Origin
The surname Jadlowski originates from Poland and can be traced back to the 16th century. It is derived from the Polish word "jadło," which means "food" or "meal," and the suffix "-owski," indicating a place of origin or association. This suggests that the name may have been originally associated with someone who worked in the food industry or lived near a location related to food production.
One of the earliest recorded instances of the Jadlowski surname can be found in a 1567 document from the town of Krakow, where a certain Maciej Jadlowski is mentioned as a baker. This provides evidence that the name was already in use during the Renaissance period in Poland.
In the 17th century, the Jadlowski name appears in several church records from the city of Poznan, indicating that families bearing this surname were present in different regions of Poland at that time. One notable individual from this era was Jan Jadlowski (1620-1689), a renowned herbalist and apothecary who published several works on medicinal plants and their applications.
During the 18th century, the Jadlowski surname gained prominence in the nobility of the Polish-Lithuanian Commonwealth. Records show that a family of this name owned a estate near the town of Lublin, and several members held positions of authority within the local government and military.
In the 19th century, the Jadlowski name continued to be associated with various professions and social classes in Poland. For instance, Stanislaw Jadlowski (1810-1887) was a respected architect who designed several notable buildings in Warsaw, while Waclaw Jadlowski (1838-1902) was a prominent lawyer and judge.
Another notable figure with this surname was Karolina Jadlowska (1855-1924), a Polish writer and activist who played a significant role in the women's rights movement in the late 19th and early 20th centuries.
While the Jadlowski name has its roots in Poland, it has also spread to other parts of the world through immigration and cultural exchange. However, it remains primarily associated with its Polish heritage and the long history of individuals bearing this surname in various walks of life throughout the centuries.

The bar chart below shows how Jadlowski 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 Jadlowski 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.
