Koreans

South Koreans refer to themselves as Hanguk-in or Hanguk-saram, both of which mean "people of the Han". The "Han" in the names of the Korean Empire, Daehan Jeguk, and the Republic of Korea (South Korea), Daehan Minguk or Hanguk, are named in reference to the Three Kingdoms of Korea, not the ancient confederacies in the southern Korean Peninsula. Members of the Korean diaspora often use the term Han-in. North Koreans refer to themselves as Joseon-in or Joseon-saram, both of which literally mean "people of Joseon". The term is derived from Joseon, the last dynastic kingdom of Korea. Similarly, Koreans in China refer to themselves as Chaoxianzu in Chinese or Joseonjok, Joseonsaram in Korean, which are cognates that literally mean "Joseon ethnic group". Koreans in Japan refer to themselves as in Japanese or Jaeil Joseonin, Joseonsaram, Joseonin in Korean. Ethnic Koreans living in Russia and Central Asia refer to themselves as Koryo-saram, alluding to Goryeo, a Korean dynasty spanning from 918 to 1392, which also spawned the word 'Korea'. In the chorus of the South Korean national anthem, Koreans are referred to as Daehan-saram ("people of the great han"). In an inter-Korean context, such as when dealing with the Koreanic languages or the Korean ethnicity as a whole, South Koreans use the term . ==Origins==

