Social Media Statistics: Global Data and UK Insights

Social media crossed a meaningful threshold in 2024: more than five billion people worldwide now use at least one platform regularly, which works out to roughly 62% of the global population. For businesses in Northern Ireland, Ireland, and the UK, that figure matters less than what is happening closer to home — and the regional picture is more nuanced than global headlines suggest.

This guide brings together verified social media statistics from Ofcom, DataReportal, and Statista alongside platform-specific data for marketers and business owners who need practical benchmarks, not just headline numbers. Whether you’re deciding where to spend a modest social budget or trying to understand why your current approach isn’t converting, the numbers here will give you a clearer frame of reference.

2026 At-a-Glance: Key Global Benchmarks

Before getting into platform detail, it helps to establish what the global baseline actually looks like. The figures below, drawn from DataReportal’s Digital 2026 Global Overview Report, give you a reference point for everything that follows.

The multi-platform reality is the most significant shift for businesses planning content. Users do not live on one platform; they move between five, six, or seven. That has direct implications for where you invest production time and budget.

Global Social Media Usage: Growth and Demographics

The headline user numbers are well-publicised, but the detail beneath them is where the useful strategic insights sit. Growth has slowed, demographic profiles have shifted, and the assumptions many businesses made about who uses which platform are now outdated.

How Many People Use Social Media Worldwide?

Global social media users grew from approximately 4.9 billion in early 2024 to 5.24 billion by early 2026, according to DataReportal. That rate of growth has slowed compared to the 2019 to 2022 surge, suggesting platforms are increasingly competing for time with existing users rather than adding large volumes of new ones.

The demographic spread has also shifted. Platforms that were once youth-dominated have aged. Facebook’s largest active cohort in most Western markets is now 35 to 54. TikTok, by contrast, retains the youngest average age profile of any major platform, with a particularly strong concentration in the 16 to 24 bracket — though user growth in the 25 to 34 segment has been notable since 2023.

Average Time Spent by Platform

Daily usage time varies considerably by platform type. Short-form video platforms attract the longest daily sessions. According to DataReportal, users who access TikTok spend an average of 58 minutes per day on the app. YouTube averages around 48 minutes for active users. Facebook sits at approximately 33 minutes; Instagram at 30.

For businesses, these figures matter when matching content format to platform. A 90-second video has a reasonable chance of being watched on TikTok. The same video, posted as a LinkedIn article attachment, faces a very different set of audience expectations.

Social Media in the UK and Ireland: Regional Data

Global statistics give you context, but they rarely give you a usable plan. Most social media roundups default to US-centric data, leaving businesses in Northern Ireland, Ireland, and the wider UK to work from benchmarks that may not reflect their actual audiences. The regional picture here is worth examining in its own right.

UK Social Media Usage

Ofcom’s 2025 Online Nation report found that 89% of UK adults use at least one social media platform, with YouTube, Facebook, and Instagram remaining the three most-used platforms for adults overall. Notably, TikTok has overtaken Snapchat and X to sit fourth, used by 36% of UK adults — a figure that rises sharply to over 60% among 16 to 24-year-olds.

LinkedIn’s 29% reach understates its commercial relevance. Its users are, by definition, professionally oriented. For B2B services, professional services, and recruitment-heavy industries, LinkedIn often delivers higher conversion rates per impression than platforms with a considerably broader reach.

Ireland and Northern Ireland

The CSO Ireland’s Information Society Statistics 2024 found that 79% of Irish internet users aged 16 to 74 used social media — higher than the EU average of 71%. Facebook retains unusually strong penetration in Ireland compared to other markets, particularly among users over 35.

Northern Ireland’s social media habits track closely with the rest of the UK for platform choice, but usage intensity for community-focused platforms such as Facebook Groups and WhatsApp tends to be higher, reflecting patterns common to smaller regional markets where word-of-mouth and community networks carry significant commercial weight.

For businesses operating across both jurisdictions, this cross-border nuance has practical implications. A campaign optimised purely for the TikTok-first habits of 18 to 24-year-olds in Great Britain may need to be complemented by a stronger Facebook presence to reach comparable audiences in rural Northern Ireland or the Republic of Ireland.

