Origin
The surname Osofsky originates from Eastern Europe, particularly from regions that are now part of modern-day Ukraine and Belarus. It is believed to have emerged in the late 18th or early 19th century, derived from the Yiddish or Russian word "osof," which means "collector" or "gatherer."
The earliest known record of the name Osofsky can be traced back to the town of Zhytomyr, located in northern Ukraine, where a Jewish family bearing this surname was documented in the late 1700s. It is possible that the name may have been adopted by individuals whose occupation involved collecting or gathering goods, materials, or taxes.
In the early 19th century, the Osofsky surname appeared in various records and manuscripts throughout the Russian Empire, particularly in areas with significant Jewish populations. One notable mention is found in the memoirs of a Russian nobleman, where he recounted his interactions with a merchant named Yakov Osofsky in the city of Odesa around 1820.
Among the earliest recorded individuals with the surname Osofsky was Shmuel Osofsky, born in the town of Berdychiv (now in Ukraine) in 1791. He was a prominent scholar and Rabbi who authored several works on Jewish law and philosophy.
Another notable figure was Lev Osofsky (1837-1917), a Russian-born painter and art teacher who spent most of his career in St. Petersburg, where he gained recognition for his landscapes and portraits.
In the late 19th century, Esther Osofsky (1862-1942) became known as one of the first female physicians in the Russian Empire, practicing in the city of Kharkiv (now in Ukraine) and advocating for women's rights and education.
As the Osofsky family spread across Eastern Europe, variations in spelling and pronunciation emerged, such as Osofski, Osofski, and Osovski. Some members of the family also adopted the surname Osofskyy or Osofskiy, reflecting the Russian or Ukrainian spelling.
One of the most famous individuals with the surname Osofsky was Mikhail Osofsky (1900-1976), a Soviet composer and conductor who contributed significantly to the development of Russian and Ukrainian classical music in the 20th century.
Throughout its history, the Osofsky surname has been associated with various professions, including merchants, scholars, artists, and professionals, reflecting the diverse backgrounds and experiences of those who bore this name.
Demographics
Among Census respondents with the surname Osofsky, the largest self-reported group is White at 94.1%. The next largest groups are Two or More Races (3.0%) and Hispanic (1.3%).
The bar chart below shows how Osofsky 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 Osofsky 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.