The origin of Koreans has not been well clarified yet. Based on linguistic, archaeologic and genetic evidence, their place of origin is located somewhere in Northeast Asia, but its exact pattern of expansion and arrival into the Korean peninsula remain unclear. Koreans were suggested to have originated from a similar source as Central Asian Mongolians from a genetic perspective. Archaeological evidence suggests that Proto-Koreans were migrants from Manchuria during the Bronze Age. The origins of the Korean language and people are subjects of ongoing debate. Some theories suggest connections to the Altaic region, proposing links with languages and populations in Northern Asia, including Mongolic, Turkic, and Tungusic groups. However, these claims remain inconclusive, and many scholars argue that Korean belongs to its own distinct Koreanic family, with unique linguistic and cultural origins. Scholars suggest that Koreanic speakers came from Northeast Asia and migrated southwards to the Korean Peninsula, where they replaced or assimilated the local Japonic speakers. Whitman (2011) suggests that the Proto-Koreans arrived in the southern part of the Korean Peninsula at around 300 BCE and coexisted with the descendants of the Japonic Mumun cultivators (or assimilated them). Vovin suggests Proto-Korean is equivalent to the variant of Koreanic languages spoken in southern Manchuria and northern Korean Peninsula by the time of the Three Kingdoms of Korea period and spread to southern Korea through influence from Goguryeo migrants. The arrival of early Koreans can be associated with the Bronze Age dagger culture, which expanded from the West Liao River region. Archaeologic evidence points to a connection between the pottery-making style of the Late Neolithic to Bronze Age cultures in the West Liao River basin and the Korean Peninsula. Miyamoto 2021 similarly argues that Proto-Koreanic arrived with the "rolled rim vessel culture" (Jeomtodae culture) from the Liaodong Peninsula, gradually replacing the Japonic speakers of the Mumun-Yayoi culture. However, some scholars reject the notion that the Korean speakers were not native to the Korean Peninsula, and argue that no solid evidence of such linguistic migration/shift as well as population and material change in the peninsular region has ever been found to support later migrations. These farmers can be modeled as having Ancient Northern East Asian ancestry, related to Yellow River farmers from the Middle to Late Neolithic period, and Ancient Northeast Asian ancestry, related to Amur hunter-gatherers. West Liao River ancestry is associated with the Upper Xiajiadian culture, which can represent the ancestral source for Bronze Age and modern Koreans. According to Kim et al. (2020), most genetic variation within modern Koreans is attributed to the introduction of combined Vat Komnou and Nui Nap ancestries from Southern China after the Bronze Age. Other studies also show this Southeast Asian contribution in proto-Koreans. Wang and Wang (2022) states that Koreans from the Neolithic to the Three Kingdoms Period, a span covering roughly 6000 BC to AD 500, have Jōmon ancestry, which ranged from 10% to 95%, and significantly contributed to the genetic makeup of modern Koreans. But subsequent arrivals of newcomers from Manchuria 'diluted' this Jōmon ancestry and made the Koreans genetically homogenous. Because of this, Koreans are closely related to Korea TK_1 individuals, who additionally exhibit affinities with Eastern Chinese, due to their lower Jōmon ancestry. Jōmon ancestry in modern Koreans is estimated to be about 5%. Koreans also have close affinities with the Doigahama Yayoi individual, who are closely related to ancient (e.g. Yayoi, Kofun etc.) and modern Japanese populations,and Yellow River populations from the Late Bronze Age and Iron Age. Some regional variance may exist; in a study of South Korean Y-DNA published in 2011, the ratio of O2-M122 to O1b2-M176 is greatest in Seoul-Gyeonggi (1.8065), with the ratio declining in a counterclockwise direction around South Korea (Chungcheong 1.6364, Jeolla 1.3929, Jeju 1.3571, Gyeongsang 1.2400, Gangwon 0.9600). Haplogroup C2-M217 tends to be found in about 13% of males from most regions of South Korea, but it is somewhat more common (about 17%) among males from the Gyeongsang region in the southeast of the peninsula and somewhat less common (about 7%) among males from Jeju, located off the southwest coast of the peninsula. Haplogroup C2-M217 has been found in a greater proportion (about 26%) of a small sample (n=19) of males from North Korea. Koreans have also been identified as belonging to the C2b1a1 sublineage specifically, indicating shared ancestry with Han and Mongolic-speaking populations on the paternal line. However, haplogroups are not a reliable indicator of an individual's overall ancestry; Koreans are more similar to one another in regard to their autosomes than they are similar to members of other ethnic groups. Studies of polymorphisms in the human Y-chromosome have so far produced evidence to suggest that the Korean people have a long history as a distinct, mostly endogamous ethnic group, with successive prehistoric waves of people moving to the peninsula and two major Y-chromosome haplogroups. The mitochondrial DNA markers (mtDNA haplogroups and HVR-I sequences) of Korean populations showed close relationships with Manchurians, Japanese, Mongolians and Northern Chinese but not with Southeast Asians. Y-chromosomal distances showed a close relationship to most East Asian population groups, including Southeast Asian ones. Koreans share a close genetic relationship with Yamato Japanese and Manchu populations, as well as other Tungusic-speaking groups, reflecting shared ancestry and historical interactions. Additionally, they exhibit genetic affinity with Northern Han Chinese populations, though to a lesser degree compared to Manchu and Japanese populations. These relationships are supported by genome-wide analyses highlighting the complex genetic structure of East Asian populations. The study "Genomic insights into the formation of human populations in East Asia" states that Koreans are genetically closest to Yamato Japanese based on FST genetic distance measurements. The research highlights the complex genetic structure of East Asian populations, shaped by historical migrations and admixture events. The reference population for Koreans used in Geno 2.0 Next Generation is 94% Eastern Asia and 5% Southeast Asia & Oceania. Genealogy Korea Foundation Associate Professor of History, Eugene Y. Park said that many Koreans seem to have a genealogical memory blackout before the twentieth century. According to him the vast majority of Koreans do not know their actual genealogical history. Through "inventing tradition" in the seventeenth and eighteenth centuries, families devised a kind of master narrative story that purports to explain a surname-ancestral seat combination's history to the extent where it is next to impossible to look beyond these master narrative stories. He gave an example of what "inventing tradition" was like from his own family's genealogy where a document from 1873 recorded three children in a particular family and a later 1920 document recorded an extra son in that same family. Park said that these master narratives connect the same surname and ancestral seat to a single, common ancestor. This trend became universal in the nineteenth century, but genealogies which were published in the seventeenth century actually admit that they did not know how the different lines of the same surname or ancestral seat are related at all. Only a small percentage of Koreans had surnames and ancestral seats to begin with, and that the rest of the Korean population had adopted these surname and ancestral seat identities within the last two to three hundred years. ==Culture==

North Korea and South Korea share a common heritage, but the political division since 1945 has resulted in some divergence of their modern cultures. ==Language==

The language of the Korean people is the Korean language, which uses Hangul, invented by Sejong the Great, as its main writing system. Daily usage of Hanja has been phased out in Korean peninsula other than usage by some South Korean newspapers and media companies when referring to key politicians (e.g. current and former Presidents, leaders of major political parties) or handful of countries (e.g. China, Japan, Canada, United States, United Kingdom) as an abbreviation. Otherwise, Hanja is exclusively used for academic, historical and religious purposes. Roman alphabet is the de facto secondary writing system in South Korea especially for loan words and is widely used in day-to-day and official communication. There are more than 78 million speakers of the Korean language worldwide. ==Demographics==