Ciaran Connolly, founder of ProfileTree, puts it plainly: “The biggest mistake we see Northern Irish SMEs make is copying a social strategy they’ve seen work for a London-based brand. The audience composition here is different, the platforms that convert are sometimes different, and the content that resonates with local customers doesn’t always look like what the global case studies show.”

Social Search: The New Discovery Channel

One of the most commercially significant shifts in social media behaviour over the past two years has received relatively little attention in mainstream statistics roundups. Social platforms are no longer just places people go to share content — for a growing proportion of users, they are where the search process begins.

TikTok as a Search Engine

Adobe’s 2023 research found that 64% of Gen Z users — those born from 1997 to 2012 — use TikTok as a search engine. A separate finding from Google’s own internal research, cited by Search Engine Land, found that roughly 40% of young people in the US turn to TikTok or Instagram rather than Google when looking for a place to eat or a product to buy.

This has direct consequences for businesses managing their digital presence. A Belfast restaurant that ranks well on Google but has no TikTok presence is simply invisible to a significant segment of its potential customer base. The same applies to service businesses targeting younger decision-makers.

The Impact on Traditional SEO

Social search does not replace Google for transactional queries — people searching “accountant Northern Ireland” are still doing so on Google. Increasingly, what it replaces is the discovery phase. Users encounter brands, products, and services through social video, then validate those discoveries through Google searches or direct website visits.

This means a business’s social content strategy and its SEO strategy need to work in tandem. Content that introduces the brand on TikTok or Instagram Reels needs to feed back into a website that can rank and convert when that same user makes a considered search later in their journey. ProfileTree’s approach to digital marketing strategy accounts for this multi-touchpoint reality, mapping content formats to each stage of the awareness-to-conversion path.

Platform-Specific Statistics for 2026

Aggregate figures only go so far. Each platform has its own audience composition, content formats, and engagement patterns — and the gap between them is wide enough that a strategy built for one will not simply transfer to another. The breakdowns below focus on what is most relevant for businesses making practical allocation decisions.

Instagram

Instagram reached 2 billion monthly active users globally in 2024, according to Meta’s own reporting. Reels content receives, on average, 22% more interaction than static image posts, based on Socialinsider’s 2025 benchmark study. For business accounts, the average organic reach for a Reel sits at approximately 14% of followers — considerably higher than the 5 to 7% typical for static posts.

The platform continues to skew younger than Facebook, with its strongest engagement concentration in the 18 to 34 bracket. For consumer-facing businesses in hospitality, retail, fashion, beauty, and food, Instagram remains the most commercially efficient organic platform in the UK and Irish markets.

TikTok

TikTok reported 1.7 billion monthly active users globally in 2025. In the UK, it is now used by more than 20 million adults. Its average daily session length of 58 minutes is the highest of any major platform.

TikTok’s UK statistics reveal a platform that has matured beyond its teenage roots. The 25 to 34 age group is now TikTok’s fastest-growing user segment in the UK, and the platform’s own data shows purchase intent among users who discover products through TikTok content is higher than on any other social platform.

For businesses considering a video production investment, TikTok’s performance characteristics favour authentic, low-production content, with implications for budget allocation. A polished 90-second brand video may underperform a 30-second phone-shot clip, depending on the audience and product category.

LinkedIn

LinkedIn reported 1 billion members globally in 2024, with 37 million in the UK. B2B marketers consistently rank it as their highest-performing platform for lead generation. HubSpot’s 2025 State of Marketing report found that LinkedIn generates three times more B2B leads than Facebook or X.

For professional services firms, technology companies, and recruitment businesses in Northern Ireland and Ireland, LinkedIn is not optional. LinkedIn’s industry data shows which sectors see the most active engagement, and the platform’s targeting options for paid campaigns — by job title, company size, and seniority — make it the most precise paid social tool available for B2B.

YouTube

YouTube reached 2.7 billion logged-in monthly users globally according to Google’s 2025 figures. In the UK, Ofcom data shows it is the most-used social platform among adults of all ages, surpassing Facebook. Its unique position as both a social platform and the world’s second-largest search engine makes it valuable in a way that other platforms are not: content can continue to generate views and leads years after publication.

