The earliest recorded instances of the surname Orr can be traced back to the 13th century in Scotland. One of the earliest recorded bearers of the name was Adam Ore, who was mentioned in the Ragman Rolls of 1296, a historical record of Scottish landowners who swore fealty to King Edward I of England.
In the 16th century, the surname Orr was found in various parts of Scotland, particularly in the counties of Ayrshire, Renfrewshire, and Lanarkshire. The name was also associated with the island of Orr (sometimes spelled Ore), located in the Firth of Clyde off the coast of Ayrshire.
Notable historical figures bearing the surname Orr include Robert Orr (c. 1675-1711), a Scottish Presbyterian minister and philosopher, and Sir Andrew Orr (1806-1892), a Scottish businessman and philanthropist who founded the Orr Ewing & Co. textile manufacturing company in Glasgow.
In the 17th century, the surname Orr was also found in the Ulster Plantation in Ireland, where many Scottish settlers established themselves. One of the earliest recorded instances of the name in Ireland was that of John Orr, who was granted land in County Antrim in 1610.
Other notable individuals with the surname Orr include James Orr (1844-1913), a Canadian politician and businessman; Sir John Boyd Orr (1880-1971), a Scottish biologist and nutritionist who received the Nobel Peace Prize in 1949; and Mary Orr (1914-2008), an American film actress known for her roles in several popular films in the 1930s.
The surname Orr has also been found in various spellings over the centuries, including Ore, Oure, and Orre, reflecting the variations in pronunciation and spelling conventions in different regions and time periods.
Demographics
Among Census respondents with the surname Orr, the largest self-reported group is White at 76.4%. The next largest groups are Black (14.7%) and Two or More Races (4.2%).
The bar chart below shows how Orr 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 Orr 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.
