Origin
The surname McLaurin originates from Scotland and dates back to the 12th century. It is a clan name derived from the Gaelic Mac Labhruinn, meaning "son of the freckled man." The name was particularly common in the regions of Argyll and the Western Isles.
One of the earliest recorded instances of the name can be found in the Ragman Rolls of 1296, where Gillechrist McLourin is listed as a landowner who swore fealty to King Edward I of England. In the 15th century, a branch of the McLaurins settled in the district of Knapdale in Argyllshire.
The name is also associated with the village of Kilbride, which was formerly known as Kilmolarn or Kilmolaurin, likely named after an early clan chief. In the 16th century, a notable figure was John McLaurin, a minister who served as the Dean of Moray and was involved in negotiations between the Scottish and English crowns.
During the 17th century, several McLaurins gained prominence, including Sir John McLaurin (1615-1684), a Scottish lawyer and judge, and John McLaurin (1693-1754), a Presbyterian minister and author who was born in Kilmichael, Argyll, and later served as a pastor in Glasgow and Edinburgh.
In the 18th century, Colin McLaurin (1698-1746), a renowned Scottish mathematician and geometer, made significant contributions to the study of calculus and was elected to the Royal Society in 1719. He is best known for the McLaurin series, a mathematical tool used in calculus.
Other notable individuals with the surname include John McLaurin (1834-1886), a Scottish-American educator and Presbyterian minister who served as the president of the University of South Carolina, and James Mclaurin (1901-1976), an American judge and civil rights leader who played a crucial role in the desegregation of public schools in South Carolina.
Demographics
Among Census respondents with the surname Mclaurin, the largest self-reported group is Black at 62.6%. The next largest groups are White (27.9%) and Two or More Races (5.8%).
The bar chart below shows how Mclaurin 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 Mclaurin 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 Mclaurin (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.
