Origin
Meaning and origin of Lebak
The surname "LEBAK" is believed to have originated in the Czech Republic, with its roots traced back to the 16th century. The name is thought to be derived from the Czech word "leb," which means "forehead" or "skull." It is possible that the name was initially given to someone with a distinctive forehead or head shape.
In the early records, the name appears with various spellings, such as "Lebak," "Lebáček," and "Lebačka." These variations were common in the past due to the inconsistencies in spelling and record-keeping practices.
One of the earliest known references to the name "LEBAK" can be found in the parish records of the village of Hostovice, located in the Bohemia region of the Czech Republic. The record dates back to 1587 and mentions a certain Jan Lebak, who was a local landowner.
Another notable figure bearing the surname "LEBAK" was Matěj Lebak (1586-1647), a prominent Czech theologian and author. He was born in the town of Žatec and wrote several influential works on religious topics during the Reformation period.
In the 18th century, the name "LEBAK" appears in the records of the city of Brno, which was then part of the Habsburg Monarchy. One of the earliest recorded individuals with this surname was Tomáš Lebak (1712-1778), a respected tradesman and merchant in the city.
As the name spread across Europe, it also found its way to other regions. In the late 19th century, there was a notable figure named Alois Lebak (1856-1921), who was a renowned architect from Bavaria, Germany. He was responsible for designing several prominent buildings in Munich and other cities in the region.
Another individual of note was Jan Lebak (1902-1979), a Czech-born American artist and sculptor. He immigrated to the United States in the 1920s and became known for his unique modernist style, with many of his works displayed in galleries and museums across the country.
While the surname "LEBAK" may not be among the most common surnames today, its origins can be traced back to the rich historical and cultural heritage of the Czech Republic, with influences from other parts of Europe over the centuries.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
