Origin
The surname Birkmaier originated in the German-speaking regions of Europe, particularly in Bavaria and southern Germany. It likely emerged as a hereditary surname during the late medieval period, around the 13th or 14th century.
The name Birkmaier is derived from the combination of two German words: "Birk" meaning "birch tree" and "maier" or "meier," which referred to a manager or official of an estate or farm. This suggests that the earliest bearers of this surname may have been stewards, overseers, or administrators associated with estates or manors located near birch trees or birch forests.
One of the earliest recorded instances of the name Birkmaier can be found in the Bairische Stammtafeln, a collection of genealogical records from Bavaria, dating back to the 15th century. The name is also mentioned in various municipal archives and church records from southern Germany during the 16th and 17th centuries.
Notable individuals with the surname Birkmaier include Johann Birkmaier (1630-1698), a German theologian and author who served as a Lutheran pastor in Nuremberg. Another prominent figure was Philipp Birkmaier (1815-1882), a Bavarian politician and member of the Reichstag, the national parliament of the German Empire.
In the 18th century, a family of Birkmaiers settled in the village of Kirchberg an der Jagst in Württemberg, where they established a successful brewery. The most renowned member of this branch was Georg Birkmaier (1787-1866), a respected brewer and entrepreneur.
Other historical figures bearing the surname Birkmaier include Friedrich Birkmaier (1874-1945), a German architect who designed several notable buildings in Munich, and Katharina Birkmaier (1895-1978), a German-born artist and painter who emigrated to the United States in the 1920s and became known for her landscape paintings depicting scenes from the American Southwest.
While the name Birkmaier is most commonly found in Germany, Austria, and Switzerland, it has also spread to other parts of the world through emigration, particularly to North America, where descendants of German immigrants have carried on the surname.
Demographics
Among Census respondents with the surname Birkmaier, the largest self-reported group is White at 92.6%. The next largest groups are Hispanic (4.6%) and Black (0.9%).
The bar chart below shows how Birkmaier 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 Birkmaier 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.
