type.

Most brands stumble right here. They chase the platform that is trending instead of the format and channel that convert for their specific business. The fix is unglamorous: track your own results. Watching the right social media analytics tools will tell you more than any industry average ever can. On an episode of my podcast Your Digital Marketing Coach, I argued that the more we know, the more informed our decisions can be and the bigger impact we can have with the same budget. Statistics like these are the starting point. Your own first-party data is the finish line.

How Much Are Businesses Spending on Social Media Advertising?

Social media advertising spend is projected to reach 317.33 billion dollars worldwide in 2026, roughly three of every ten dollars spent on digital advertising. The United States is the single largest market at about 126 billion dollars. And the money keeps shifting to mobile, which is projected to carry more than 82% of social ad spend by the end of the decade.

18. Global social media ad spend is projected at $317.33 billion in 2026

That is around a third of all digital ad spend, according to Statista.

19. The U.S. is the largest social-ad market at $126 billion in 2026

Statista’s Social Media Advertising outlook puts the country well ahead of any other single market.

20. 82.9% of social ad spend will be mobile by 2030

Statista’s outlook shows budgets following people to the phone, where most scrolling already happens.

The number is staggering, but the lesson is not to spend more. It is to spend with data. A bigger budget poured into the wrong platform just loses money faster. Early on, paid social is most useful as a data-acquisition tool rather than a pure sales channel. It tells you which audiences, creative, and channels deserve more before you commit serious money. That principle applies whether you are a global brand or doing social media marketing for a small business on a shoestring.

What Do the Numbers Say About Video?

Video is the default format now. 91% of businesses use video as a marketing tool in 2026, and 93% of video marketers call it an important part of their strategy. On the demand side, 84% of consumers say they want to see more video from the brands they follow. Short-form in particular dominates both attention and reported ROI.

21. 91% of businesses use video as a marketing tool

Wyzowl’s research has the figure back at an all-time high after a brief dip.

22. 84% of consumers want more video from brands

Wyzowl finds the preference has held steady for years, with little sign of video fatigue.

23. 93% of video marketers consider video important to their strategy

Wyzowl’s State of Video Marketing survey records near-universal agreement on its value to the business.

The catch is volume. Wanting to make more video and actually staying on cadence are different problems, and the second one is where most teams break down. Picking your best times to post on social media helps, and so does choosing the right short-form video approach, but the real fix is a repeatable system rather than heroic bursts followed by silence.

What Are the Benchmarks for Social Media Engagement?

Engagement is shrinking, and that is the single most important context for everything else. The median Instagram engagement rate across industries sits at 0.36%. Every major platform saw engagement fall in 2025. Posting frequency is steady but modest, around four times a week on Instagram. Lower engagement makes consistency and format choice matter more than raw output.

24. Median Instagram engagement is 0.36% across industries

Rival IQ’s 2025 benchmark report treats it as the reference point for judging whether a brand account is actually performing.

25. Engagement fell on every major platform in 2025

Rival IQ’s 2025 report clocked the steepest drop on X, down 48%, followed by Facebook at 36%, TikTok at 34%, and Instagram at 16%.

26. Brands post about four times a week on Instagram

Top performers keep a similar cadence rather than flooding the feed, Rival IQ’s 2025 data shows.

These numbers sound discouraging until you reframe them. Falling engagement rates do not mean social stopped working. They mean the denominator grew and feeds got more crowded. Every like, comment, and share is worth more now, which is why I push clients to measure engagement rate against their own history rather than a generic benchmark. If you want a steadier number, study your highest-performing social media engagement posts and do more of what already works for your audience.

Is Social Media Replacing Search Engines?

This shift will define 2026, and it cuts two ways. 52% of users now prefer searching social platforms over AI chatbots when they want real opinions. At the same time, 92% of marketers are optimizing for AI-powered search, and nearly 30% report losing search traffic to AI tools. People are routing around traditional search and splitting between two destinations.

27. 52% of users prefer social search over AI chatbots

Sprout Social found that edge holds when people want authentic, human perspectives instead of a synthesized answer.

28. 92% of marketers are optimizing for AI-powered search

HubSpot’s State of Marketing report shows they are doing it alongside traditional search, not instead of it.

