Origin
The surname Jeziorowski originated in Poland, with earliest records dating back to the 13th century. It is derived from the Polish word "jezioro" meaning "lake" and the suffix "-owski" denoting a place of origin. This suggests that the name likely referred to someone who lived near or came from a place with a lake.
The name appears to have roots in the Kuyavian-Pomeranian region of central Poland, where many villages and towns were named after nearby bodies of water. Some of the earliest known spellings include Jeziorowsky, Jeziorovsky, and Ieziorowsky.
Historical references to the name Jeziorowski can be found in various Polish records and manuscripts from the medieval period onwards. One notable example is a land deed from 1412 mentioning a certain Jan Jeziorowski, a landowner in the village of Jeziorzany.
In the 16th century, there are records of a Maciej Jeziorowski, a nobleman and military commander who fought in the Polish-Muscovite War of 1577-1582. Another early bearer of the name was Marcin Jeziorowski, a scholar and rector of the Jagiellonian University in Krakow, who lived from 1590 to 1654.
During the 17th century, the name Jeziorowski gained prominence with the rise of the Jeziorowski family, a wealthy and influential noble clan from the Bydgoszcz region. One of their most notable members was Jan Stanisław Jeziorowski (1670-1736), a politician and diplomat who served as the Grand Marshal of the Crown.
Another significant figure was Józef Jeziorowski (1724-1794), a military officer and participant in the Kościuszko Uprising against Russian rule. He was captured and executed by the Russians in 1794.
In more recent times, notable individuals with the surname Jeziorowski include Stanisław Jeziorowski (1871-1951), a Polish painter and art critic, and Tadeusz Jeziorowski (1915-1992), a Polish actor and film director.
Demographics
Among Census respondents with the surname Jeziorowski, the largest self-reported group is White at 88.5%. The next largest groups are Hispanic (6.7%) and Two or More Races (3.8%).
The bar chart below shows how Jeziorowski 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 Jeziorowski 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.
