The Ulch are an indigenous people of the Russian Far East who speak a Tungusic language known as Ulch. Over 90% of Ulchis live in Ulchsky District of Khabarovsk Krai, Russia. According to the 2002 Census, there were 2,913 Ulchs living in Russia — down from 3,173 recorded in the 1989 Census, but up from 2,494 recorded in the 1979 Census, and 2,410 recorded in the 1970 Census. According to the 2010 Census there were 2,765 Ulchs in Russia. In terms of cultural anthropology, the Ulch do not constitute a homogeneous group. They are sometimes considered grouped with other so-called "Paleosiberian" peoples, also known as the "Amur-Sakhalin group". According to Sukernik et al., the mitochondrial DNA of the present-day Ulchi population belongs predominantly to haplogroup Y1a, which is shared with Nivkhs, Koryaks, Evens, and Mongolians and is estimated to have a time to most recent common ancestor of approximately 6,000 years before present on the basis of complete genomes or approximately 1,800 years before present on the basis of synonymous positions. Another 20% of the present-day Ulchi population belongs to mitochondrial DNA haplogroup D, which is significantly more diverse than their haplogroup Y1a mtDNA and can be resolved as follows: 12/160 = 7.5% D4o2, 4/160 = 2.5% D4h, 3/160 = 1.9% D4e4, 3/160 = 1.9% D4j, 2/160 = 1.25% D3, 2/160 = 1.25% D4c2, 1/160 = 0.6% D4a1, 1/160 = 0.6% D4b2b, 1/160 = 0.6% D4g2b, 1/160 = 0.6% D4m2, 1/160 = 0.6% D4o1, 1/160 = 0.6% D5a. Haplogroups C and G are also well represented. The remainder of the Ulchi mitochondrial DNA pool consists of haplogroups N9b, M8a, F1a, M7, M9a1, Z1, and B5b2. According to a study by Balanovska et al., present-day Ulchi malesbelong to Y-DNA haplogroupsC-M217, C-M48, 4/52 = 7.7% C-F13686, 1/52 = 1.9% C-B470, and 4/52 = 7.7% C-B93, the last of which is a deeply divergent branch belonging to C-M48), O-M175, Q-M242, N-M231, I-P37, and J–M267. The population genetics of the Ulchi are linked to 7,700 year old remains from Chertovy Vorota Cave and are also genetically similar to an East Asian genetic component within Native Americans. The Ulchi do not appear to have originally possessed the "Ancient North Eurasian" genetic component found in Native American, Central Asian, South Asian, and West Eurasian populations; the Ulchi are also genetically distinct from the more numerous East Siberian groups in modern times, such as Mongolian and Turkic peoples. ca. 1854-1860A genetic analysis in 2016 showed that the Ulchi are related or at least influenced by the Ainu and their ancestors the Jōmon people. According to the study, the Ainu-like genetic contribution in the Ulch people is about 17,8% or 13,5%.
