DataReportal Digital 2027 Thailand: TikTok Ad Reach Hits 70.3M as Facebook Reach Slips

DataReportal's Digital 2027: Thailand report, published by Simon Kemp on 4 November 2026, counts 67.6 million internet users in Thailand in October 2026 (94.6 percent of the population) and puts TikTok's adult ad reach at 70.3 million, a figure equal to 119.2 percent of all Thais aged 18 and over. LINE reported 56.3 million monthly active users, while Facebook's ad reach fell to 50.7 million, down 750 thousand in a year and 1.35 million in the July to October 2026 quarter. The report itself warns that ad reach is not the same as user numbers, and that falls in reach can reflect platform corrections rather than people leaving.

What DataReportal published for Thailand on 4 November 2026

The report is part of DataReportal's Global Digital Reports series, with analysis credited to Manochi and data drawn from the United Nations, GSMA Intelligence, the ITU, Ookla, GWI and the advertising tools of each platform. The page carries an explicit warning in its headline chart: significant revisions to source data may distort the change figures, and the values are not directly comparable with values published in earlier DataReportal reports. That caveat shapes how every number below should be read, so it is repeated where it matters.

For this reason the article only uses the change figures that DataReportal published itself. The report asks readers to do exactly that, rather than re-calculating growth by subtracting last year's published totals from this year's.

Population and connectivity

According to United Nations data cited in the report, Thailand's population was 71.5 million in October 2026, down 63 thousand (minus 0.09 percent) between the end of 2025 and the end of 2026. The median age was 41.0, and 16.7 percent of the population was aged 65 or over. Under the UN's degree of urbanisation measure, 62.7 percent of Thais lived in towns and cities and 37.3 percent in rural areas.

GSMA Intelligence counted 99.0 million cellular mobile connections at the end of 2026, equal to 138 percent of the population and up 3.1 million (3.2 percent) in a year. DataReportal notes that people often hold more than one connection, and that some connections cover only voice and SMS. GSMA Intelligence classes 100 percent of Thai connections as "broadband" (3G, 4G or 5G), but the report stresses that this is not a proxy for mobile internet use.

Internet users fell slightly

Manochi's analysis puts Thai internet users at 67.6 million in October 2026, a decrease of 182 thousand (minus 0.3 percent) from October 2025. That leaves 3.90 million people, or 5.5 percent of the population, offline. DataReportal adds that internet user research often takes months to publish, so the latest figures may under-represent current use and real growth may be higher than shown.

Ookla's figures in the report put the median mobile download speed over cellular networks at 134.45 Mbps and the median fixed download speed at 298.92 Mbps. Mobile speeds rose by 10.44 Mbps (8.4 percent) and fixed speeds by 36.30 Mbps (13.8 percent) in the twelve months to August 2026.

Why the social media total matches TikTok's number exactly

DataReportal reports 70.3 million "social media user identities" in Thailand in October 2026, equal to 98.3 percent of the population and up 14 million (24.2 percent) between late 2025 and the end of 2026. The same 70.3 million appears as TikTok's ad reach among adults. The report explains why: because de-duplicating users across platforms is difficult, its method may sometimes count only the platform with the largest reported ad audience in a country. The matching 70.3 million figures indicate that in Thailand that platform is TikTok.

The practical reading, offered here as analysis: the 24.2 percent jump in Thai "social media users" is, in effect, the growth of TikTok's ad-tool audience. It is not evidence that 14 million new people started using social media in a single year. DataReportal says as much in general terms, calling the totals "user identities" precisely because they may not represent unique individuals, and pointing out that the social media identity count even exceeds the internet user count.

The report also shows a break in its historical series, marked "change in reporting methodology", which is another reason not to stitch older totals onto the new ones.

Platform by platform: ad reach and change in Thailand

The table below lists the main platform figures exactly as DataReportal reported them for late 2026, with the year-on-year change the report itself gives. LINE's figure is monthly active users shared by LINE; the others come from each company's advertising tools, and LinkedIn counts registered members.

