You’ll also find the complete Digital 2023 report on South Korea in the “full report” section below, but let’s start by taking a look at the key numbers for South Korea this year.
The state of digital in South Korea in 2023
Here are the essential headlines for digital adoption and use in South Korea in early 2023:
There were 50.56 million internet users in South Korea at the start of 2023, when internet penetration stood at 97.6 percent.
South Korea was home to 47.64 million social media users in January 2023, equating to 92.0 percent of the total population.
A total of 64.19 million cellular mobile connections were active in the Republic of Korea in early 2023, with this figure equivalent to 123.9 percent of the total population.
These headline stats offer a great overview of the “state of digital” in the Republic of Korea, but in order to make sense of how digital trends and behaviours are evolving, we need to dig deeper into the data.
Let’s take a closer look at what the latest numbers tell us, starting with some valuable context relating to the Republic of Korea’s population.
South Korea’s population in 2023
The Republic of Korea’s total population was 51.80 million in January 2023.
Data shows that South Korea’s population decreased by 26 thousand (-0.05 percent) between 2022 and 2023.
50.1 percent of the Republic of Korea’s population is female, while 49.9 percent of the population is male.
At the start of 2023, 81.5 percent of the Republic of Korea’s population lived in urban centres, while 18.5 percent lived in rural areas.
Note: gender data are currently only available for “female” and “male”.
South Korea’s population by age
The median age of the Republic of Korea’s population is 44.4.
Here’s how the Republic of Korea’s total population breaks down by age group:
2.9 percent is between the ages of 0 and 4.
6.7 percent is between the ages of 5 and 12.
4.4 percent is between the ages of 13 and 17.
7.6 percent is between the ages of 18 and 24.
13.6 percent is between the ages of 25 and 34.
14.5 percent is between the ages of 35 and 44.
16.4 percent is between the ages of 45 and 54.
16.0 percent is between the ages of 55 and 64.
17.9 percent is aged 65 and above.
Note: percentages may not sum to 100 percent due to rounding.
Internet use in South Korea in 2023
There were 50.56 million internet users in the Republic of Korea in January 2023.
The Republic of Korea’s internet penetration rate stood at 97.6 percent of the total population at the start of 2023.
Kepios analysis indicates that internet users in South Korea decreased by 26 thousand (-0.05 percent) between 2022 and 2023.
For perspective, these user figures reveal that 1.24 million people in South Korea did not use the internet at the start of 2023, suggesting that 2.4 percent of the population remained offline at the beginning of the year.
However, complexities associated with the collection and analysis of internet user data mean that it can often take several months before research is ready for publication. As a result, the latest published figures for internet use invariably under-represent reality, and actual adoption and growth may be higher than the figures shown here suggest. Please see our comprehensive notes on data for further details.

