Origin
The surname Wirth originated in Germany and is derived from the German word "wirt", meaning innkeeper or host. It first appeared in the 12th century in the regions of Bavaria and Swabia, where many inns and taverns were located along trade routes.
The earliest recorded instances of the name date back to the 13th century, such as Henricus Wirt, mentioned in a document from 1243 in the town of Nuremberg. Similar spellings like Wirth, Wyrth, and Wuerth were also common in medieval records.
One notable bearer of the name was Johannes Wirth, a 15th-century German mathematician and astronomer born in Nuremberg around 1437. He is known for his work on planetary motion and the calculation of eclipses.
In the 16th century, the name Wirth appeared in the Duchy of Württemberg, where a village called Wirth existed. This place name likely contributed to the prevalence of the surname in that region.
Another significant figure was Johann Georg Wirth, a German philosopher and theologian born in 1654 in Nuremberg. He wrote extensively on metaphysics and the philosophy of religion.
The surname Wirth also has a long history in Switzerland, particularly in the canton of Zurich. One notable Swiss bearer was Max Wirth, a 19th-century writer and journalist born in 1822 in Winterthur. He was known for his travel writings and his advocacy for Swiss nationalism.
In the 20th century, the name gained prominence in the field of computer science with the work of Niklaus Wirth, a Swiss computer scientist born in 1934 in Winterthur. He is credited with developing several programming languages, including Pascal and Modula-2, and has made significant contributions to compiler design and software engineering.
Demographics
Among Census respondents with the surname Wirth, the largest self-reported group is White at 92.1%. The next largest groups are Hispanic (3.5%) and Two or More Races (2.9%).
The bar chart below shows how Wirth 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 Wirth 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.
