Origin
The surname Erdie originated in Scotland in the late 13th century. It is derived from the Gaelic word "ard," meaning high or lofty. The name likely referred to someone who lived on a hill or elevated land. Some of the earliest recorded spellings include Ardye, Airdye, and Airdie.
One of the earliest known bearers of the name was John de Arde, who was mentioned in the Ragman Rolls of 1296. The Ragman Rolls were a series of documents that recorded the names of Scottish nobles and landowners who swore allegiance to King Edward I of England.
In the 14th century, the name appeared in various Scottish records, including the Exchequer Rolls of Scotland. One entry from 1369 mentions a payment made to "Willelmo de Arde." This William de Arde was likely a landowner or official in the Scottish government at the time.
The name Erdie has also been linked to several place names in Scotland, such as Airdrie, a town located near Glasgow. The town's name is believed to have originated from the Gaelic "Ard Reidh," meaning "high plain" or "level ground."
One notable bearer of the surname was Sir Thomas Erdie (c. 1560-1624), a Scottish landowner and politician who served as a member of the Scottish Parliament in the early 17th century. He was a supporter of the union between Scotland and England and played a role in the negotiations that led to the Act of Union in 1707.
Another historical figure with the surname Erdie was John Erdie (1673-1747), a Scottish minister and writer. He served as the minister of the parish of Arbuthnott in Kincardineshire and authored several religious works, including "The Practical Expositor" and "The Family Instructor."
Other notable individuals with the surname Erdie include:
1. James Erdie (c. 1580-1637), a Scottish merchant and landowner who owned estates in Perthshire.
2. Robert Erdie (1705-1779), a Scottish architect who designed several churches and public buildings in Edinburgh.
3. Margaret Erdie (1725-1801), a Scottish philanthropist and benefactor who donated funds to establish a school for girls in Aberdeen.
4. William Erdie (1810-1888), a Scottish engineer who played a key role in the construction of the Forth Bridge in Scotland.

Demographics
Among Census respondents with the surname Erdie, the largest self-reported group is White at 89.1%. The next largest groups are Hispanic (8.4%) and Two or More Races (2.5%).
The bar chart below shows how Erdie 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 Erdie 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.