Internet connection speeds in South Korea in 2023
Data published by Ookla indicate that internet users in South Korea could have expected the following internet connection speeds at the start of 2023:
Median mobile internet connection speed via cellular networks: 118.76 Mbps.
Median fixed internet connection speed: 95.34 Mbps.
Ookla’s data reveals that the median mobile internet connection speed in the Republic of Korea increased by 13.79 Mbps (+13.1 percent) in the twelve months to the start of 2023.
Meanwhile, Ookla’s data shows that fixed internet connection speeds in South Korea decreased by 3.52 Mbps (-3.6 percent) during the same period.
Social media statistics for South Korea in 2023
There were 47.64 million social media users in South Korea in January 2023.
This figure might seem quite different to the values that we published in previous years, but please note that the sources we use to inform and calculate our social media user numbers have made important and wide-ranging revisions to their data over recent months.
These adjustments to source data mean that our latest numbers are not comparable with equivalent figures that we published in previous years, and readers should not regard any differences in these numbers as an actual change in social media use.
Indeed, our analysis of various data points from trusted third parties such as GWI and data.ai shows that there has been no discernible drop in overall social media use, and in almost all countries, social media use continues to increase.
As a result, readers should view any such differences as “corrections” in the data, and not as an indication that social media adoption has declined.
The number of social media users in South Korea at the start of 2023 was equivalent to 92.0 percent of the total population, but it’s also important to note that social media users may not represent unique individuals (see our detailed notes on data to learn why).
Meanwhile, data published in the ad planning tools of top social media platforms indicates that there were 40.80 million users aged 18 and above using social media in South Korea at the start of 2023, which was equivalent to 91.6 percent of the total population aged 18 and above at that time.
More broadly, 94.2 percent of the Republic of Korea’s total internet user base (regardless of age) used at least one social media platform in January 2023.
At that time, 50.0 percent of South Korea’s social media users were female, while 50.0 percent were male.
Note: due to significant revisions in source data, we regret that we’re currently unable to provide reliable figures for the year-on-year change in social media users in South Korea. We recommend that readers do not compare our latest figures for social media use with figures published in our previous reports, because such comparisons will deliver inaccurate results.
KakaoTalk users in South Korea
Numbers published in KakaoTalk’s investor earnings announcement reveal that the platform had 47.64 million monthly active users in South Korea at the start of 2023.
This figure equates to 92.0 of South Korea’s total population, but it’s worth stressing that this figure may include duplicate accounts (see our notes on data to learn more).
For perspective, the company’s monthly active user figures suggest that 94.2 percent of South Korean internet users were active on KakaoTalk at the start of 2023.
KakaoTalk was South Korea’s top social media platform by active user numbers in early 2023, but it’s worth highlighting that the country accounted for 88.9 percent of the platform’s total global active user base at this time.
Facebook users in South Korea in 2023
Data published in Meta’s advertising resources indicates that Facebook had 9.60 million users in the Republic of Korea in early 2023.
However, Meta has made important changes to the way its advertising resources report audience reach data over recent months – including making significant revisions to its base audience data for Facebook – so the figures shown here may not be directly comparable with figures published in our previous reports.
To learn more about these changes, please see this article, as well as our comprehensive notes on data.
Facebook user growth in the Republic of Korea
Figures published in Meta’s own tools indicate that Facebook’s potential ad reach in the Republic of Korea decreased by 1.1 million (-9.9 percent) between 2022 and 2023.
For more recent context, the same data show that the number of users that marketers could reach with ads on Facebook in the Republic of Korea decreased by 250 thousand (-2.5 percent) between October 2022 and January 2023.
However, it’s important to stress that these advertising reach figures are not the same as the monthly active users figures that Meta reports in its investor earnings announcements, and they should not be interpreted as such.
As the company states within its ad planning tools,
“Estimated audience size is not a proxy for monthly or daily active users, or for engagement. Estimates aren’t designed to match population, census estimates or other sources, and may differ depending on factors such as how many accounts across Meta technologies a person has, how many temporary visitors are in a particular geographic location at a given time, and Meta user-reported demographics.”
As a result, changes in ad reach may not necessarily indicate any change in the platform’s overall user base.
But despite these caveats, Meta’s ad reach data still offers valuable insights into how Facebook use is evolving.
Facebook adoption in the Republic of Korea
Facebook’s ad reach in South Korea was equivalent to 18.5 percent of the total population at the start of 2023.
However, Facebook restricts the use of its platform to people aged 13 and above, so it’s worth highlighting that 20.5 percent of the “eligible” audience in South Korea uses Facebook in 2023.
For additional context, Facebook’s ad reach in the Republic of Korea was equivalent to 19.0 percent of the local internet user base (regardless of age) in January 2023.
At the start of 2023, 39.4 percent of Facebook’s ad audience in South Korea was female, while 60.6 percent was male.
Note: Meta’s advertising resources only publish audience gender data for “female” and “male” users.

YouTube users in South Korea in 2023
Updates to Google’s advertising resources indicate that YouTube had 46.00 million users in the Republic of Korea in early 2023.
It’s important to stress that these advertising reach figures do not necessarily represent the same thing as monthly active user figures though, and there may be meaningful differences between the size of YouTube’s ad audience and its total active user base.
However, the company’s own data suggests that YouTube’s ad reach in early 2023 was equivalent to 88.8 percent of the Republic of Korea’s total population at the start of the year.
To put those figures in perspective, YouTube ads reached 91.0 percent of South Korea’s total internet user base (regardless of age) in January 2023.
At that time, 50.0 percent of YouTube’s ad audience in South Korea was female, while 50.0 percent was male.
Note: Google’s advertising resources only publish audience gender data for “female” and “male” users.
YouTube user growth in the Republic of Korea
Data published in Google’s own ad planning tools show that YouTube’s potential ad reach in the Republic of Korea decreased by 400 thousand (-0.9 percent) between the start of 2022 and early 2023.
Meanwhile, the same data show that the number of users that marketers could reach with ads on YouTube in the Republic of Korea decreased by 100 thousand (-0.2 percent) between October 2022 and January 2023.

