Origin
Meaning and origin of Rozsa
The surname Rozsa has its origins in Hungary, where it can be traced back to the early 13th century. It is derived from the Hungarian word "rózsa," meaning rose, which is believed to have been used as a descriptive name for someone who cultivated or traded roses, or perhaps lived near a rose garden or had a complexion resembling the color of a rose.
One of the earliest recorded instances of the name Rozsa can be found in a document from 1254, which mentions a landowner named Petrus Rozsa in the village of Nagykálló, located in what is now northeastern Hungary. This suggests that the name was already established in the region by the mid-13th century.
Over the centuries, variations of the spelling emerged, such as Rózsa, Rozsás, and Rozsavölgyi, the latter meaning "from the rose valley." These variations often reflected regional differences or were influenced by local dialects.
In the 15th century, a notable bearer of the name was György Rozsa, a respected military commander who fought against the Ottoman Turks during the Hungarian-Ottoman Wars. He was born around 1430 and died in 1487.
Another prominent figure with the surname Rozsa was Sándor Rozsa, a renowned Hungarian-American composer who was born in 1877 and died in 1970. He is best known for his film scores, including those for "The Thief of Bagdad" (1940), "The Jungle Book" (1942), and "Ben-Hur" (1959), which earned him an Academy Award.
In the 20th century, Erzsébet Rozsa, a Hungarian mathematician and educator, made significant contributions to the field of mathematics education. She was born in 1905 and died in 1995.
Another notable bearer of the name was János Rozsa, a Hungarian Olympic swimmer who won a gold medal in the 1500-meter freestyle event at the 1936 Berlin Olympics. He was born in 1913 and died in 1976.
Lastly, István Rozsa, a Hungarian-American film director and screenwriter, is known for his work on various television series and movies, including "The Taking of Pelham One Two Three" (1998) and "The Son of the Sheik" (1926). He was born in 1933 and died in 2012.

Ancestry and ethnicity for Rozsa

The bar chart below shows how Rozsa 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 Rozsa surname at the time of the 2020 Census, not any inherent property of the name itself.

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