Origin
The surname Alsup is believed to have originated in England, specifically in the northern counties of Yorkshire and Lancashire. It is thought to be derived from the Old English words "ald" meaning "old" and "hup" or "hop" meaning a small hill or mound. Thus, Alsup may have initially referred to someone who lived near an old hill or mound.
One of the earliest recorded instances of the name Alsup can be found in the Domesday Book of 1086, a great survey of land and property commissioned by William the Conqueror. The name appears as "Aldehop," likely referring to a settlement or place name that later evolved into the surname.
In the 13th century, the name was recorded as "Aldhop" and "Aldehope" in various Yorkshire records, indicating the gradual transition to its modern spelling. During this period, the surname was primarily concentrated in the northern counties of England.
Notable individuals bearing the Alsup surname include Richard Alsup, a prominent landowner in Yorkshire who was mentioned in the Pipe Rolls of 1166. John Alsup, born in 1542 in Lancashire, was a respected scholar and theologian who authored several religious works.
In the 17th century, William Alsup (1620-1679) was a successful merchant and trader in London, contributing to the city's thriving economy. His son, Thomas Alsup (1654-1718), followed in his footsteps and became a respected figure in the London merchant community.
During the 19th century, the surname gained recognition with the birth of Sir Joseph Alsup (1816-1892), a renowned English barrister and judge who presided over several high-profile cases during his career.
As the surname spread across England and beyond, different variations and spellings emerged, such as Alsopp, Alshopp, and Allsop. However, the Alsup spelling remained predominantly used by families with roots in the northern counties of Yorkshire and Lancashire.
Demographics
Among Census respondents with the surname Alsup, the largest self-reported group is White at 82.9%. The next largest groups are Black (8.2%) and Two or More Races (4.9%).
The bar chart below shows how Alsup 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 Alsup 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.
