Top Digital and Social Media Trends in South Korea in 2026

South Korea is one of the most digitally advanced countries in the world. In 2026, nearly 98% of its population uses the internet, over 49 million people are active on social media, and mobile connectivity exceeds 100% of the total population. If your brand wants to reach Korean audiences, understanding these numbers is essential.

The “State of Digital” in South Korea in 2026

South Korea’s digital ecosystem in 2026 is impressively connected. Here are the essential headline numbers:

• 60.9 million cellular mobile connections were active in South Korea in late 2025 — equivalent to 118% of the total population.
• 50.6 million individuals used the internet, putting online penetration at 97.9%.
• 49.3 million social media user identities were recorded, equating to 95.4% of the total population.

These numbers make South Korea one of the most “wired” nations on Earth. For businesses looking to enter or expand in this market, a localised digital strategy is no longer optional — it is a necessity. Understanding how Korean consumers behave online is the first step to meaningful engagement.

Population of South Korea in 2026

According to United Nations data, the population of South Korea stood at 51.7 million in October 2025. South Korea’s population has been gently declining — it decreased by approximately 55,000 people (-0.1%) between the end of 2024 and the end of 2025.

In terms of geography and gender, 81.6% of the population lives in urban centres, whilst 18.4% reside in rural areas. At the same time, 50.1% of the population is female and 49.9% is male.

South Korea’s Population by Age

South Korea has a notably ageing population. The median age is 45.6, which means half the population is above this age. Here is how the population breaks down by age group, according to UN data:

• 0–4 years: 2.4%
• 5–12 years: 6.0%
• 13–17 years: 4.5%
• 18–24 years: 7.0%
• 25–34 years: 13.7%
• 35–44 years: 13.8%
• 45–54 years: 15.9%
• 55–64 years: 16.3%
• 65 and above: 20.3%

This age profile has a direct impact on digital marketing. Older age groups (45–64) make up a significant share of the population, meaning brands must balance digital content for younger, mobile-first users alongside platforms popular with older demographics such as KakaoTalk and Facebook.

For brands wishing to connect with Korean-speaking audiences in their native language, Elite Asia’s Korean translation and interpretation services ensure your message is accurate, culturally relevant, and effective.

Mobile Connections in South Korea in 2026

GSMA Intelligence data shows that South Korea had 60.9 million cellular mobile connections at the end of 2025 — equivalent to 118% of the total population. This high ratio is not unusual, as many people hold more than one SIM card or eSIM for personal and professional use.

The mobile connection count grew by 169,000 (+0.3%) during 2025. More notably, 99.6% of all mobile connections in South Korea are classified as “broadband”, meaning they connect via 3G, 4G, or 5G networks.

With 92% of South Koreans accessing the internet primarily through mobile devices, South Korea is firmly a mobile-first market. This means mobile-optimised content, fast-loading pages, and app-based experiences are not just best practice — they are the baseline expectation. As you develop your regional digital strategy, understanding what SEO means and how it works in a mobile-first environment is a strong starting point.

Internet Use in South Korea in 2026

Kepios analysis indicates that there were 50.6 million internet users in South Korea in October 2025, putting the internet penetration rate at 97.9% of the total population. This places South Korea among the top nations globally for connectivity.

Approximately 1.09 million people — just 2.1% of the population — were still “offline” at the end of the year. Meanwhile, 97.5% of South Korea’s entire internet user base used at least one social media platform.

The dominance of Naver as a local search engine (holding over two-thirds of search market share) means that businesses targeting Korean audiences must look beyond Google. Naver’s search results blend blogs, news, shopping, and direct answers on a single page, requiring a distinctly localised SEO approach. Learn how building strong backlinks and SEO fundamentals can elevate your brand’s visibility in competitive markets like South Korea.

Internet Connection Speeds in South Korea in 2026

South Korea is globally renowned for its internet infrastructure, and 2026 data confirms this reputation. According to Ookla, internet users in South Korea could expect the following speeds at the end of 2025:

• Median mobile internet download speed (via cellular): 224.54 Mbps
• Median fixed internet download speed: 233.15 Mbps

These speeds represent remarkable year-on-year growth. Mobile internet download speed increased by 83.31 Mbps (+59.0%) in the twelve months to August 2025, whilst fixed internet speed increased by 75.52 Mbps (+47.9%) during the same period.

