Origin
The surname Blumberg is believed to have originated in Germany, with its earliest recorded use dating back to the 13th century. The name is derived from the German words "Blume" meaning "flower" and "Berg" meaning "hill" or "mountain." This suggests that the name may have been initially given to someone who lived near a hill or mountain where flowers grew abundantly.
One of the earliest recorded instances of the name Blumberg can be found in the town of Blumberg, located in the Black Forest region of Baden-Württemberg, Germany. The town's name, which means "flower mountain," likely influenced the surname's adoption in the area.
In the 14th century, a record from the town of Blumberg mentions a person named Hans Blumberg, who may have been one of the first known individuals to bear this surname. Another early reference to the name can be found in the "Codex Diplomaticus Brandenburgensis," a collection of historical documents from the 14th century, which mentions a certain "Henricus de Blumenberg."
Throughout the centuries, several notable individuals have carried the Blumberg surname. One of the earliest was Johannes Blumberg (c. 1450-1519), a German humanist and scholar who taught at the University of Leipzig and was known for his contributions to the study of classical literature.
In the 17th century, Johann Ludwig Blumberg (1629-1686) was a German composer and organist who served as the court musician for the Elector of Brandenburg. His compositions, particularly his organ works, were highly regarded during his time.
In the 19th century, Raphael Blumberg (1826-1889) was a prominent Austrian architect known for his work on numerous buildings in Vienna, including the Palais Ephrussi and the Synagogue in the Seitenstettengasse.
Another notable figure was Max Blumberg (1885-1925), a German-born American chess master and writer who authored several books on chess strategy and tactics. He was also a skilled player and won several tournaments in the early 20th century.
More recently, Ralph Blumberg (1930-2016) was an American business executive and philanthropist who served as the chairman and CEO of the Rockefeller Foundation. He was recognized for his contributions to promoting sustainable development and addressing global health issues.
These examples highlight the diverse backgrounds and achievements of individuals who have carried the Blumberg surname throughout history, originating from its roots in the German language and its connection to the town of Blumberg in the Black Forest region.
Demographics
Among Census respondents with the surname Blumberg, the largest self-reported group is White at 89.2%. The next largest groups are Hispanic (6.8%) and Two or More Races (2.6%).
The bar chart below shows how Blumberg 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 Blumberg surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Blumberg (2000, 2010, 2020).
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.
