Origin
The surname Jaworski is of Polish origin, originating from the Slavic word "jawor" which means "maple tree." It is likely that the name was initially given as a descriptive surname to someone who lived near a maple grove or forest.
The earliest known record of the name Jaworski can be traced back to the 15th century, where it appears in historical documents from the Krakow region of Poland. Some variations of the spelling include Iavorski, Iavorsky, and Yavorskiy.
In the 16th century, there are records of a prominent Polish noble family using the Jaworski surname. This family owned land and estates in the Galicia region, which is now part of modern-day Ukraine and Poland.
One of the earliest recorded individuals with the Jaworski surname was Jan Jaworski (1535-1609), a Polish Catholic priest and theologian who served as the Bishop of Chelm from 1589 to 1609.
Another notable figure was Stanislaw Jaworski (1658-1724), a Polish mathematician and astronomer who made significant contributions to the field of celestial mechanics. He is best known for his work on the motion of planetary bodies and the calculation of eclipses.
In the 19th century, the Jaworski surname gained prominence with the birth of Wladyslaw Jaworski (1865-1924), a Polish pianist and composer who studied under renowned musicians such as Ignacy Jan Paderewski and Theodor Leschetizky.
During World War II, Franciszek Jaworski (1901-1944) was a Polish resistance fighter and member of the Armia Krajowa (Home Army). He was executed by the Nazis in 1944 for his role in the Polish Underground resistance movement.
Another notable figure was Leon Jaworski (1905-1982), an American lawyer and public servant who served as the Special Prosecutor during the Watergate scandal. He played a crucial role in the investigation that ultimately led to the resignation of President Richard Nixon.
Demographics
Among Census respondents with the surname Jaworski, the largest self-reported group is White at 93.7%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.1%).
The bar chart below shows how Jaworski 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 Jaworski 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.