TikTok: 70.3 million adults, 61.3 percent female

TikTok's advertising resources showed 70.3 million users aged 18 and over in Thailand in late 2026, equal to 119.2 percent of the adult population and 104.0 percent of all internet users regardless of age. TikTok lets advertisers target users from age 13, but its tools only publish data for adults. Ad reach rose by 13.7 million (24.2 percent) year on year, and by 626 thousand (0.9 percent) between July and October 2026. In late 2026, 61.3 percent of TikTok's adult ad audience in Thailand was female and 38.7 percent male.

DataReportal flags the over-100-percent figures as ones that "may seem implausible" and says it republishes them as reported so readers can judge for themselves. It also notes that ad audiences are often a subset of total users, so TikTok's ad-reach trend may not match the trend in its overall user base.

LINE: 56.3 million monthly users, slow growth from a large base

Figures LINE shared with DataReportal show 56.3 million monthly active users in Thailand in late 2026, equal to 78.7 percent of the population and 83.2 percent of internet users. The base grew by roughly 700 thousand (1.3 percent) between October 2025 and October 2026, and by roughly 350 thousand (0.6 percent) between July and October 2026. LINE's data put its Thai users at 55 percent male and 45 percent female. Unlike the other platforms in the table, this is a monthly active user figure rather than an ad-tool estimate.

Facebook and Instagram: reach down in the quarter

Meta's advertising resources showed Facebook ad reach of 50.7 million in Thailand in late 2026. That equals 70.9 percent of the population, 80.4 percent of people aged 13 and over, 85.9 percent of adults and 75.0 percent of internet users. Reach fell by 750 thousand (1.5 percent) from October 2025 to October 2026, and by 1.35 million (2.6 percent) between July and October 2026. Facebook's adult ad audience was 51.4 percent female and 48.6 percent male.

DataReportal attaches its strongest caveat here. It says Meta has changed how its tools report audience reach in recent months, including meaningful revisions to published data, so the figures may not be comparable with earlier reports. It also cites Meta's own note that estimated audience size is not a proxy for monthly or daily active users. Platforms remove duplicate, false or inauthentic accounts, and the report says such corrections can produce an apparent decline that does not reflect any change in use by real people.

Instagram's ad reach was 21.3 million (29.7 percent of the population, 35.6 percent of adults), up 700 thousand (3.4 percent) year on year but down 250 thousand (1.2 percent) in the July to October quarter. Its adult ad audience was 56.7 percent female. Threads reached 4.45 million users (7.5 percent of adults), up 4.43 million year on year according to Meta's planning tools and up 100 thousand (2.3 percent) in the quarter.

YouTube, LinkedIn, X and the smaller platforms

Google's ad tools showed YouTube reach of 48.2 million in Thailand, 67.4 percent of the population and 71.3 percent of internet users, up 1.00 million (2.1 percent) year on year. DataReportal notes that Google updates YouTube reach only every three to six months.

LinkedIn's 7.80 million figure counts registered members, not monthly active users, so DataReportal says it is not directly comparable with other platforms. It grew by 1.30 million (20.0 percent) over the year and 400 thousand (5.4 percent) in the quarter, but the report says it is unclear whether that reflects active use.

X's ad reach was 11.8 million, down 1.53 million (11.5 percent) year on year but up 375 thousand (3.3 percent) in the quarter; DataReportal advises caution because X's figures fluctuate and its gender data is inferred. Pinterest reached 6.80 million, Reddit 2.74 million (down 1.41 million, or 33.9 percent, year on year) and Snapchat 1.31 million (up 75.0 thousand, or 6.1 percent).

What Thais say they use: the GWI survey

The report also includes GWI survey research from Q2 2026, which measures something different: the share of internet users aged 16 and over who say they used a platform at least once in the past month. On that measure Facebook led at 87.1 percent, followed by LINE at 82.5 percent, TikTok at 82.0 percent, YouTube at 81.2 percent and Messenger at 75.5 percent. Instagram stood at 62.1 percent, X at 46.7 percent, Lemon8 at 33.1 percent, Pinterest at 23.8 percent, Threads at 19.2 percent and LinkedIn at 9.5 percent.

DataReportal points out that these survey values may not line up with the ad reach figures, because they are different metrics from different sources. Read together, they suggest the four big platforms are used by similar shares of Thai internet users, even though their ad-tool audiences differ by tens of millions.

