Origin
The surname Lewalski originated in Poland, with roots dating back to the Middle Ages. It likely derived from the Polish word "lewo," meaning "left," suggesting a connection to a location or feature situated on the left side of a specific area or landmark.
The earliest known records of the Lewalski name can be traced back to the 14th century, appearing in various historical documents and manuscripts from regions within present-day Poland. One notable example is the mention of a Lewalski family in the archives of the city of Krakow, dating back to the late 1300s.
During the 15th and 16th centuries, the Lewalski name became more widespread throughout Poland, with several variations in spelling, including Lewalsky, Levallski, and Lewallsky. These variations often reflected regional dialects and linguistic influences within different Polish regions.
One of the earliest documented individuals bearing the Lewalski surname was Jan Lewalski, a prominent merchant and landowner who lived in the city of Poznan in the late 15th century. Records indicate that he played a significant role in the city's trade and economic affairs during that period.
Another notable figure was Katarzyna Lewalska, a renowned scholar and educator who lived in Krakow during the 16th century. She was widely respected for her contributions to the field of education and her efforts in promoting literacy among women.
In the 17th century, the Lewalski name gained further prominence with the rise of Jakub Lewalski, a skilled military strategist who served in the Polish army during the Swedish-Polish wars. His tactical expertise and leadership were instrumental in several decisive battles against Swedish forces.
During the 18th and 19th centuries, the Lewalski surname continued to spread throughout various regions of Poland, with some families emigrating to other parts of Europe and beyond. Notable individuals from this period include Maria Lewalska, a celebrated author and poet who lived in Warsaw in the early 19th century, and Franciszek Lewalski, a prominent architect responsible for designing several iconic buildings in the city of Lodz in the mid-1800s.
As the Lewalski name traveled across borders, it has undergone slight variations in spelling and pronunciation, reflecting the linguistic influences of different cultures and regions. However, its Polish origins and historical significance remain deeply rooted in its etymology and legacy.
Demographics
Among Census respondents with the surname Lewalski, the largest self-reported group is White at 92.4%. The next largest groups are Hispanic (3.8%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Lewalski 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 Lewalski 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.