Such fast, reliable connections shape Korean user behaviour significantly. High-definition video streaming, real-time live commerce, interactive AR campaigns, and AI-driven personalisation all perform seamlessly in this environment — meaning brands operating in Korea can leverage rich media content without the friction seen in lower-bandwidth markets.

Social Media Statistics for South Korea in 2026

South Korea’s social media landscape is both diverse and deeply engaged. Kepios analysis indicates that there were 49.3 million active social media user identities in South Korea in October 2025, equivalent to 95.4% of the total population.

Social media user identities grew by 367,000 (+0.8%) between late 2024 and the end of 2025. There were 45.4 million user identities aged 18 and above on social media — a figure equivalent to 100.9%* of the adult population, reflecting the scale of multi-platform usage.

Gender distribution across social media in South Korea was nearly balanced: 49.6% female and 50.4% male. KakaoTalk dominates daily communication, whilst YouTube leads in content consumption and entertainment — together making up the backbone of South Korea’s social media ecosystem. Short-form video, AI-driven personalisation, and social commerce are among the fastest-growing trends reshaping how brands connect with consumers in 2026.

To succeed in this landscape, localising your content for Korean platforms and audiences is essential. Explore how Elite Asia’s digital marketing solutions can help your brand cut through the noise in South Korea.

KakaoTalk Users in South Korea in 2026

KakaoTalk is the beating heart of South Korea’s digital communication. Figures from Kakao’s earnings presentations indicate that KakaoTalk had 49.1 million monthly active users in South Korea — equivalent to 95.1% of the country’s total population. An extraordinary 97.1% of all South Korean internet users are also active KakaoTalk users.

For context, a 2025 Korea Press Foundation survey found that 98.9% of respondents reported using KakaoTalk — making it by far the most used platform in the country. KakaoTalk’s audience is almost evenly split: 48.9% female and 51.1% male.

KakaoTalk User Growth in South Korea

KakaoTalk’s user base in South Korea increased by 403,000 (+0.8%) between Q2 2024 and Q2 2025. On a quarterly basis, active users grew by 145,000 (+0.3%) between Q1 and Q2 2025.

Whilst this growth is steady rather than explosive, it reflects KakaoTalk’s status as a mature, near-universal platform. Its role has evolved well beyond messaging — KakaoTalk now encompasses payments (KakaoPay), shopping, news, and branded channels, making it a full-stack marketing ecosystem in its own right. For B2B marketers, KakaoTalk’s official business accounts offer a direct line to Korean professionals and consumers. Reaching Korean audiences starts with speaking their language — discover Elite Asia’s Korean language services to support your KakaoTalk channel strategy.

YouTube Users in South Korea in 2026

YouTube is South Korea’s dominant platform for video content. Google’s advertising resources indicate that YouTube had 42.9 million users in South Korea in late 2025, equivalent to 83.1% of the total population. YouTube ads reached 84.8% of South Korea’s total internet user base.

Data from IGAWorks’ Mobile Index also shows that YouTube recorded the highest monthly active users (MAU) among major social media platforms throughout 2025, growing from 47.03 million in January to 48.48 million by November — a 3.1% increase. This makes YouTube the single most-used social media app in South Korea by MAU, ahead of KakaoTalk.

YouTube User Growth in South Korea

Google’s ad planning tools show that YouTube’s potential ad reach in South Korea decreased by 500,000 (-1.2%) between the end of 2024 and late 2025, with a further decrease of 600,000 (-1.4%) in Q3 2025. However, it is important to note that ad reach figures and actual MAU figures can differ significantly — with MAU data from IGAWorks showing continued growth.

YouTube’s dominance aligns with broader trends: South Korean users consume 51% of their news via YouTube, and live-streaming accounts for a large share of online content. Short-form content through YouTube Shorts is also gaining ground. Understanding how SEO and content strategy work together is key for brands looking to rank on both Google and Naver-linked YouTube results.

Facebook Users in South Korea in 2026

Facebook’s presence in South Korea has been declining, particularly among younger users. Meta’s advertising resources indicate that Facebook had 7.05 million users in South Korea in late 2025. By MAU data from IGAWorks, Facebook fell from 8.61 million in January 2025 to 8.09 million in November — a 6% decline.

