Origin
The surname Egan has its origins in Ireland, where it first emerged as a variant of the Gaelic name Ó hAodhagáin, meaning "descendant of Aodhagán." Aodhagán itself is a diminutive form of the name Aodh, meaning "fire."
The Egan surname is most closely associated with County Offaly and County Tipperary, where it has been present since the Middle Ages. It is believed to have originated as a patronymic name, indicating a family's descent from a particular ancestor.
One of the earliest recorded instances of the Egan name can be found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the early 17th century. The annals mention an individual named Conchobhar Ó hAodhagáin, who was the Chief of Ui Fiachrach in County Sligo, in the year 1182.
In the 16th century, the Egan family was prominent in County Offaly, where they held lands in the baronies of Geashill and Philipstown. Notable members from this period include Terence Egan, a member of the Irish Parliament in 1585, and William Egan, who was appointed Sheriff of County Offaly in 1596.
During the Irish Confederate Wars of the 1640s, several Egans played significant roles, including John Egan, who served as a captain in the Confederate Catholic forces, and Rory Egan, a prominent landowner in County Offaly who supported the Catholic cause.
In the 18th century, Patrick Egan (1670-1759) was a renowned historian and genealogist from County Offaly, who compiled a detailed account of the Egan family's history and lineage.
Another notable figure was John Egan (1784-1858), a Catholic priest and educator from County Tipperary, who played a key role in establishing primary schools and promoting education in his local community.
As the Egan name spread throughout Ireland and beyond, it has been associated with various notable individuals, including the American writer and activist Terry Egan (1939-2019), and the Australian rugby league player and coach Kevin Egan (born 1957).
Demographics
Among Census respondents with the surname Egan, the largest self-reported group is White at 92.0%. The next largest groups are Hispanic (3.6%) and Two or More Races (2.5%).
The bar chart below shows how Egan 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 Egan 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.
