Origin
Meaning and origin of Sicko
The surname "SICKO" is of Polish origin, dating back to the 16th century. It is believed to have originated in the region of Silesia, which was then part of the Kingdom of Poland. The name is derived from the Polish word "siczka," meaning "chaffed straw" or "chaff."
The earliest recorded instance of the name appears in a 1562 tax register from the town of Opole, where a certain Jan Sicko is listed as a landowner. This suggests that the name may have initially referred to someone involved in agriculture or farming, perhaps someone who worked with straw or chaff.
In the 17th century, the name is found in various church records and legal documents from the Silesian region. Notable bearers of the name during this time include Jakub Sicko (1621-1689), a prominent merchant and landowner from Wrocław, and Katarzyna Sicko (1654-1712), a respected midwife in the town of Opole.
As the Silesian region changed hands between Poland, Prussia, and Austria over the centuries, the name spread to other parts of Central Europe. In the 18th century, there are records of the Sicko family in the Czech lands, with Jan Sicko (1736-1801) being a notable figure, serving as a magistrate in the city of Brno.
The 19th century saw the name appearing in various parts of the Austro-Hungarian Empire, with several individuals bearing the name serving in the imperial military. One such individual was Jozef Sicko (1832-1901), a decorated officer in the Austrian Army who fought in the Austro-Prussian War of 1866.
As Poles and other Slavic peoples immigrated to the United States in the late 19th and early 20th centuries, the name Sicko was brought to America. One notable American bearer of the name was Stanislaw Sicko (1887-1963), a Polish-born artist and sculptor who lived and worked in Chicago.
Other notable individuals with the surname "SICKO" include Wladyslaw Sicko (1905-1981), a Polish engineer and academic who made significant contributions to the field of mechanics, and Maria Sicko (1926-2012), a Polish writer and poet who won several literary awards for her work.
Demographics
Ancestry and ethnicity for Sicko

The bar chart below shows how Sicko 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 Sicko 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 Sicko (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.