Facebook’s ad reach equated to just 13.6% of the total population at the end of 2025. Amongst adults aged 18 and above, 15.7% used the platform.

Facebook User Growth in South Korea

Facebook’s potential ad reach in South Korea decreased by 600,000 (-7.8%) between October 2024 and October 2025. A further decrease of 400,000 (-5.4%) was recorded in Q3 2025 alone.

This continuing decline reflects a generational shift — college students now overwhelmingly prefer Instagram over Facebook, with the latter recording only a 5.3% usage rate among university students surveyed in early 2026.

Facebook Adoption in South Korea

Despite its decline, Facebook retains a foothold among users aged 35 and above. Its gender split skews heavily male, with 61.7% male and 36.2% female adult users. For B2B campaigns targeting mid-career professionals or older consumer demographics, Facebook still offers a supplementary channel — though it should not be the primary focus of a Korea-focused digital strategy.

Instagram Users in South Korea in 2026

Instagram is one of South Korea’s fastest-growing social platforms. Meta’s advertising tools indicate that Instagram had 25.6 million users in South Korea in late 2025 — equivalent to 49.5% of the total population. Among adults aged 18 and above, 55.1% used the platform.

Notably, a 2026 survey by the Korean Women’s Development Institute found that Instagram ranked as the number one platform among South Korean university students, with 81.1% usage — surpassing even KakaoTalk (70.3%). Instagram’s female-skewed audience (55.2% female, 43.8% male) makes it a strong channel for beauty, fashion, food, and lifestyle brands.

Instagram User Growth in South Korea

Instagram’s ad reach in South Korea grew by an impressive 2.95 million (+13.1%) between October 2024 and October 2025. On a quarterly basis, it grew by a further 300,000 (+1.2%) in Q3 2025.

IGAWorks’ MAU data confirms this trajectory — Instagram grew from 22.98 million users in January 2025 to 24.68 million by November, a 7.4% rise. Instagram’s popularity is fuelled by Reels, shopping integrations, and its role as a visual discovery engine — all of which resonate strongly with South Korea’s highly aesthetic and trend-conscious consumer culture. Brands entering South Korea should prioritise localised Korean content to connect authentically with Instagram’s young, engaged audience.

TikTok Users in South Korea in 2026

TikTok is the biggest growth story in South Korea’s 2026 social media landscape. TikTok’s advertising resources indicate the platform had 11.8 million users aged 18 and above in South Korea in late 2025, reaching 26.2% of all adults. Its internet user reach stood at 23.4%.

Wiseapp data from August 2025 placed TikTok at 8.32 million monthly active users, with TikTok Lite adding a further 6.17 million — together making a significant combined presence. TikTok’s audience in South Korea skews slightly male: 54.2% male versus 45.8% female.

TikTok User Growth in South Korea

TikTok’s ad reach in South Korea exploded by 4.85 million (+69.6%) between late 2024 and late 2025. In Q3 2025 alone, reach grew by 3.98 million (+50.7%). IGAWorks data also showed TikTok Lite growing by 28.7% from January to November 2025.

This growth is driven by K-pop culture, viral challenges, and a surge in creator-led commerce. Short-form videos now account for 72% of all digital content consumption in South Korea. For B2C brands, TikTok has rapidly become a must-have platform in any South Korea campaign. For B2B marketers, TikTok’s growing professional content niche is also worth monitoring. Discover how a localised digital marketing strategy can help your brand capitalise on TikTok’s momentum in South Korea.

LinkedIn Users in South Korea in 2026

LinkedIn has been growing steadily in South Korea, particularly as the country’s professional class becomes more globally connected. LinkedIn’s advertising resources indicate the platform had 5.00 million members in South Korea in late 2025, representing 9.7% of the total population.

Among adults aged 18 and above, LinkedIn ads reached 11.1% of South Korea’s population. Uniquely, LinkedIn’s gender split in South Korea is perfectly balanced at 50% female and 50% male. Note that LinkedIn reports total registered members rather than monthly active users, so these figures may overstate active engagement.

LinkedIn User Growth in South Korea

LinkedIn’s potential ad reach in South Korea increased by 600,000 (+13.6%) between the end of 2024 and the end of 2025. On a quarterly basis, it grew by a further 100,000 (+2.0%) in Q3 2025.