Instagram users in South Korea in 2023
Numbers published in Meta’s advertising tools indicate that Instagram had 19.25 million users in the Republic of Korea in early 2023.
The company’s recently revised figures suggest that Instagram’s ad reach in South Korea was equivalent to 37.2 percent of the total population at the start of the year.
However, Instagram restricts the use of its platform to people aged 13 and above, so it’s helpful to know that 41.1 percent of the “eligible” audience in the Republic of Korea uses Instagram in 2023.
It’s also worth noting that Instagram’s ad reach in South Korea at the start of 2023 was equivalent to 38.1 percent of the local internet user base (regardless of age).
In early 2023, 54.9 percent of Instagram’s ad audience in the Republic of Korea was female, while 45.1 percent was male.
Note: Meta’s advertising resources only publish audience gender data for “female” and “male” users.
Instagram user growth in the Republic of Korea
Data published in Meta’s planning tools show that Instagram’s potential ad reach in the Republic of Korea decreased by 1.4 million (-6.8 percent) between 2022 and 2023.
On a quarterly basis, the company’s data also reveal that the size of Instagram’s ad audience in the Republic of Korea decreased by 750 thousand (-3.8 percent) between October 2022 and January 2023.
As we noted in the Facebook section above though, changes in the audience reach figures published in Meta’s ad planning tools do not necessarily correlate with overall changes in its platforms’ active user bases.

TikTok users in South Korea in 2023
Figures published in ByteDance’s advertising resources indicate that TikTok had 5.66 million users aged 18 and above in the Republic of Korea in early 2023.
Note that ByteDance allows marketers to target TikTok ads to users aged 13 and above via its advertising tools, but these tools only show audience data for users aged 18 and above.
For context, ByteDance’s figures indicate that TikTok ads reached 12.7 percent of all adults aged 18 and above in South Korea at the start of 2023.
Meanwhile, TikTok’s ad reach in the Republic of Korea was equivalent to 11.2 percent of the local internet user base at the beginning of the year, regardless of age.
In early 2023, 58.0 percent of TikTok’s ad audience in South Korea was female, while 42.0 percent was male.
Note: ByteDance’s advertising resources only publish audience gender data for “female” and “male” users.
TikTok user growth in the Republic of Korea
Data published in ByteDance’s own ad planning tools show that TikTok’s potential ad reach in the Republic of Korea increased by 763 thousand (+15.6 percent) between the start of 2022 and early 2023.
Meanwhile, figures indicate that the potential reach of ads on TikTok in the Republic of Korea decreased by 407 thousand (-6.7 percent) between October 2022 and January 2023.
Having said that, ad audiences often only account for a subset of a platform’s total users, and given that TikTok’s ad tools only publish data for users aged 18 and above, it’s important to remember that these changes in TikTok ad reach may not necessarily match changes in the platform’s overall user base.

Facebook Messenger users in South Korea in 2023
Data published in Meta’s advertising resources indicate that ads on Facebook Messenger reached 3.90 million users in the Republic of Korea in early 2023.
The company’s recently revised audience numbers suggest that Facebook Messenger’s ad reach in the Republic of Korea was equivalent to 7.5 percent of the total population at the start of the year.
Facebook Messenger restricts the use of its platform to people aged 13 and above though, so it’s also worth highlighting that ads reach 8.3 percent of Facebook Messenger’s “eligible” audience in South Korea in 2023.
For additional context, Facebook Messenger’s ad reach in the Republic of Korea is equivalent to 7.7 percent of the local internet user base (regardless of age).
At the start of 2023, 39.7 percent of Facebook Messenger’s ad audience in South Korea was female, while 60.3 percent was male.
Notes: Meta’s advertising resources only publish audience gender data for “female” and “male” users.
Facebook Messenger user growth in the Republic of Korea
Data published in Meta’s planning tools show that Facebook Messenger’s potential ad reach in the Republic of Korea decreased by 550 thousand (-12.4 percent) between 2022 and 2023.
On a quarterly basis, the company’s data reveal that the size of Facebook Messenger’s ad audience in the Republic of Korea decreased by 150 thousand (-3.7 percent) between October 2022 and January 2023.
However, as we noted in the Facebook section above, changes in the audience reach figures published in Meta’s ad planning tools do not necessarily correlate with overall changes in its platforms’ active user bases.

