Origin
The surname Zavulunov has its origins in the regions historically associated with the Jewish diaspora, particularly in Eastern Europe. The name is thought to be patronymic, derived from the Hebrew name Zebulun (Zevulun in Hebrew), one of the twelve tribes of Israel as described in the Bible. The switch from 'Zebulun' or 'Zevulun' to 'Zavulun' likely aligns with the phonetic and linguistic shifts that occur across different languages and cultures over time.
The earliest documented appearances of surnames similar to Zavulunov can be traced back to the Jewish Pale of Settlement in the Russian Empire, which spanned from the late 18th century to the early 20th century. This was a region where Jews were allowed permanent residency, including areas in modern-day Poland, Lithuania, Ukraine, and Belarus. The name Zavulunov is relatively rare and can be linked to the Hebrew biblical heritage carried by Jewish communities in these regions.
Historically, Jewish surnames were often patronymic, meaning they were derived from the given name of a male ancestor. The use of '-ov' as a suffix is a common Slavic patronymic indicator meaning 'son of'. This suggests that the surname Zavulunov means 'son of Zebulun' or 'son of Zevulun', tying the bearers of this name to an ancestral worship of Zebulun, one of Jacob's sons as per the Hebrew Bible.
One of the earliest recorded instances of the surname Zavulunov appears in early 19th-century records in Ukraine, found in local documents referring to tax records and census data. In these records, Avram Zavulunov, born in 1802, is noted as a merchant in Odessa, a prominent port city that attracted many Jewish families during this period. The documentation of this surname in the Odessa records highlights the migration patterns within the Jewish communities as they sought economic opportunities.
Another historical figure with this surname is Moishe Zavulunov, a scholar and rabbi born in 1845 in the region of Bessarabia, which is part of modern-day Moldova. Moishe was known for his religious teachings and published several works on Jewish law and customs, contributing to the cultural and religious life of his community until his death in 1911.
Sofya Zavulunov, a social activist born in 1878 in Vilnius (then part of the Russian Empire, now the capital of Lithuania), played a significant role in advocating for Jewish rights and education, particularly focusing on women's access to learning. Her activism and community work during the early 20th century paved the way for subsequent Jewish educational reforms.
In the early 20th century, as upheavals and migrations increased, the name Zavulunov appeared in new geographies. An example is Yakov Zavulunov, an immigrant to the United States, who arrived at Ellis Island in 1913. Yakov, born in 1890 in Kyiv, Ukraine, became a notable figure in the New York labor movements, fighting for worker's rights and fair conditions until his death in 1957.
Another noteworthy figure is Leonid Zavulunov, a Soviet physicist born in 1931, who made significant contributions to the field of nuclear physics during the Cold War era. His research and academic work were well-regarded within scientific communities until his retirement and subsequent passing in 2002.
Throughout history, the surname Zavulunov represents a rich tapestry of Jewish heritage woven through various regions of Eastern Europe and beyond. Its bearers have contributed to religious scholarship, social activism, scientific research, and economic developments, illustrating a diverse legacy attached to this patronymic name.

The bar chart below shows how Zavulunov 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 Zavulunov 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.
