Origin
The surname Neilson has its origins in Scotland, dating back to the 13th century. It is a patronymic name derived from the personal name Neil, which is a Scottish form of the Gaelic name Niall, meaning "champion" or "cloud." The suffix "-son" indicates "son of."
The earliest recorded instances of the name can be found in the Exchequer Rolls of Scotland from the late 13th century, where individuals with the name Neilson are mentioned. These rolls were records of financial transactions and taxes paid to the Scottish Crown.
One of the earliest known bearers of the name was John Neilson, a Scottish landowner and nobleman who lived in the late 14th century. He was recorded as owning lands in the county of Ayrshire, which suggests that the name may have originated in that region.
In the 16th century, the name Neilson appears in the records of the Scottish Parliament, where several individuals with this surname are mentioned as representatives from various shires and burghs.
A notable bearer of the name was Samuel Neilson (1761-1803), an Irish Presbyterian minister and political activist who was a leading figure in the Society of United Irishmen, a revolutionary republican movement in the late 18th century.
Another prominent individual was John Neilson (1776-1848), a Canadian newspaper publisher and journalist who founded the Quebec Gazette, one of the oldest continuously published newspapers in North America.
In the 19th century, James Beaumont Neilson (1792-1865) was a Scottish engineer and inventor who developed the hot blast process for smelting iron, which significantly increased the efficiency of blast furnaces and revolutionized the iron industry.
Further instances of the name can be found in various historical records and documents, such as court records, parish registers, and census records, across Scotland and other parts of the United Kingdom, as well as in areas where Scottish immigrants settled, such as North America and Australia.
The surname Neilson has also been subject to various spelling variations over time, including Neilson, Nielson, Nelson, and Nilson, among others, reflecting regional differences in pronunciation and spelling conventions.
Demographics
Among Census respondents with the surname Neilson, the largest self-reported group is White at 89.8%. The next largest groups are Two or More Races (3.6%) and Hispanic (3.4%).
The bar chart below shows how Neilson 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 Neilson 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.
