Origin
The surname "KIM" is of Korean origin and has a long history dating back to the 7th century AD during the Silla Kingdom on the Korean peninsula. It is derived from the Old Korean word "gim" or "kim", meaning "gold" or "iron".
In ancient times, the name was often associated with nobility or high social status, as possessions of gold and iron were symbols of wealth and power. The earliest recorded examples of the name can be found in the Samguk Sagi, a historical record of the Three Kingdoms period in Korea, which mentions individuals with the surname Kim.
During the Goryeo Dynasty (918-1392 AD), the Kim clan became one of the most prominent and influential families in Korea. Many members of the Kim family held high positions in the royal court and made significant contributions to the development of Korean culture and society.
One notable figure from this period was Kim Bu-sik (1075-1151 AD), a renowned historian and scholar who authored the Samguk Sagi, a comprehensive history of the Three Kingdoms period. Another prominent individual was Kim Gongyang (1516-1600 AD), a celebrated Confucian scholar and philosopher during the Joseon Dynasty.
In the 19th century, the Kim family played a crucial role in the Donghak Peasant Revolution, a influential peasant uprising against the ruling Joseon Dynasty. One of the leaders of the revolution was Kim Inhu (1826-1906), a Donghak leader and religious reformer.
During the 20th century, several individuals with the surname Kim made significant contributions to Korean history and culture. Kim Gu (1876-1949) was a prominent independence activist and the final President of the Provisional Government of the Republic of Korea during the Japanese occupation. Kim Dae-jung (1924-2009), a former President of South Korea, was awarded the Nobel Peace Prize in 2000 for his efforts to promote democracy and human rights in South Korea.
Throughout its long history, the surname Kim has been closely associated with Korea's cultural, political, and intellectual heritage, reflecting the enduring influence and significance of this ancient family name.
Demographics
Among Census respondents with the surname Kim, the largest self-reported group is Asian/Pacific Islander at 93.8%. The next largest groups are White (2.5%) and Two or More Races (2.5%).
The bar chart below shows how Kim bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Kim surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
