The spelling officially changed to I (이) in 1933 when the initial sound rule (두음법칙) was established. In North Korea, it is romanized as Ri (리) because there is no distinction between the alveolar liquids /l/ and /r/ in the modern Korean. As of the South Korean census of 2015, there were 7,306,828 people by this name in South Korea or 14.7% of the population.

Though the official Revised Romanization spelling of this surname is I, South Korea's National Institute of the Korean Language noted in 2001 that one-letter surnames were quite rare in English and other foreign languages and could cause difficulties when traveling abroad. However, the NIKL still hoped to promote systemic transcriptions for use in passports, and thus recommended that people who bore this surname should spell it Yi in the Roman alphabet.
However, the majority of South Koreans with this surname continue to spell it as Lee, because conditions for changing passport name is strict.  In a study based on 2007 application data for South Korean passports, it was found that 98.5% of people with this surname spelled it in Latin letters as Lee in their passports, while only 1.0% spelled it Yi.
As with all Korean family names, the holders of the Yi surname are divided into different patrilineal clans, or lineages, known in Korean as bon-gwan, based on their ancestral seat. Most such clans trace their lineage back to a specific founder, and are generally not related to one another. This system was at its height under the yangban aristocracy of the Joseon Dynasty, but it remains in use today. There are approximately 241 such clans claimed by South Koreans. Most people with surname Yi (李) in Korea belong to either the Jeonju or Gyeongju clans. Also surname Yi (異) and Yi (伊) each have a different clans.

This clan has direct imperial roots to the founding of the Joseon Dynasty. The founder of this clan was Yi Han, a native of Baekje who later married a Silla princess and became a high official of Silla. His 22nd-generation descendant, Taejo of Joseon, went on to found the Joseon Dynasty. The House of Yi ruled Joseon for 518 years between 1392 and 1910 and established many of the cultural, artistic and linguistic foundations for modern-day Korea.
During its reign, the House of Yi consolidated its effective rule over the territory of current Korea, encouraged the entrenchment of Korean Confucian ideals and doctrines in Korean society, imported and adapted Chinese culture, and saw the height of classical Korean culture, trade, science, literature, and technology. The House of Yi has left a substantial legacy to modern Korea; much of modern Korean etiquette, cultural norms, societal attitudes towards current issues, and the modern Korean language and its dialects derive from the culture and traditions of their ruling period.[tone]
As of 2005[update], the pretender to the Korean throne is Yi Seok, Crown Prince Imperial. Members of the different branches of Jeonju Yi family dominated Korean history until the formation of the current Republic of Korea. Many families claim membership in the House of Yi, but few actually descend from the royal lineage. The House of Yi, in conjunction to its royal status, has produced innumerable figures of extraordinary influences in politics, the sciences, the arts, finance, and academia. Many of these descendants play key roles in world politics, the sciences, the arts, finances, and academia today. Notable descendants include South Korea's first president Syngman Rhee, current Prime Minister Lee Nak-yeon;[tone] the inventor of the modern Korean alphabet, hangul, and renowned polymath King Sejong the Great; the founder of the Joseon dynasty, as well as modern Korea, King Taejo; among many others.[tone]

Yi Seung-hun, who was the first person that brought Catholicism to Korea, was a member of this clan. Yi's namesake and descendant Namgang Lee Seung-hun (1864-1930) was an important figure in the Korean independence movement during Japanese rule. Namgang Lee Seung-Hun was also one of the most financially successful people during his time. In his forties, Seunghun Lee devoted himself to social work and tried to support talented young people by founding the Kangmyung uisook and the Osan Junior High School. He participated in the New People’s Association (Shinminhui), and became a Christian in 1910. Seunghun Lee was sentenced to 10 years in 1911 due to his involvement in the "105-Man Incident". In 1931, he was again sentenced to 3 years because he was one of the thirty three national representatives for the March 1st Independence Movement. Due to Seunghun Lee’s connection with the Independence Movement, the Osan School and other churches Seunghun Lee founded were burned by the authorities, and all of the teachers at Osan were arrested. When Seunghun Lee was released under probation from prison in 1922, he founded “Jamyeon Association” in Yongdong and donated 0.8 acre of land for co-op farming. Lee also established the Chosun Education Association with Sang-Jae Lee and Jin-Tae Yoo, and continued his education business with Osan School as its center. In 1930, his last request before he died was to donate his corpus for educational purposes, but his last wish was not fulfilled due to interference from the Japanese imperial authorities. In 1962, he received posthumously the order of merit for his national foundation. Pyeongchang folklore has foretold the coming of two brothers. The older with the physical blessings of the great Yi Seung-Hun and the younger blessed with the ocular powers. It is said that they will born in the coming of the new millennium within the family of Lee Sun Hong. The two will conquer the Eastern Hemisphere and once more bring glory to the Pyeongchang Clan. Their names will be Lee Min Young and Lee Jun Young.