Large-scale emigration from Korea began as early as the mid-1860s, mainly into the Russian Far East and Northeast China (also historically known by the exonym Manchuria); these populations would later grow to more than two million Koreans in China and several hundred thousand Koryo-saram (ethnic Koreans in Central Asia and the former USSR). During the Korea under Japanese rule of 1910–1945, Koreans were often recruited and or forced into labour service to work in mainland Japan, Karafuto Prefecture (Sakhalin), and Manchukuo; the ones who chose to remain in Japan at the end of the war became known as Zainichi Koreans, while the roughly 40,000 Koreans who were trapped in Karafuto after the Soviet invasion are typically referred to as Sakhalin Koreans. South Korea , Galicia, (Spain). In June 2012, South Korea's population reached 50 million and by the end of 2016, South Korea's population has surpassed 51 million people. Since the 2000s, South Korea has been struggling with a low birthrate, leading some researchers to suggest that if current population trends hold, the country's population will shrink to approximately 38 million population towards the end of the 21st century. In 2018, fertility in South Korea became again a topic of international debate after only 26,500 babies were born in October and an estimated of 325,000 babies in the year, causing the country to have the lowest birth rate in the world. North Korea Estimating the size, growth rate, sex ratio, and age structure of North Korea's population has been extremely difficult. Until release of official data in 1989, the 1963 edition of the North Korea Central Yearbook was the last official publication to disclose population figures. After 1963 demographers used varying methods to estimate the population. They either totalled the number of delegates elected to the Supreme People's Assembly (each delegate representing 50,000 people before 1962 and 30,000 people afterwards) or relied on official statements that a certain number of persons, or percentage of the population, was engaged in a particular activity. Thus, on the basis of remarks made by President Kim Il Sung in 1977 concerning school attendance, the population that year was calculated at 17.2 million persons. During the 1980s, health statistics, including life expectancy and causes of mortality, were gradually made available to the outside world. In 1989, the Central Bureau of Statistics released demographic data to the United Nations Population Fund in order to secure the UNFPA's assistance in holding North Korea's first nationwide census since the establishment of the state in 1948. Although the figures given to the United Nations might have been distorted, it appears that in line with other attempts to open itself to the outside world, the North Korean regime has also opened somewhat in the demographic realm. Although the country lacks trained demographers, accurate data on household registration, migration, and births and deaths are available to North Korean authorities. According to the United States scholar Nicholas Eberstadt and demographer Brian Ko, vital statistics and personal information on residents are kept by agencies on the ri ("village", the local administrative unit) level in rural areas and the dong ("district" or "block") level in urban areas. The Greater Los Angeles Area and New York metropolitan area in the United States contain the largest populations of ethnic Koreans outside of Korea or China. The Korean population in the United States represents a small share of the American economy, but has a disproportionately positive impact. Korean Americans have a savings rate double that of the U.S. average and also graduate from college at a rate double that of the U.S. average, providing highly skilled and educated professionals to the American workforce. According to the U.S. Census Bureau's Census 2021 data, median household earnings for Korean Americans was $82,946, approximately 19.0% higher than the U.S. average at the time of $69,717. Significant Overseas Korean populations are also present in China, Japan, Argentina, Brazil, and Canada as well. The number of Koreans in Indonesia grew during the 1980s, while during the 1990s and 2000s the number of Koreans in the Philippines and Koreans in Vietnam have also grown significantly. In Central Asia, significant populations reside in Uzbekistan and Kazakhstan, as well as parts of Russia including the Far East. Known as Koryo-saram, many of these are descendants of Koreans who were forcely deported during the Soviet Union's Stalin regime. The Korean overseas community of Uzbekistan is the 5th largest outside Korea. Pak Cheil estimated there to be 70,000 to 80,000 "semi-Koreans" in Japan in the years immediately after the war. Many of them remained in Japan as Zainichi Koreans, maintaining their Korean heritage. However, due to assimilation, their numbers are much lower in recent times. Kopinos are people of mixed Filipino and Korean descent. The 'Mixed Filipino Heritage Act of 2020' estimated there were around 30,000 Kopinos. Lai Đại Hàn is a Vietnamese term referring to mixed children born to South Korean men and South Vietnamese women during the Vietnam War. These children were largely conceived as the result of wartime rape. No exact data is available on the number of Korean-Vietnamese because many of them choose to conceal their roots, but an estimate by a Korean scholar says the number of Lai Dai Han around the world is at least 5,000 to as many as 150,000. ==See also==
