Origin
The surname ERNST originates from Germany and dates back to the Middle Ages. It is derived from the Germanic given name Ernst, which means "stern" or "serious." The name's earliest known use as a surname can be traced back to the 12th century in the present-day German states of Bavaria and Saxony.
In the 13th century, the surname ERNST appeared in various Latin documents and medieval records across German-speaking regions. One notable mention is in the Codex Traditionum Corbeiensium, a medieval cartulary from the Benedictine abbey in Corvey, which lists several individuals with the surname ERNST.
The surname ERNST was also found in the Bairische Stammtafeln, a collection of genealogical records from Bavaria, dating back to the 14th century. This suggests that the name was well-established in southern Germany during this period.
One of the earliest recorded individuals with the surname ERNST was Johann ERNST, a German scholar and philosopher who lived from 1454 to 1513. He was a professor at the University of Ingolstadt and wrote extensively on theology and logic.
Another notable figure was Valerius ERNST, a German composer and organist who lived from 1570 to 1630. He was employed at the court of the Dukes of Brunswick-Lüneburg and is known for his sacred compositions and instrumental works.
In the 17th century, the surname ERNST spread to other parts of Europe. For example, Johann Arnold ERNST was a Dutch artist and engraver who lived from 1623 to 1685. He is renowned for his intricate landscape etchings and prints.
Moving to the 19th century, Heinrich Wilhelm ERNST was a German violinist and composer who lived from 1814 to 1865. He was a virtuoso performer and wrote several influential works for the violin, including his renowned Élégie.
Another notable figure was Max ERNST, a German painter and sculptor who played a pivotal role in the Dada and Surrealist movements. He lived from 1891 to 1976 and is celebrated for his innovative techniques and surreal imagery.
Demographics
Among Census respondents with the surname Ernst, the largest self-reported group is White at 92.1%. The next largest groups are Hispanic (3.3%) and Two or More Races (2.9%).
The bar chart below shows how Ernst 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 Ernst 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.
