Origin
The surname NASS originated in Germany during the late medieval period. It is believed to have derived from the German word "nass," which means "wet" or "damp." This suggests that the name may have been initially given as a descriptive nickname to someone who lived near a body of water or in a particularly rainy area.
One of the earliest documented references to the surname NASS can be found in the records of the city of Cologne, where a certain Johannes Nass was mentioned in a legal document dated 1387. In the 15th century, the name appeared in various forms, such as Nasse and Nassen, in different regions of Germany.
During the 16th century, the surname NASS started to spread beyond Germany's borders. In 1521, a merchant named Hans Nass was recorded in the city archives of Amsterdam, indicating that the name had made its way to the Netherlands.
One notable historical figure bearing the surname NASS was Johann Nass, a German Protestant theologian and reformer who lived from 1534 to 1590. He played a significant role in the Reformation movement and authored several influential works on theology and church doctrine.
Another noteworthy individual with the surname NASS was Johann Matthias Nass, a German composer and violinist who lived from 1685 to 1763. He was a renowned musician in his time and served as the court composer for the Prince of Hesse-Darmstadt.
In the 18th century, the surname NASS appeared in various records across Europe. For example, a certain Johann Nass was listed as a landowner in the village of Mönchengladbach, located in present-day North Rhine-Westphalia, Germany, in 1732.
As people began to migrate to different parts of the world, the surname NASS spread further. In the 19th century, there were instances of individuals bearing the name NASS in areas such as the United States and Canada, likely descendants of German immigrants.
It is worth noting that the surname NASS may also have originated independently in other parts of Europe or even other parts of the world, as similar-sounding names can sometimes arise spontaneously in different regions due to shared linguistic roots or descriptive meanings.
Demographics
Among Census respondents with the surname Nass, the largest self-reported group is White at 92.2%. The next largest groups are Two or More Races (2.9%) and Hispanic (2.6%).
The bar chart below shows how Nass 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 Nass 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.