For B2B marketers, LinkedIn’s steady growth in South Korea is a positive signal. South Korean professionals are increasingly using the platform for networking, employer branding, and thought leadership. As English-language content remains common on LinkedIn, investing in professional Korean translation for your LinkedIn posts can significantly improve engagement with local audiences.

Messenger Users in South Korea in 2026

Meta’s Messenger has a limited but existing presence in South Korea. Meta’s advertising resources show that Messenger’s ad reach stood at 2.05 million users in South Korea in late 2025 — equivalent to 4.0% of the total population. Among adults, just 4.6% used the platform.

Messenger’s audience in South Korea is predominantly male: 63.4% male versus 34.6% female.

Messenger User Growth in South Korea

Messenger’s ad reach in South Korea decreased by 250,000 (-10.9%) between October 2024 and October 2025. A further decline of 100,000 (-4.7%) occurred in Q3 2025.

Given that KakaoTalk provides a deeply embedded domestic messaging alternative with far superior reach, Messenger faces an extremely challenging environment in South Korea. Its declining trajectory suggests it is not a priority channel for brands targeting the Korean market.

Reddit Users in South Korea in 2026

Reddit is an emerging platform in South Korea. Data from Reddit’s advertising resources indicates the platform had 5.85 million users in South Korea in late 2025, equivalent to 11.3% of the total population. Reddit’s ad reach covered 11.6% of South Korea’s internet user base.

Reddit User Growth in South Korea

Reddit’s ad reach in South Korea recorded a staggering increase of 5.12 million (+699%) between late 2024 and late 2025. On a quarterly basis, reach grew by 3.10 million (+113%) in Q3 2025 alone.

It is important to approach these figures with caution — as DataReportal notes, these changes may reflect updates to Reddit’s ad planning tool methodology rather than actual shifts in user behaviour. Nevertheless, Reddit’s growing global footprint and its popularity for niche tech, gaming, and K-culture communities suggests it is worth monitoring for brands targeting younger, digitally savvy Korean consumers. Pairing Reddit activity with a broader content strategy built on sound SEO principles can amplify organic reach.

X Users in South Korea in 2026

X (formerly Twitter) maintains a notable presence in South Korea, particularly for real-time conversations, news, and K-pop fan communities. X’s advertising resources indicate the platform had 10.4 million users in South Korea in late 2025, equivalent to 20.1% of the total population. Among adults, 21.2% were X users.

A 2026 survey of university students found X ranked fourth in platform usage at 25.9% — significantly behind Instagram, YouTube, and KakaoTalk but ahead of TikTok (8.5%) and Facebook (5.3%) in that demographic. X’s reported gender split suggests 65.6% female and 34.3% male — though DataReportal advises caution as X infers gender from user signals rather than self-reported data.

X User Growth in South Korea

X’s ad reach in South Korea decreased by 120,000 (-1.1%) between the end of 2024 and late 2025. However, the data also shows a quarterly increase of 260,000 (+2.6%) between July and October 2025. IGAWorks’ MAU data confirms modest growth — X rose from 6.67 million users in January 2025 to 7.19 million in November, a 7.8% increase.

X remains a relevant channel in South Korea, particularly for brands in entertainment, tech, and current affairs. It is especially powerful during live events and cultural moments such as K-pop comebacks, sports, and political discussions.

Threads Users in South Korea in 2026

Threads — Meta’s text-based social network — is gaining ground in South Korea. Meta’s advertising tools indicate that Threads had 4.40 million users in South Korea in late 2025, equivalent to 8.5% of the total population. Among adults, 9.7% used the platform, with a nearly even gender split: 50.6% female and 49.4% male.

IGAWorks data shows Threads grew from 4.80 million users in January 2025 to 5.87 million by November — a strong 22.3% increase over the year. Whilst Threads is still early in its growth cycle in South Korea, its integration with Instagram’s user base and its appeal for casual, text-led conversation gives it a solid foundation. Brands active on Instagram should consider extending their presence to Threads as part of a unified Meta strategy. For B2B audiences, Threads can serve as a complementary channel for sharing industry insights and brand stories alongside LinkedIn and X.
