One of the earliest recorded instances of the name Jarosz can be found in the Akta Grodzkie records from the 15th century, which were official court documents from the Polish-Lithuanian Commonwealth. These records mention individuals with the surname Jarosz, indicating that the name was in use during that time period.
In the 16th century, the Jarosz surname appeared in the Metryka Koronna, a collection of official records from the Crown of the Kingdom of Poland. This suggests that the name had become more widespread and established during that era.
The Jarosz name has also been associated with various place names in Poland, such as the village of Jaroszów in the Lower Silesian Voivodeship. This may indicate that some individuals with the surname originated from or had connections to these locations.
One notable figure with the surname Jarosz was Andrzej Jarosz (1538-1599), a Polish nobleman and landowner who served as a voivode (governor) of the Lublin Voivodeship during the 16th century.
Another prominent individual was Józef Jarosz (1892-1964), a Polish painter and art educator who was known for his landscapes and genre scenes depicting rural life in Poland.
In the 18th century, Stanisław Jarosz (1718-1799) was a Polish historian and author who wrote several works on the history of Poland and the Polish-Lithuanian Commonwealth.
The 19th century saw the birth of Władysław Jarosz (1870-1936), a Polish politician and economist who served as a member of the Sejm (parliament) and held various positions in the government.
More recently, Ewa Jarosz (born 1950) is a Polish actress and singer who has appeared in numerous films and theatrical productions throughout her career.
These examples demonstrate the long-standing presence of the Jarosz surname in Poland and its connection to various historical figures from different walks of life.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Jarosz (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
