Origin
Meaning and origin of Radom
The surname RADOM is of Polish origin, tracing its roots back to the medieval period. It is believed to have originated from the city of Radom, located in central Poland, which itself derives its name from the Old Polish word "radomy," meaning "happy" or "joyful."
One of the earliest recorded instances of the RADOM surname can be found in the Akta Grodzkie, a collection of Polish court records from the 15th and 16th centuries. In these documents, the name is spelled in various ways, such as "Radomski," "Radomczyk," and "Radomianin," reflecting the regional variations in pronunciation and spelling at the time.
During the Renaissance period, the RADOM surname gained prominence with the rise of the noble Radom family, who held significant influence and landholdings in the region. Prominent members of this family included Jan Radom (1498-1572), a renowned military commander who fought in the wars against the Teutonic Knights, and Katarzyna Radom (1532-1610), a philanthropist and patron of the arts.
In the 17th century, the RADOM surname spread beyond its original locale as individuals migrated to other parts of Poland and neighboring countries. One notable figure from this era was Michał Radom (1625-1692), a Jesuit priest and theologian who authored several influential works on philosophy and theology.
The 19th century saw the emergence of several notable individuals bearing the RADOM surname, including Józef Radom (1801-1876), a prominent architect and urban planner who designed many iconic buildings in Warsaw, and Maria Radom (1845-1919), a pioneering educator and advocate for women's rights.
As Poland underwent significant political and social changes in the 20th century, the RADOM surname continued to be represented by accomplished individuals. Among them were Stanisław Radom (1910-1985), a distinguished physicist and academic who made significant contributions to the field of theoretical physics, and Janina Radom (1923-2012), a celebrated writer and poet whose works explored themes of identity, memory, and the human condition.
Throughout its history, the RADOM surname has been borne by individuals from various walks of life, including artists, scholars, politicians, and entrepreneurs, reflecting the diverse heritage and contributions of those who have carried this name across generations.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
