Origin
The surname Caughey has its origins in Ireland. It is an Anglicized version of the Irish Gaelic name O'Caidhidh, which means "descendant of Caidhidh." Caidhidh is a personal name derived from the word "cadha," meaning "kind" or "gentle."
This surname can be traced back to County Armagh, a region in Northern Ireland, where it was first recorded in the 16th century. The earliest known spelling of the name was Caha or Caha, which eventually evolved into Caughey.
One of the earliest references to the name Caughey can be found in the Fiants of the Reign of Elizabeth I, a collection of Irish documents from the late 16th century. This record mentions a land grant given to a certain "John Caha" in County Armagh.
In the 17th century, during the Plantation of Ulster, many Caugheys were among the Scottish and English settlers who were granted lands in Ireland. This led to the further spread and establishment of the surname in various parts of the island.
Notable individuals with the surname Caughey include:
1. James Caughey (1810-1891), an American Methodist evangelist and revivalist preacher who was born in Ireland.
2. John Caughey (1788-1858), an Irish-born American Methodist minister and author.
3. Patrick Caughey (1767-1835), an Irish Roman Catholic priest and philosopher.
4. William Caughey (1788-1866), an Irish-born American Methodist minister and author, brother of John Caughey.
5. Samuel Caughey (1807-1871), an Irish-born American Methodist minister and educator.

Demographics
Among Census respondents with the surname Caughey, the largest self-reported group is White at 93.3%. The next largest groups are Two or More Races (4.3%) and Hispanic (1.7%).
The bar chart below shows how Caughey 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 Caughey 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 Caughey (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.
