Javanese DNA
Genetic origins and closest populations · Indonesia · Southeast Asia
Java is the most populous island in the world, and the Javanese are Indonesia's largest people. Its Hindu and Buddhist kingdoms built Borobudur and Prambanan in the 9th century, and Majapahit became a great maritime power in the 14th. Javanese is an Austronesian language, yet in our model the Javanese average is 87.5% Southeast Asian Neolithic farmer and only 12.5% Southern Chinese Neolithic, the component that tracks the Austronesian expansion from Taiwan. Genetic studies of western Indonesia explain this with an early layer of ancestry related to mainland Southeast Asian farmers, often linked with Austroasiatic speakers, which reached the islands before or alongside Austronesian speakers. That is why the closest modern averages, after an Indonesian sample from Jakarta (0.0071) and the Sundanese (0.0089), include the Kuy of Thailand and the Khmer of Cambodia. The closest ancient groups are Late Neolithic to Bronze Age Tam Pa Ping in Laos (0.0378) and Late Neolithic Gua Cha in Malaysia (0.0413).

Javanese is one of the 335 modern populations in our population genetics atlas. The numbers on this page describe the average Global25 (G25) genome of the Javanese individuals sampled in Indonesia. Like every population average, it smooths over a lot of variation between individuals.
Ancient make-up of the Javanese average
Modelled as a mix of deep ancestral reference populations, the Javanese average comes out as 87.5% Southeast Asian Neolithic farmers and 12.5% Southern Chinese Neolithic farmers. The Southeast Asian Neolithic farmers component reflects the Neolithic farmers of mainland Southeast Asia. With well over half of the total, this single source dominates the profile.
The fit is loose (fit distance 0.042), which usually means that none of the available reference populations is a close stand-in for part of this ancestry, so read the percentages as rough. This population was modelled with a global set of reference populations (ancient genomes, plus modern stand-ins where no suitable ancient genome exists), because West Eurasian sources alone cannot describe it.

Closest modern populations to Javanese
Genetically, the Javanese average sits nearest to Indonesian (Jakarta, Java/Bali Profile) at 0.007, Sundanese at 0.009 and Balinese at 0.019. On our scale, a distance of 0.007 counts as very close. By the tenth closest (Malay (Singapore)) the distance grows to 0.043, a common pattern for a population that shares ancestry with its neighbours while keeping a profile of its own.
| # | Population | Distance | Closeness |
|---|---|---|---|
| 1 | Indonesian (Jakarta, Java/Bali Profile) | 0.0071 | Very close |
| 2 | Sundanese | 0.0089 | Very close |
| 3 | Balinese | 0.0188 | Very close |
| 4 | Kuy (Thailand) | 0.0322 | Close |
| 5 | Khmer (Cambodian) | 0.0356 | Close |

| 8 | Ma'anyan | 0.0412 | Close |
| 9 | Temuan | 0.0415 | Close |
| 10 | Malay (Singapore) | 0.0428 | Close |
Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.
Closest ancient populations to Javanese
Looking back in time, the ancient sample that most resembles the Javanese average is Laos LNBA Tam Pa Ping (Late Neolithic to Bronze Age), at 0.038. India Uttarakhand Late Modern Roopkund (Southeast Asian Profile) and Malaysia LN Gua Cha come next. That is a close match: much of the modern profile was already present then, while later movements of people added further layers. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from Indonesia
Our ancient DNA database holds 30 individuals excavated in present-day Indonesia, dated from about 5,300 BC to 1751 AD. The most frequent Y-DNA haplogroups among them are O2a (3), C1b (1) and M1a (1), and the most frequent mtDNA haplogroups are B4 (4), Q1 (3) and E1 (2). These are people who lived on the same land in the past, not necessarily ancestors of today's Javanese population.

About these numbers
Keep in mind that a population average is a statistical summary of a limited number of sampled individuals. Real people inside any group vary, some carry more of one ancestry and some less, and no genetic profile decides who is or is not Javanese. Use these numbers as a map of deep ancestry, not as a label.
Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.

Frequently asked questions
What is the ancient genetic make-up of Javanese?
Modelled with deep ancestral reference populations, the Javanese average is about 87.5% Southeast Asian Neolithic farmers and 12.5% Southern Chinese Neolithic farmers. These proportions are model estimates for a group average, not exact values for any one person.
Which populations are genetically closest to Javanese?
In the G25 data, the closest modern populations to the Javanese average are Indonesian (Jakarta, Java/Bali Profile), Sundanese and Balinese. The closest ancient matches are Laos LNBA Tam Pa Ping, India Uttarakhand Late Modern Roopkund (Southeast Asian Profile) and Malaysia LN Gua Cha.
Can a DNA test tell me if I am Javanese?
No DNA test can confirm an ethnicity or a nationality. What DNA can show is how similar your genome is to the sampled Javanese average and to its neighbours. If you have G25 coordinates, paste them in the comparison box on this page to check that for free.
Which ExploreYourDNA report suits Javanese ancestry?
For the Javanese average, the regional report to choose is Lapita – Austronesian & Pacific Report, which our fit test rates as an excellent match. Your own DNA may differ from the average, so the free Report Finder checks every report against your file before you buy.
Where does the data on this page come from?
From the averaged Global25 (G25) coordinates of the sampled individuals: genetic distances to other modern and ancient population averages, and a non-negative least-squares model against deep ancestral reference populations.
