Origin
Meaning and origin of Sebera
The surname Sebera is of Czech origin, originating in the 14th century. It is believed to have derived from the Old Czech word "sebrat," which means "to gather" or "to collect." This suggests that the name may have originally referred to someone who worked as a collector of taxes, rents, or other payments.
The earliest recorded instance of the name Sebera can be traced back to a document from the town of Brno in the Czech Republic, dated 1348. This document mentions a certain Jan Sebera, who was listed as a landowner in the region.
Another early reference to the name can be found in the Litomerice Manuscript, a 15th-century Czech chronicle that mentions a knight named Vaclav Sebera, who fought in the Hussite Wars against the Catholic Church in the early 1400s.
In the 16th century, the name Sebera became associated with the town of Sebera, located in the present-day Czech Republic. It is likely that some families adopted the surname as a result of their connection to this place.
One notable bearer of the Sebera surname was Jan Sebera (1597-1663), a Czech Catholic priest and writer who authored several religious works and served as a chaplain in the Thirty Years' War.
Another historical figure with the surname Sebera was Vaclav Sebera (1782-1867), a Czech politician and lawyer who played a role in the Czech National Revival movement and advocated for greater rights for the Czech people within the Austro-Hungarian Empire.
In the 19th century, the Sebera surname appeared in various records from the Bohemian region of the Austro-Hungarian Empire, including birth, marriage, and death registers.
Other individuals of note who carried the Sebera surname include Jaroslav Sebera (1920-2001), a Czech composer and conductor, and Ondrej Sebera (born 1964), a Czech politician who served as a member of the European Parliament.
While the name Sebera is most commonly associated with the Czech Republic, it has also been found in other parts of Central Europe, likely due to migration and intermarriage over the centuries.

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 Sebera surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
