A focused population profile of Thai people, their mainland Southeast Asian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Thai people are the majority population of Thailand, with historical roots across central Thailand and wider Tai-speaking movements in mainland Southeast Asia. Thailand also includes many regional and minority populations, including Isan, northern Thai, southern Thai, Mon, Khmer, Malay, Karen, Hmong, and others.
Thai is a Tai-Kadai language and the national language of Thailand. It has regional varieties and long historical contact with Khmer, Mon, Lao, Malay, Chinese, and other languages.
As a genetic reference, Thai should be read in a mainland Southeast Asian context. The closest matches help show how Thai relates to Mon, Khmer, Moken, Cambodian, Malay, Nyah Kur, and neighboring Southeast Asian references.
In the World Genetics modern G25 comparison, the closest non-self match for Thai is Moken. Other nearby references include Mon Thailand, Cambodian, Khmer Cambodia, and Malay Malaysia. This gives the Thai profile its nearest modern genetic context inside the current reference database.

The ancestry model gives deeper component proportions, while the closest-match table shows modern similarity. Thai results are best interpreted through mainland Southeast Asian population history, with Mon, Khmer, Tai, Malay, and other regional references nearby.
The heatmap should emphasize Thailand, Cambodia, mainland Southeast Asia, the Malay Peninsula, and neighboring Tai or Mon-Khmer reference zones.
The closest non-self match in this World Genetics comparison is Moken. Other nearby references include Mon Thailand, Cambodian, Khmer Cambodia, and Malay Malaysia.
In the current modern G25 reference set, Moken is the closest listed match to the Thai average after removing Thai itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Thai G25 average, giving the closest-match results a geographic view.