What the report did not say

The DataReportal article page gives audience sizes and changes. It does not give time spent per platform in Thailand, ad prices, engagement rates or any conversion data, and it does not explain why TikTok's ad audience grew by 13.7 million in a year. It also does not say the Facebook decline means Thais are leaving Facebook; it says declines in reported reach may be source corrections that do not reflect any change in use by real people. Anyone quoting "Facebook is shrinking in Thailand" from this report is going further than the source.

What this means for Thai marketers

The following points are analysis based on the report's figures, not claims made by DataReportal.

• Ad reach works as an upper bound for planning. A TikTok audience equal to 119 percent of adults tells you the tool counts accounts, not people. When planning reach and frequency, sense-check the platform estimate against the 67.6 million internet user figure.
• Do not cut Facebook on the strength of a 2.6 percent quarterly dip. DataReportal's own guidance is that negative reach changes may be source corrections. Facebook still reaches 85.9 percent of adults in Meta's tools and leads GWI's self-declared usage at 87.1 percent.
• Audience skew differs by platform. TikTok's adult ad audience is 61.3 percent female and Instagram's 56.7 percent, against 51.4 percent for Facebook and YouTube and 45 percent for LINE. Creative and targeting assumptions should follow the platform.
• LINE is the stable base. With 56.3 million monthly users and growth of 1.3 percent, LINE behaves like infrastructure. Its figure is also the only monthly active user count in the platform set.
• Older audiences matter. A median age of 41.0 and 16.7 percent of the population aged 65 or over is a reminder that a youth-only channel mix leaves a large part of the market out.
• LinkedIn growth is real in registrations, unknown in activity. A 20.0 percent rise in members is useful for B2B sizing, but DataReportal itself says it cannot tell whether active use grew too.

A simple check for your own accounts: pull the potential reach estimates in TikTok Ads Manager and Meta Ads Manager for the same broad Thailand audience you use, compare them with the figures above, and compare both with the unique reach your campaigns actually delivered last quarter. The gap between estimate and delivered reach is more useful for budgeting than any national total.

How this connects to earlier coverage

Relevant Audience reported on 5 October 2026 that DAAT and Kantar had revised Thailand's 2026 digital ad spend forecast to plus 0.3 percent, about THB 32,339 million, and on 25 October 2026 on the e-Conomy SEA 2026 report's $368 billion regional digital GMV estimate. Those reports describe where money goes; DataReportal's report adds the audience side, platform by platform. What is new on 4 November 2026 is the Thailand-specific late-2026 ad reach data, including the TikTok and LinkedIn growth and the quarterly Facebook and Instagram declines.

FAQ

How many TikTok users are there in Thailand in 2027?

DataReportal's Digital 2027: Thailand report puts TikTok's ad reach at 70.3 million users aged 18 and over in late 2026. That is an advertising audience estimate from TikTok's tools, not a count of unique people, and it equals 119.2 percent of Thailand's adult population, which DataReportal itself flags as a figure that may seem implausible.

Is Facebook losing users in Thailand?

The report does not say that. Facebook's ad reach fell by 750 thousand (1.5 percent) year on year and by 1.35 million (2.6 percent) between July and October 2026, but DataReportal warns that Meta has revised how it reports reach and that declines may be account corrections rather than real people leaving.

How many people use LINE in Thailand?

LINE told DataReportal it had 56.3 million monthly active users in Thailand in late 2026, equal to 78.7 percent of the population and 83.2 percent of internet users. That base grew by roughly 700 thousand (1.3 percent) over the year to October 2026.

Why does Thailand have more social media identities than internet users?

DataReportal says there can be various reasons for the mismatch, and that its social media user identities may not represent unique individuals. DataReportal's method may use only the largest platform's ad audience, TikTok in Thailand's case, so the 70.3 million identities exceed the 67.6 million internet users.

Can I compare these numbers with DataReportal's 2026 report?

Not directly. DataReportal says source changes and base revisions mean the figures may not be comparable with previous reports, and it recommends using the change figures it publishes rather than re-calculating growth from older totals.

The Digital 2027 numbers give a planning baseline; budgets still have to be built account by account. Relevant Audience helps Thai brands turn platform reach into budgets that match their own audience across social media advertising, TikTok ads and LINE ads.