LinkedIn users in South Korea in 2023
Figures published in LinkedIn’s advertising resources indicate that LinkedIn had 3.50 million “members” in the Republic of Korea in early 2023.
However, note that LinkedIn’s advertising tools publish audience reach data based on total registered members, rather than the monthly active users that form the basis of the ad reach figures published by most other social media platforms.
As a result, these LinkedIn figures are not directly comparable with the figures for other social media platforms published on this page, or in our Digital 2023 reports.
The company’s advertising reach figures suggest that LinkedIn’s audience in South Korea was equivalent to 6.8 percent of the total population at the start of 2023.
LinkedIn restricts the use of its platform to people aged 18 and above though, so it’s also helpful to know that 7.9 percent of the “eligible” audience in the Republic of Korea uses LinkedIn in 2023.
For additional context, LinkedIn’s ad reach in South Korea was equivalent to 6.9 percent of the local internet user base (regardless of age) at the start of the year.
In early 2023, 49.5 percent of LinkedIn’s ad audience in the Republic of Korea was female, while 50.5 percent was male.
Note: LinkedIn’s advertising resources only publish audience gender data for “female” and “male” users.
LinkedIn user growth in the Republic of Korea
Data published in LinkedIn’s planning tools show that LinkedIn’s potential ad reach in the Republic of Korea increased by 300 thousand (+9.4 percent) between 2022 and 2023.
On a quarterly basis, the company’s data reveal that the size of LinkedIn’s ad audience in the Republic of Korea increased by 100 thousand (+2.9 percent) between October 2022 and January 2023.
However, because LinkedIn’s ad audience figures are based on total registered members rather than monthly active users, it’s unclear whether these trends might reflect changes in active LinkedIn use too.

Twitter users in South Korea in 2023
Numbers published in Twitter’s advertising resources indicate that Twitter had 9.80 million users in South Korea in early 2023.
This figure means that Twitter’s ad reach in South Korea was equivalent to 18.9 percent of the total population at the time.
However, it’s important to stress that these advertising reach figures are not the same as monthly active user figures, and there may be meaningful differences between the size of Twitter’s ad audience and its total active user base.
It’s also worth noting that Twitter restricts the use of its platform to people aged 13 and above, so these figures suggest that 20.9 percent of the “eligible” audience in the Republic of Korea uses Twitter in 2023.
For additional context, Twitter’s ad reach in South Korea was equivalent to 19.4 percent of the local internet user base (regardless of age) at the start of the year.
In early 2023, the company’s own data indicated that 68.6 percent of Twitter’s ad audience in South Korea was female, while 31.4 percent was male.
However, it’s worth noting that Twitter infers its users’ gender, by analysing signals such as the name that users enter in their profile, and their broader activity on the platform.
This contrasts with the gender data offered in the advertising tools of platforms like Facebook, which relies on the gender that users themselves enter in their own profile.
Moreover, our analysis suggests that Twitter’s inferences may not be particularly reliable in determining users’ gender, especially in countries where English is not the dominant language.
For example, consumer research findings published by GWI often offer quite a different picture of Twitter use by gender compared with Twitter’s own audience data.
But the apparent distortions that frequently appear in Twitter’s inferred gender data may be due in large part to the high number of “non-human” accounts that feature in Twitter’s active user data (e.g. accounts that represent businesses, animals, musicians, etc.), especially because Twitter doesn’t currently separate these accounts out from “real” human individuals in the ways that Facebook and Instagram do.
Regardless of the cause of these anomalies though, we advise caution when analysing or interpreting Twitter’s reported figures for use by gender.
Twitter user growth in the Republic of Korea
Data published in Twitter’s own ad planning tools show that Twitter’s potential ad reach in the Republic of Korea increased by 2.6 million (+36.1 percent) between the start of 2022 and early 2023.
Meanwhile, the same data show that the number of users that marketers could reach with ads on Twitter in the Republic of Korea increased by 200 thousand (+2.1 percent) between October 2022 and January 2023.
However, please note that the figures published in Twitter’s planning tools appear to be liable to significant fluctuation – even over short periods of time – and these anomalies may impact the reliability and representativeness of this change data.

Mobile connections in South Korea in 2023
Data from GSMA Intelligence shows that there were 64.19 million cellular mobile connections in the Republic of Korea at the start of 2023.
However, note that many people around the world make use of more than one mobile connection – for example, they might have one connection for personal use, and another one for work – so it’s not unusual for mobile connection figures to significantly exceed figures for total population.
GSMA Intelligence’s numbers indicate that mobile connections in South Korea were equivalent to 123.9 percent of the total population in January 2023.
The number of mobile connections in the Republic of Korea increased by 1.4 million (+2.3 percent) between 2022 and 2023.
