Origin
The surname "Roach" is believed to have originated in England, where it first appeared in records during the 13th century. It is thought to have derived from the Old English word "rohha," which referred to a small, elongated fish, or the Middle English word "roche," meaning a rock or rocky outcrop.
One of the earliest documented instances of the name can be found in the Pipe Rolls of Worcestershire from the year 1275, which mention a person named Adam le Roche. The name was likely an occupational surname, given to someone who lived near a rocky area or worked with fish.
In the 14th century, the surname appears in various forms, such as "de la Roche," "atte Roche," and "Roche," reflecting the evolving spelling and usage of the name over time. One notable reference is found in the Chancery Rolls of 1386, which record a John de la Roche from Gloucestershire.
During the 16th and 17th centuries, the name underwent further changes, with spellings like "Roache," "Roach," and "Roche" becoming more common. One prominent individual from this era was Sir William Roach (c. 1580-1647), an English diplomat and Member of Parliament.
Another noteworthy figure was John Roach (1815-1887), an Irish-American shipbuilder and industrialist who established the renowned Roach Shipyard in Chester, Pennsylvania. He played a significant role in the development of the American shipbuilding industry during the 19th century.
In the realm of literature, Max Roach (1924-2007) was an influential American jazz drummer, percussionist, and composer who made significant contributions to the development of bebop and modern jazz.
Other individuals with this surname include Darren Roach (born 1972), an English former professional footballer, and Andrew Roach (born 1980), an American actor known for his roles in television series such as "Desperate Housewives" and "Supernatural."
While the surname "Roach" has evolved over the centuries and spread to various parts of the world, its origins can be traced back to the rocky landscapes and fishing communities of medieval England.
Demographics
Among Census respondents with the surname Roach, the largest self-reported group is White at 77.2%. The next largest groups are Black (13.5%) and Two or More Races (4.3%).
The bar chart below shows how Roach 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 Roach 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.
