Origin
Meaning and origin of Radzinski
The surname Radzinski originated in Poland, with the earliest records dating back to the 16th century. It is believed to be derived from the Polish word "radzić," which means "to counsel" or "to advise." This suggests that the name may have initially referred to someone who provided wise counsel or advice within their community.
One of the earliest recorded references to the Radzinski name can be found in the historical records of the Polish town of Poznan, where a merchant named Jan Radzinski was mentioned in a document from 1562. This document detailed a trade agreement between local merchants and their counterparts from neighboring regions.
In the 17th century, the Radzinski name appeared in various church records and land registries across various regions of Poland, indicating that the family had established itself across different parts of the country. One notable example is the birth record of Katarzyna Radzinska, born in 1687 in the village of Grodek, near the city of Krakow.
The name Radzinski can also be traced back to the village of Radzinka, located in central Poland. It is possible that the name originated as a toponymic surname, referring to individuals who hailed from this particular village or its surrounding areas.
Among the notable individuals with the Radzinski surname throughout history is Stanisław Radzinski (1687-1752), a Polish nobleman and military commander who served in the army of King Augustus II the Strong. Another prominent figure was Józef Radzinski (1818-1892), a Polish writer and journalist who played an active role in the Polish independence movement during the 19th century.
In the 20th century, the name Radzinski gained recognition through the work of Elżbieta Radzinska (1916-1994), a renowned Polish historian and author who wrote extensively about the history of Poland and its monarchs. Additionally, Marek Radzinski (born 1974) is a former professional soccer player who represented the Polish national team and played for several clubs in Europe and North America.
While these are just a few examples, the Radzinski surname has a rich history that can be traced back to its Polish roots and has been carried by individuals from various walks of life throughout the centuries.

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 Radzinski surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
