Origin
The surname GASS has its origins in the German language, with its earliest known records dating back to the 13th century. It is believed to have derived from the Old German word "gast," which meant "guest" or "stranger." This name was likely given to someone who had settled in a new area or was considered a newcomer.
One of the earliest recorded mentions of the surname GASS can be found in a document from the German town of Esslingen, dated 1285. The document refers to a certain "Conradus dictus Gast," which translates to "Conrad, called Guest." This suggests that the name was initially used as a descriptive nickname before becoming a hereditary surname.
In the 14th century, the surname GASS appeared in various forms, such as "Gast," "Gest," and "Geste," in various regions of Germany, including Bavaria, Saxony, and Swabia. The variations in spelling were common during this period, as standardized spellings were not yet established.
A notable early bearer of the surname was Johann Gass, a German theologian and philosopher who lived from 1498 to 1552. He was a prominent figure in the Protestant Reformation and authored several influential works on theology and ethics.
Another significant figure was Johann Gass, a German composer and organist who lived from 1674 to 1737. He is remembered for his contributions to the development of the organ concerto and his works for the Lutheran church.
In the 18th century, the surname GASS spread beyond Germany to other parts of Europe and eventually to the Americas. One notable bearer was Joachim Gass, a German-American pioneer and fur trader who lived from 1766 to 1835. He played a significant role in the exploration and settlement of the American West.
In the 19th century, the surname GASS was found in various regions of the United States, particularly in areas with significant German immigration. One notable figure from this period was Patrick Gass, an American soldier and explorer who lived from 1771 to 1870. He was a member of the famous Lewis and Clark Expedition and kept a detailed journal of their journey across the western United States.
As the GASS surname spread across different regions and cultures, its spelling and pronunciation evolved. However, its origins can be traced back to the German word "gast," which served as a descriptive nickname for those who were considered newcomers or guests in a particular area.
Demographics
Among Census respondents with the surname Gass, the largest self-reported group is White at 84.4%. The next largest groups are Black (7.4%) and Two or More Races (3.5%).
The bar chart below shows how Gass 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 Gass 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.
