Origin
Meaning and origin of Hass
The surname Hass is of German origin and dates back to the early medieval period. It is thought to have derived from the Old High German word "has," meaning a rabbit or hare. This suggests that the name may have originally referred to someone who worked with rabbits or lived in an area where rabbits were abundant.
One of the earliest recorded instances of the name Hass can be found in the Codex Traditionum Corbeiensium, a medieval manuscript from the Benedictine abbey of Corvey in present-day North Rhine-Westphalia, Germany. This document, dating back to the 9th century, mentions a man named Hasso, which is believed to be a variant spelling of the surname Hass.
In the 11th century, the name Hasso appeared in the Annales Corbeienses, a chronicle of the abbey of Corvey. This suggests that the name was well-established in the region during this time period. It is possible that the name Hass may have been derived from place names containing the word "Has" or "Hass," such as Hasselbach or Hasselbach-Weidenau in Hesse, Germany.
One notable figure in history who bore the surname Hass was Johann Matthias Hass (1684-1742), a German composer and organist who lived in the Baroque period. He was born in Hausfeld, near Halberstadt, and is best known for his organ works and sacred compositions.
Another individual of historical significance was Johann Adolf Hass (1713-1795), a German painter and engraver from Nuremberg. He is particularly renowned for his engravings of works by renowned artists such as Rembrandt and Rubens.
In the 19th century, Friedrich Hass (1808-1881) was a German chemist and inventor from Kassel. He is credited with developing a process for the industrial production of potassium chlorate, which had significant applications in the manufacturing of matches and explosives.
The surname Hass has also been associated with notable figures in the field of literature. One example is Petrus Hass (1618-1667), a German poet and dramatist from Nuremberg who wrote plays and poems in both German and Latin.
Finally, it is worth mentioning Johann Gottfried Hass (1744-1829), a German painter and art teacher from Nuremberg. He was a prominent figure in the Nuremberg art scene and is particularly known for his portrait paintings and religious works.

The bar chart below shows how Hass 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 Hass surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Hass (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
