Origin
The surname Luk has its origins in England, tracing back to the 12th century. It is believed to be derived from the Old English word "luc," meaning "lock" or "enclosure." This suggests that the name may have originally referred to someone who lived near a gate or enclosed area.
One of the earliest recorded instances of the name can be found in the Pipe Rolls of Gloucestershire, dated 1195, which mention a person named Willelmus Luk. The Pipe Rolls were a series of financial records maintained by the English Exchequer, providing valuable insights into the names used during that period.
Another significant historical reference is the Hundred Rolls of 1273, which contained records of landholders and their holdings. These rolls include entries for individuals with the surname Luk, indicating their presence in various counties across England.
During the 13th century, the name Luk appeared in various spellings, such as Loke, Looke, and Lok, reflecting the fluidity of surname spellings in that era. These variations were often influenced by regional dialects and the preferences of scribes who recorded the names.
One notable bearer of the Luk surname was John Luk, a prominent merchant from Bristol who lived in the late 14th century. Records show that he was involved in trade with the continent and played a role in the city's economic affairs.
In the 16th century, the Luk surname was associated with several place names in England, such as Lukesland in Kent and Lukeshall in Essex. These toponymic references suggest that some families with the surname may have derived their name from the location where they resided.
Another individual of historical significance was Sir William Luk, who lived in the late 16th and early 17th centuries. He was a respected statesman and served as a Member of Parliament for Nottinghamshire in the early 1600s.
During the English Civil War in the mid-17th century, Captain Richard Luk was a notable figure who fought for the Parliamentarian forces. He was known for his bravery and military prowess in several key battles.
In the realm of literature, one cannot overlook the contribution of Samuel Luk, an English poet and playwright who lived from 1638 to 1719. His works, though not widely acclaimed during his lifetime, have since gained recognition for their lyrical quality and insightful commentary on contemporary society.
As the centuries progressed, the Luk surname continued to be found across various regions of England, with families often maintaining close ties to their ancestral homes and local communities.
Demographics
Among Census respondents with the surname Luk, the largest self-reported group is Asian/Pacific Islander at 89.2%. The next largest groups are White (4.6%) and Two or More Races (3.2%).
The bar chart below shows how Luk 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 Luk surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Luk (2000, 2010, 2020).
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.
