Origin
The surname Meagher is of Irish origin and can be traced back to the County Tipperary area of Ireland. It is an anglicized version of the Irish Gaelic name "Ó Meachair", which means "descendant of Meachair". Meachair is derived from the word "meacair", meaning "hospitable" or "affable".
The name first appeared in historical records in the 12th century, when it was commonly spelled "O'Meagher". It is believed that the Meagher clan was originally based in the territory of Ikerrin, which was located in what is now County Tipperary. The Meaghers were a prominent family in this region and played a significant role in Irish history.
One of the earliest recorded instances of the name is in the Annals of Inisfallen, a chronicle of medieval Irish history, which mentions a "Meagher of Ikerrin" in the year 1200. The name also appears in the Annals of the Four Masters, another important source for Irish history, in the 14th century.
In the 16th century, during the Tudor conquest of Ireland, the Meagher clan was involved in several conflicts with the English forces. One notable figure from this period was Thomas Meagher, who led a rebellion against the English in 1548. He was eventually captured and executed.
Another famous bearer of the name was Thomas Francis Meagher (1823-1867), an Irish revolutionary and leader of the Young Irelanders. He was a prominent figure in the Irish Rebellion of 1848 and was later transported to Van Diemen's Land (now Tasmania) as a convict. After his release, he emigrated to the United States and served as a Brigadier General in the Union Army during the American Civil War.
Other notable Meaghers include William Meagher (1796-1874), an Irish politician and landowner, and John Francis Meagher (1824-1891), a Canadian businessman and politician who served as the first Speaker of the House of Commons of Canada.
The name Meagher has also been associated with various place names in Ireland, such as Meaghers' Country, a region in County Tipperary, and Meagher's Fort, a historic site in County Cork.
Demographics
Among Census respondents with the surname Meagher, the largest self-reported group is White at 92.7%. The next largest groups are Hispanic (3.2%) and Two or More Races (2.3%).
The bar chart below shows how Meagher 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 Meagher 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 Meagher (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.
