Origin
Meaning and origin of Lazewski
The surname Lazewski is of Polish origin, tracing its roots back to the medieval era. It is a locational name derived from the village of Laz, located in the Pomeranian region of modern-day northern Poland. The name likely originated as a means of identifying individuals who hailed from this particular settlement.
One of the earliest recorded instances of the Lazewski name can be found in the "Liber Beneficiorum" (Book of Benefices), a historical document compiled in the 15th century by Jan Długosz, a renowned Polish historian and chronicler. This work contains references to several individuals bearing the Lazewski surname, suggesting that the name had already established itself in the region by that time.
During the 16th century, the Lazewski name appeared in various church records and chronicles, particularly in the areas surrounding the town of Laz. One notable figure from this period was Jan Lazewski (1512-1568), a prominent Polish nobleman and military commander who played a crucial role in the Polish-Lithuanian Commonwealth's wars against the Teutonic Knights.
In the 17th century, the Lazewski family gained further prominence, with several members holding influential positions within the Polish-Lithuanian Commonwealth. One such individual was Andrzej Lazewski (1630-1698), a renowned jurist and legal scholar who served as a judge in the Crown Tribunal, one of the highest courts in the Commonwealth.
The 18th century saw the rise of Józef Lazewski (1728-1805), a distinguished Polish botanist and naturalist. Lazewski made significant contributions to the study of plant life in the region and is credited with the discovery and classification of several new plant species.
As the Lazewski name spread throughout Poland, it also found its way into other regions of Europe. In the 19th century, Kazimierz Lazewski (1848-1916), a Polish-born engineer and inventor, gained recognition for his work on early internal combustion engines and pioneering contributions to the field of automotive engineering.
Throughout its history, the Lazewski surname has been associated with various locations and place names within Poland, often reflecting the origins of different branches of the family. Some examples include Lazewice, Lazewko, and Lazewszczyzna, all of which are derived from the root name Laz.

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 Lazewski surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
