Origin
The surname REF originates from France and is believed to have emerged during the Middle Ages, around the 12th or 13th century. It is thought to have been derived from the Old French word "ref," which means "reef" or "sandbank." This suggests that the name may have been given to someone who lived near a reef or sandbank.
One of the earliest recorded instances of the name REF can be found in the Livre des Métiers, a medieval document from Paris dating back to the 13th century. The text mentions a certain "Jehan le Ref," indicating that the name was already in use at that time.
Another historical reference to the name REF comes from the Hundred Rolls, a series of records commissioned by King Edward I of England in the late 13th century. These rolls contain information about landholders and their properties, and they include several individuals with the surname REF or variations thereof, such as "Robert le Ref" and "William le Reff."
One notable bearer of the name REF was Pierre REF, a French theologian and philosopher who lived in the 14th century (c. 1320-1382). He was known for his work on the philosophical concept of universals and his contributions to the scholastic tradition.
In the 15th century, there was a notable French family named REF who owned land in the region of Brittany. One member of this family, Jehan REF (c. 1425-1498), was a prominent nobleman and military commander who served under several French kings.
Another famous person with the surname REF was the English poet and playwright Thomas REF (c. 1555-1592). Although not much is known about his life, he is remembered for his contribution to English literature, particularly his collection of poems titled "The Phoenix Nest."
As the surname spread throughout Europe, it took on various spellings and forms, such as Reff, Reffe, and Reffé. In some regions, the name was also associated with certain place names, such as the village of Reffuveille in northern France or the town of Reffye in the Burgundy region.
While the surname REF is not as common today as it once was, it remains a part of the rich tapestry of European surnames, reflecting the diverse histories and cultures that have shaped the continent over the centuries.
Demographics
Among Census respondents with the surname Ref, the largest self-reported group is White at 49.3%. The next largest groups are Hispanic (21.2%) and Black (19.6%).
The bar chart below shows how Ref 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 Ref surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Ref (2010, 2020).
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.
