Origin
The surname Seidl originates from Germany, where it first appeared in the late 16th century. It is believed to have derived from the Middle High German word "seide," meaning "silk," and may have referred to an occupation such as a silk merchant or a silk weaver. The name was initially found in Bavaria and other southern regions of Germany.
One of the earliest recorded instances of the Seidl surname can be found in the church records of Augsburg, Bavaria, in the late 16th century. It is also mentioned in various documents from the city of Nuremberg in the early 17th century, suggesting its presence in the region during that time.
The name Seidl has also been associated with certain place names, such as Seidlberg, a village in Upper Austria. This may indicate that the surname could have originated from or been influenced by these geographic locations.
Among the notable individuals who bore the Seidl surname throughout history are Johann Gabriel Seidl (1804-1875), an Austrian composer and conductor, and Anton Seidl (1850-1898), a Hungarian-born conductor who worked extensively in the United States, particularly with the Metropolitan Opera in New York City.
Another prominent figure was Rudolf Seidl (1872-1941), an Austrian-American architect who designed several notable buildings in New York City, including the Manhattan Bridge Arch and the New York Hippodrome Theatre.
In the literary world, Johann Nepomuk Seidl (1793-1853) was a German writer and poet who gained recognition for his ballads and romantic works.
Additionally, Johann Seidl (1857-1938) was an Austrian politician and jurist who served as the Mayor of Vienna from 1918 to 1923, during a crucial period in the city's history.
While these are just a few examples, the Seidl surname has a long and diverse history, spanning various fields and regions, particularly in Germany and Austria, where it first emerged and gained prominence.
Demographics
Among Census respondents with the surname Seidl, the largest self-reported group is White at 93.2%. The next largest groups are Hispanic (2.7%) and Two or More Races (2.2%).
The bar chart below shows how Seidl 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 Seidl 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.
