Origin
The surname Baum is of German origin, derived from the German word "Baum," which means "tree." It is thought to have originated as a descriptive surname, likely referring to someone who lived near a notable tree or forest.
The earliest known recorded instances of the name Baum date back to the 13th century in various regions of Germany. In 1295, a Henrich Boum was mentioned in records from the town of Meiningen, in the modern-day state of Thuringia. Around the same time, a Conradus dictus Boum was recorded in the town of Schlitz, in the state of Hesse.
Throughout the Middle Ages, the name appeared in various spellings, such as Baume, Bawm, and Bawme, reflecting regional variations in pronunciation and spelling conventions of the time. The name was also sometimes associated with place names containing the word "Baum," such as Baumgarten (meaning "tree garden") or Baumbach (meaning "tree stream").
One of the earliest notable individuals with the surname Baum was Johann Baum, a German theologian and reformer born in Nuremberg in 1515. He played a role in the Protestant Reformation and was a contemporary of Martin Luther.
Another historical figure with the surname Baum was Johann Wilhelm Baum, a German botanist and botanographer born in 1719. He is known for his work in cataloging and describing plant species, particularly in the genus Rubus (the raspberry and blackberry family).
In the 19th century, the name Baum was borne by several notable individuals, including the German-American writer and editor Lyman Frank Baum (1856-1919), best known as the author of the beloved children's novel "The Wonderful Wizard of Oz." Another 19th-century figure was the German politician and statesman Ludwig Bamberger (1823-1899), who served as a member of the Reichstag and played a prominent role in the unification of Germany.
In the arts, the name Baum is associated with the German expressionist painter and printmaker Sonia Delaunay-Terk (née Baum, 1885-1979), a co-founder of the Orphism art movement and a pioneering figure in abstract art.
Throughout history, the surname Baum has been carried by individuals from various walks of life, including scholars, artists, politicians, and others who have made significant contributions to their respective fields.
Demographics
Among Census respondents with the surname Baum, the largest self-reported group is White at 91.3%. The next largest groups are Hispanic (3.2%) and Two or More Races (3.0%).
The bar chart below shows how Baum 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 Baum 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.
