Origin
The surname Benowitz is of Ashkenazi Jewish origin. It is believed to have originated in the shtetls of Eastern Europe, particularly in Poland and Russia, in the 17th century. The name is a derivation of the Hebrew name "Ben Avitus," which translates to "son of Avitus."
Avitus was a common given name among Jews in medieval times, derived from the Latin name "Avitus," which means "ancestral" or "inherited." The addition of the suffix "-owitz" or "-vich" was a Slavic way of indicating patronymic surnames, meaning "son of."
One of the earliest documented references to the Benowitz surname can be found in the Revision Lists, which were census records maintained by the Russian Empire for tax purposes. These lists mention several Benowitz families living in the Pale of Settlement, a region designated for Jewish settlement in the late 18th century.
In the early 19th century, a notable figure named Moshe Benowitz was a respected rabbi and scholar in the town of Kobryn, now located in Belarus. He authored several works on Jewish law and theology.
As Jews emigrated from Eastern Europe to other parts of the world in the late 19th and early 20th centuries, the Benowitz surname spread to various countries. One notable bearer of the name was Shmuel Benowitz (1892-1981), a prominent Zionist leader and activist who played a key role in the establishment of the State of Israel.
Another historical figure was Max Benowitz (1915-1988), a Polish-born writer and journalist who survived the Holocaust and later documented his experiences in several books and memoirs.
In the United States, one of the earliest recorded instances of the Benowitz surname was in the late 19th century, when several Benowitz families settled in New York City, fleeing persecution in Eastern Europe. Among them was Isaac Benowitz (1872-1944), a successful businessman and philanthropist who supported various Jewish charities and organizations.
Other notable individuals with the Benowitz surname include David Benowitz (1937-2021), an American criminal defense attorney and legal scholar, and Sarah Benowitz (1921-2005), a Polish-born artist and sculptor who became renowned for her abstract works.
Demographics
Among Census respondents with the surname Benowitz, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (2.7%) and Asian/Pacific Islander (2.1%).
The bar chart below shows how Benowitz 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 Benowitz 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.
