The surname McMullin is of Irish origin and can be traced back to the 16th century. It is an Anglicized form of the Gaelic name "Mac Maolín," which means "son of the devotee." The name is derived from the Irish word "maol," meaning "bald" or "tonsured," and "ín," a diminutive suffix, indicating a small or young person.
The McMullin surname is predominantly found in the northern counties of Ireland, particularly in counties Antrim, Derry, and Tyrone. It is believed that the name originated in these areas, where it was first recorded in the late 16th and early 17th centuries.

In the 17th century, the name appears in various historical documents, including the Muster Rolls of the Irish Confederate Wars (1641-1653) and the Hearth Money Rolls of County Antrim (1663-1666).

Demographics
Among Census respondents with the surname Mcmullin, the largest self-reported group is White at 86.7%. The next largest groups are Black (4.5%) and Two or More Races (4.1%).
The bar chart below shows how Mcmullin 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 Mcmullin 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 Mcmullin (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.