For businesses investing in video production, YouTube should sit at the top of the distribution hierarchy. A well-produced explainer or case study video hosted on YouTube can surface in Google search results, drive referral traffic to a website, and be repurposed across other platforms — making it one of the strongest long-term content assets a business can build.

Facebook

Despite a decade of predictions about its decline, Facebook remains the most-used social platform among UK adults over 35 (Ofcom 2025). Its community and group features drive particularly high engagement in local and regional contexts. For businesses targeting consumers aged 35 and above, or running hyper-local campaigns in specific towns or areas, Facebook Groups and local advertising remain highly effective.

Facebook’s organic reach for business pages has continued to fall — most accounts now see less than 5% organic reach on standard posts. This makes it primarily a paid platform for new customer acquisition, with organic content playing a secondary role in retention.

Threads and X

The micro-blogging space has fragmented since X’s rebranding. Threads, Meta’s text-based platform, reached 300 million monthly active users by late 2024. X retains a specific audience — journalists, public affairs professionals, and real-time news followers — but its advertising effectiveness has declined significantly since 2022. For most SMEs, neither platform warrants primary investment until a clearer picture of their long-term user trajectories emerges.

The AI Impact: Content Volume and User Trust

The scale of AI-generated content entering social feeds has increased sharply since 2023, and user attitudes toward it are beginning to influence how content performs. This is not a future concern — it is already showing up in engagement data, and businesses producing social content need to account for it now.

AI-generated content now constitutes a measurable share of what appears in social feeds. Adobe’s 2024 Content Authenticity research found that 38% of consumers surveyed said they were less likely to engage with content they believed to be AI-generated. That trust gap narrows considerably when AI-assisted content is transparent and well-produced.

For businesses, the practical implication is not to avoid AI tools in content production — most professional teams now use them for scripting, captioning, and scheduling — but to ensure the content retains a human voice, perspective, and visual authenticity. Audiences respond to specificity and genuine expertise. Generic AI-generated content, identifiable by its uniform tone and vague claims, underperforms compared to content that conveys a real point of view.

The rise of AI content detection tools has also made authenticity a measurable factor in content strategy, rather than simply an aesthetic preference.

Social Media Marketing Benchmarks for Businesses

Raw platform statistics tell you where audiences spend their time. Engagement benchmarks tell you what realistic performance looks like once you are actually publishing. The two sets of data together are what make a social strategy defensible rather than aspirational.

Engagement Rate Benchmarks (2025, Socialinsider)

Engagement rate benchmarks are frequently misread by small businesses. A 0.4% LinkedIn engagement rate sounds low compared to TikTok’s 4.1%, but the commercial quality of that engagement — from senior decision-makers, potential B2B clients, and industry contacts — is structurally different. The metric that matters is not engagement rate in isolation but what that engagement leads to.

Social Commerce

Meta’s 2025 shopping data found that 56% of UK Instagram users have made a purchase after seeing a product on the platform. TikTok Shop’s UK gross merchandise volume grew by over 80% year on year in 2024, making it the fastest-growing e-commerce channel in the country.

For product-based businesses, social commerce is no longer a secondary channel. A well-structured digital marketing strategy that integrates organic content, paid targeting, and shoppable posts can significantly reduce the gap between discovery and purchase.

What These Statistics Mean for Your Social Strategy

Statistics are only useful if they inform a decision. The data above points to a few consistent conclusions that apply across most SME contexts in Northern Ireland, Ireland, and the UK — regardless of sector or budget.

Platform selection should follow audience data, not trend headlines. If your customers are primarily 40-plus local consumers, Facebook and YouTube will almost certainly outperform TikTok, regardless of the global growth figures.

Content format drives reach more than posting frequency on most platforms. One well-produced Reel per week typically outperforms five static posts. This matters for businesses with limited production resources — video production investment tends to deliver stronger returns when concentrated on fewer, higher-quality outputs rather than spread thinly across daily posting schedules.

Social search is a genuine business consideration now. If your business category — food, fitness, beauty, local services — is one where younger consumers make decisions through social discovery, a TikTok or Instagram presence is not optional. The question is: what level of resources is proportionate to the opportunity?

Analytics matter more than volume. Time spent on social media statistics across platforms tells you where audiences are, but your own account analytics tell you where your specific customers are. Decisions based on platform-level data should always be tested against your actual audience behaviour.
