Origin
The surname Reddin has its origins in Ireland, where it first emerged in the medieval era. It is derived from the Gaelic word "reidhin," which means "little plain" or "little meadow." This suggests that the name may have been initially given to someone who lived near a small, flat area of land.
The earliest recorded instances of the name date back to the 13th century. In 1296, a Robert Redyn is mentioned in the Pipe Rolls of Yorkshire, England. It's possible that this individual was of Irish descent and had emigrated to England.
In Ireland itself, the name can be traced back to County Wexford, where it was particularly prevalent among families in the baronies of Forth and Bargy. One notable individual bearing this surname was Sir Patrick Reddin, a prominent landowner in County Wexford during the 16th century.
Another historical figure with this name was Sir John Reddin, who served as Lord Mayor of Dublin in 1665. He was a prominent merchant and played a significant role in the city's affairs during the latter half of the 17th century.
In the 18th century, the name appears in various records related to County Wexford, such as the Hearth Money Rolls and the Census of Elphin. One individual of note from this period was Edward Reddin, a member of the Irish Parliament who represented the constituency of Fethard between 1761 and 1768.
Moving into the 19th century, the name continued to be associated with County Wexford, but it also spread to other parts of Ireland and beyond. One notable figure was Michael Reddin, born in 1854, who was a prominent lawyer and served as a judge in the Irish Free State after its establishment in 1922.
Additionally, the Reddin surname has been carried by several individuals who made significant contributions in various fields. For example, Thomas Reddin (1805-1862) was an Irish-born Australian politician who served as a member of the Legislative Council of New South Wales.
While the surname Reddin may not be as widespread as some others, it has a rich history and can be traced back to its Irish roots, where it was particularly prevalent in County Wexford. The name has been borne by individuals from various walks of life, including landowners, politicians, lawyers, and judges, over the course of several centuries.
Demographics
Among Census respondents with the surname Reddin, the largest self-reported group is White at 78.7%. The next largest groups are Black (11.5%) and Hispanic (3.9%).
The bar chart below shows how Reddin 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 Reddin 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.
