Origin
The surname Sikorski is of Polish origin, derived from the word "sikora," which means "titmouse" in Polish. This surname likely originated in the medieval period, when surnames were commonly derived from nicknames related to physical characteristics, occupations, or personal traits.
The name Sikorski is believed to have originated in the historical region of Greater Poland, located in west-central Poland. This region was once a part of the Piast dynasty, one of the earliest ruling dynasties of Poland, which dates back to the 10th century.
One of the earliest recorded instances of the name Sikorski can be found in the Księga Henrykowska, a 14th-century manuscript containing records of land ownership and transactions in the Silesian region of Poland. This document mentions a certain "Nicolaus Sikorski" from the village of Strzelin.
In the 15th century, the name Sikorski appeared in various records and documents from the city of Krakow, which was then the capital of the Polish Kingdom. One notable individual from this period was Jan Sikorski, a merchant and city councilor who lived in Krakow during the reign of King Casimir IV Jagiellon (1427-1492).
During the Renaissance period, the Sikorski family produced several notable figures, including Mikołaj Sikorski (1548-1610), a Polish poet and translator who is considered one of the pioneers of Polish Renaissance literature.
Another prominent individual with the surname Sikorski was Józef Sikorski (1813-1896), a Polish composer and conductor who was instrumental in the development of Polish national opera in the 19th century. His compositions, such as the opera "Halka," are still performed today.
In the 20th century, one of the most famous individuals with the surname Sikorski was Władysław Sikorski (1881-1943), a Polish military leader and statesman who served as Prime Minister of the Polish government-in-exile during World War II. He played a crucial role in organizing the Polish resistance against the Nazi occupation.
It is worth noting that the surname Sikorski has also been associated with various place names throughout Poland, such as the village of Sikorskie in the Kuyavian-Pomeranian Voivodeship, and the town of Sikorz in the Greater Poland Voivodeship.
Demographics
Among Census respondents with the surname Sikorski, the largest self-reported group is White at 93.0%. The next largest groups are Hispanic (3.0%) and Two or More Races (2.4%).
The bar chart below shows how Sikorski 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 Sikorski 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.
