Origin
The surname LEWIS originated in Britain, derived from the Old French personal name "Lew(i)s", which was the Norman form of the Germanic name "Hludwig" or "Chlodovech". This name comes from the elements "hlud" meaning "loud" or "famous" and "wig" meaning "war" or "warrior". The name was introduced to Britain after the Norman Conquest of 1066.
The earliest recorded instances of the LEWIS surname date back to the late 11th century in England. One of the earliest known bearers was Radulphus Leu(u)is, who was recorded in the Domesday Book of 1086, a survey commissioned by William the Conqueror. The name was prevalent in various counties across England, including Shropshire, Warwickshire, and Gloucestershire.
In the 13th century, the surname was also recorded in Wales, where it was likely adopted by those of Norman descent or by Welsh individuals who adopted the name. The earliest known record in Wales is of a Leuwys ap Gruffydd, who lived in Denbighshire in the late 13th century.
Throughout history, the LEWIS surname has been associated with various notable individuals. One of the most famous was Meriwether Lewis (1774-1809), the American explorer who led the Lewis and Clark Expedition across the western United States. Another notable bearer was C.S. Lewis (1898-1963), the renowned British writer and scholar best known for his Chronicles of Narnia fantasy series.
Other notable figures with the LEWIS surname include Carl Lewis (born 1961), the American Olympic track and field athlete; Jerry Lee Lewis (1935-2022), the American rock and roll pioneer; and Sinclair Lewis (1885-1951), the American novelist and playwright who won the Nobel Prize in Literature in 1930.
Over time, the LEWIS surname has evolved and been spelled in various ways, including Lewys, Leuwis, and Llewis, particularly in Wales. Additionally, some place names in Britain, such as Lewisham in London and Lewistown in Wales, are believed to have derived from the surname.
Demographics
Among Census respondents with the surname Lewis, the largest self-reported group is White at 55.7%. The next largest groups are Black (34.0%) and Two or More Races (4.8%).
The bar chart below shows how Lewis 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 Lewis 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.