29. Nearly 30% of marketers report losing search traffic to AI

Most of those teams blame consumers shifting to AI tools for quick answers, per HubSpot.

Why does this matter for your strategy? Because social content is now doing double duty. It satisfies the people who search inside TikTok and Instagram, and well-structured social and blog content increasingly feeds the AI assistants that people ask instead of Google. The brands that win are not picking one. Listening to those conversations through social listening is how you find out what your audience is actually asking before you try to answer it.

How Does Social Media Influence Buying Decisions?

Social media now sits in the middle of the purchase journey, not at the edge. It is the leading source of brand discovery for younger audiences, and where customers expect to reach you. The headline stat: 73% of consumers say they will buy from a competitor if a brand ignores them on social. Responsiveness is a revenue lever.

30. 73% of consumers will switch to a competitor if a brand ignores them

Sprout Social found that one unanswered message is often enough to send a customer elsewhere.

31. Social ads are the top brand-discovery source for ages 16 to 34

DataReportal’s Digital 2026 report ranks them third overall, behind only search engines and TV.

The old post-and-pray playbook misses this entirely. The brands earning recommendations and repeat business are the ones actually in the conversation, answering questions, and treating their feed like a relationship. If you are not sure whether yours is doing that, a quick look at what you publish through the lens of social media management usually reveals the gaps fast.

How Are Brands Investing in Influencer Marketing in 2026?

Influencer marketing is being run as a core growth channel, not an experiment. 87.49% of brands expect to raise their influencer budgets in 2026, most manage programs in-house, and spending is shifting toward the smallest creators. Fraud is the risk that scales right alongside those budgets, which is why vetting matters more as you grow.

32. 87.49% of brands expect to increase their influencer budgets in 2026

Influencer Marketing Hub’s 2026 Benchmark Report found 72.22% of them planning increases of 50% or more.

33. 66.33% of brands run influencer marketing entirely in-house

Most teams now treat it as an owned channel rather than an outsourced service, per Influencer Marketing Hub.

34. 51.43% of brands plan to expand their use of nano-influencers

Influencer Marketing Hub records the highest growth intent at the smallest creator tier, not the largest.

35. Fake or bot followers make up 56.5% of reported influencer fraud

It is the single biggest quality risk in the channel, ahead of fake engagement or undisclosed ads, according to Influencer Marketing Hub.

The mistake I see most often is chasing the biggest follower counts. The returns usually come from fit, not fame. A creator whose audience genuinely overlaps with your customer will outperform a celebrity every time, which is the whole argument behind influencer marketing done well. It is also why the smart money keeps moving toward micro-influencers and nano creators, who deliver stronger engagement and trust per dollar than the household names. And with fake followers driving most reported fraud, audience verification is now table stakes before you sign anyone.

Putting These Social Media Marketing Statistics in Context

A few honest caveats, because data deserves them. Platform reach and user figures are not all measured the same way, so comparing them directly is rough. LinkedIn’s 1.43 billion, for example, counts registered members rather than active monthly users. Engagement benchmarks vary by source too, since each provider defines and calculates engagement differently, so treat the 0.36% figure as directional rather than absolute. Influencer market-size estimates also range widely depending on what is being counted.

Two more things worth keeping in mind. Self-reported usage and logged app usage often disagree, which is why the same platform can rank differently from one data source to the next. And the fastest-growing behavior now is depth rather than headcount. People spend more time and use more platforms even where new-user growth has flattened, so competition for attention keeps rising. AI-driven discovery is still early and volatile, so expect the social-versus-search numbers to keep moving through the rest of 2026.

The point of these 35 numbers is not to memorize them. It is to make better decisions than the marketer who is guessing. Build your plan on data, then keep measuring it, and you will be ahead of most of your competition by default. No benchmark on this page knows your customers the way your own analytics do.

Turn These Statistics Into a Strategy That Works

Numbers like these are only useful if they change what you do on Monday morning. The throughline across all 35 is simple: audiences are fragmented, attention is the scarce resource, and the brands that win treat social as a data-driven, two-way relationship rather than a broadcast.

If you want to turn these stats into an actual plan, the next step is building a coordinated approach across your channels instead of optimizing each one in isolation.
