Origin
The surname RADOSH has its origins in the Slavic regions of Eastern Europe, specifically in the areas that are now parts of Poland, Ukraine, and Russia. It is believed to have emerged sometime in the late medieval period, around the 13th or 14th century.
One theory suggests that the name RADOSH is derived from the Old Slavic word "rad," which means "joy" or "happiness." This could indicate that the name was initially given to someone with a cheerful or joyful disposition. Alternatively, it may have been a name adopted by someone who lived near a place associated with joy or celebration.
Another possible origin of the name RADOSH is that it is a patronymic form, meaning it was derived from a given name such as Radoslav or Radimir. These names combine the Slavic root "rad" with other elements like "slav" (glory) or "mir" (peace), suggesting the name may have been associated with concepts of joy, glory, or peace.
Some of the earliest recorded instances of the surname RADOSH can be found in historical documents from the region. For example, there are mentions of individuals with this surname in Polish parish records dating back to the 16th century. One notable figure was Jan Radosh, a Polish nobleman born in the late 1500s who served as a military commander during the Polish-Swedish wars.
In the 17th century, there are records of a Radosh family residing in the town of Lviv, which was then part of the Polish-Lithuanian Commonwealth (now in modern-day Ukraine). One member of this family, Teodor Radosh, was a merchant and landowner who lived from 1620 to 1688.
As the name spread across Eastern Europe, variations in spelling and pronunciation emerged. For instance, in Russian records, the name is sometimes spelled as Radoshev or Radoshevich, indicating a patronymic form.
Another notable bearer of the surname RADOSH was Mikhail Radosh, a Russian academic and writer who lived from 1856 to 1919. He was a professor of Slavic literature and authored several works on the subject.
In the 20th century, one of the most prominent individuals with the surname RADOSH was the American author and historian Ronald Radosh, who was born in 1937. He is known for his works on Cold War history and the American left-wing political movements.
While not an exhaustive list, these examples illustrate the long-standing presence and historical significance of the surname RADOSH in various parts of Eastern Europe and beyond.
Demographics
Among Census respondents with the surname Radosh, the largest self-reported group is White at 99.0%. The next largest groups are Two or More Races (1.0%).
The bar chart below shows how Radosh 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 Radosh 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.
