Origin
The surname Swincicki originates from Poland and is believed to have emerged in the late 15th century. It is derived from the Polish word "świńca," which means "swineherd" or "pig keeper." This suggests that the name was initially associated with individuals who worked as swineherds or were involved in the pig-keeping trade.
Early records indicate that the name was concentrated in the regions of Wielkopolska and Mazowsze, areas known for their agricultural traditions and livestock farming. The earliest documented instances of the Swincicki surname can be traced back to the 16th century, appearing in parish records and land ownership documents.
One of the earliest known bearers of the Swincicki name was Jan Swincicki, a landowner and farmer who lived in the village of Swincice, near Poznań, in the late 16th century. Another notable figure was Maciej Swincicki, a renowned pig breeder and farmer who lived in the town of Płock in the early 17th century.
During the 17th and 18th centuries, the Swincicki surname appeared in various historical records, including tax registers, court documents, and military records. It is worth noting that the spelling of the name may have varied slightly due to regional dialects and transcription practices.
In the 19th century, Szymon Swincicki (1810-1882) was a prominent landowner and philanthropist from the Lublin region. He was known for his contributions to local education and social initiatives. Another notable bearer of the name was Stanisław Swincicki (1856-1931), a respected agriculturalist and author who wrote extensively on modern farming practices.
Other individuals with the Swincicki surname who made significant contributions include Józef Swincicki (1875-1948), a renowned veterinarian and researcher in animal husbandry, and Wanda Swincicka (1892-1976), a celebrated painter and artist who was part of the Polish avant-garde movement in the early 20th century.

Demographics

The bar chart below shows how Swincicki 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 Swincicki 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.
