A focused population profile of Saudi Arabs, their Arabian Peninsula background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Saudi Arabs are the Arabic-speaking population of Saudi Arabia, the largest country on the Arabian Peninsula. The country includes several major historical regions, including Najd in the center, Hejaz along the Red Sea, the Eastern Province on the Gulf, Asir and Jizan in the southwest, and northern desert regions connected with wider Bedouin and tribal networks.
Arabic is the national language, but everyday speech varies by region. Najdi Arabic is associated with central Saudi Arabia, Hejazi Arabic with western cities such as Jeddah, Mecca, and Medina, Gulf Arabic with eastern Arabia, and southern varieties with the southwest.
Because Saudi Arabia covers much of the Arabian Peninsula, Saudi Arab genetic results can include both a broad Arabian average and more region-specific profiles such as Najd, Hejaz, Jizan, or eastern Saudi groups.
In the World Genetics modern G25 comparison, the closest non-self match for Saudi Arab is Emirati Arab (Arabian Profile). Other nearby references include Saudi Arab Najd, Yemenite Jew, Yemeni Arab Al Jawf, and Bedouin Negev. This gives the Saudi Arab profile its nearest modern genetic context inside the current reference database.

The ancestral breakdown models deeper layers of ancestry and should be read together with the closest-match table. For Saudi Arabs, the modern comparison is the clearest guide: the overall pattern is Arabian Peninsula-centered, with regional shifts toward the Gulf, Hejaz, Yemen, or Mesopotamia depending on the reference.
The heatmap should concentrate across the Arabian Peninsula, especially central and eastern Arabia, while also showing affinity to neighboring Gulf and Yemeni references.
The closest non-self match in this World Genetics comparison is Emirati Arab (Arabian Profile). Other nearby references include Saudi Arab Najd, Yemenite Jew, Yemeni Arab Al Jawf, and Bedouin Negev.
In the current modern G25 reference set, Emirati Arab (Arabian Profile) is the closest listed match to the Saudi Arab average after removing Saudi Arab itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Saudi Arab G25 average, giving the closest-match results a geographic view.
