Origin
The surname Dorough is believed to have originated in England, likely during the medieval period. It is thought to be a variant spelling or dialectal form of the Old English surname Duerhugo, which was derived from the Old English words "dure" meaning "door" and "hugo" meaning "heart" or "courage." This combination suggests the name may have been given to a brave doorkeeper or gatekeeper.
One of the earliest recorded instances of the name Dorough can be found in the Subsidy Rolls of Staffordshire from 1327, where a Thomas Dorewarthe is mentioned. This spelling variation provides insight into the name's evolution over time.
In the 15th century, the surname appears in various historical records from different regions of England. For example, a John Dorowgh is documented in the Court Rolls of the Manor of Wakefield in Yorkshire in 1459.
The Dorough name has also been associated with certain place names in England, such as the village of Dorough in Somerset, which may have influenced the surname's development.

Demographics
Among Census respondents with the surname Dorough, the largest self-reported group is White at 87.1%. The next largest groups are Hispanic (5.1%) and Two or More Races (4.1%).
The bar chart below shows how Dorough 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 Dorough 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.
