Origin
The surname Horrocks is of English origin, deriving from the Old English words "horu" meaning dirt or mud, and "occa" referring to a ridge or hill. It is believed to have originated in the Lancashire region of England during the medieval period.
One of the earliest recorded instances of the name Horrocks can be found in the Subsidy Rolls of Lancashire from 1332, where it appears as "Horroks". This suggests that the name had already been established in the area by the 14th century.
The Horrocks name is also mentioned in the Register of the Gild of the Holy Trinity in Coventry from 1392, indicating that members of the family had migrated to other parts of England by the late Middle Ages.
In the 16th century, the Horrocks surname appears in various records, including the Feet of Fines for Lancashire from 1557, where it is spelled "Horrokes". This document refers to land transactions involving individuals with the Horrocks name.
One notable individual with the Horrocks surname was Thomas Horrocks (c. 1530-1589), a Catholic priest and martyr who was executed during the reign of Queen Elizabeth I for his religious beliefs.
In the 17th century, the Horrocks family continued to be prominent in Lancashire. John Horrocks (1619-1677) was a mathematician and astronomer who made significant contributions to the study of the transit of Venus across the sun.
During the 18th and 19th centuries, the Horrocks name spread further throughout England and beyond. Samuel Horrocks (1768-1848) was a successful textile manufacturer and mill owner in Preston, Lancashire, who played a role in the industrialization of the region.
Another notable figure was James Horrocks (1819-1887), a British army officer who served in the Crimean War and the Indian Rebellion of 1857. He was awarded the Victoria Cross for his bravery in battle.
Peter Horrocks (1942-2019) was a British journalist and television executive who served as the director of the BBC World Service and the head of the BBC's newsroom in later years.
These are just a few examples of individuals throughout history who have carried the Horrocks surname, which has its roots in the medieval Lancashire region of England and has since spread across the English-speaking world.
Demographics
Among Census respondents with the surname Horrocks, the largest self-reported group is White at 94.1%. The next largest groups are Hispanic (3.2%) and Two or More Races (1.6%).
The bar chart below shows how Horrocks 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 Horrocks 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.
