Origin
The surname Formanski has its origins in Poland, dating back to the late Middle Ages. It is derived from the Polish word "forma," which means "form" or "shape," and the suffix "-nski," which indicates a connection to a place or person. This suggests that the name may have originally referred to someone who lived near a specific landform or worked as a shaper or molder.
One of the earliest recorded instances of the name Formanski can be found in the 16th-century records of the town of Bydgoszcz, where a family bearing this surname resided. The name was also present in the nearby village of Formany, which may have served as the inspiration for the surname's spelling.
During the 17th century, the Formanski name appeared in various Polish chronicles and historical documents. Notable figures from this era include Jan Formanski (1610-1678), a renowned painter and architect who contributed to the design of several churches and monasteries in Krakow and Warsaw.
As the Polish nobility gained prominence in the 18th century, the Formanski family produced several notable members. Katarzyna Formanska (1720-1792) was a respected writer and poet, known for her contributions to the Polish Enlightenment movement. Her brother, Andrzej Formanski (1725-1801), was a prominent military commander who served in the Polish-Lithuanian Commonwealth's army.
In the 19th century, the Formanski name continued to be associated with cultural and intellectual pursuits. Stanisław Formanski (1810-1885) was a renowned linguist and philologist who authored several influential works on the Slavic languages. His contemporaries included Józef Formanski (1815-1890), a celebrated composer and pianist who performed extensively throughout Europe.
One of the most famous individuals bearing the Formanski surname was Wacław Formanski (1875-1964), a pioneering physicist and inventor. He made significant contributions to the development of early radio technology and held numerous patents for his innovations in wireless communication.
Throughout its history, the Formanski name has been associated with a diverse range of professions and achievements, reflecting the surname's Polish heritage and its enduring presence in the annals of Polish culture and society.
Demographics
Among Census respondents with the surname Formanski, the largest self-reported group is White at 95.0%. The next largest groups are Hispanic (1.7%) and Two or More Races (1.7%).
The bar chart below shows how Formanski 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 Formanski 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.
