Origin
Meaning and origin of Stasak
The surname Stasak has its origins in Western Europe, with the earliest records pointing to regions in what is now modern-day Germany and Poland. The name is believed to have derived from an Old Slavic word meaning "aged" or "old," potentially referring to an ancestor's advanced age or a place name associated with an older settlement.
One of the earliest documented references to the name can be found in a 14th-century manuscript from Silesia, where a person named Stasak was mentioned as a landowner in the village of Woynitz. This suggests that the name was already established in the region during that period.
In the 16th century, records show a Hans Stasak who was a prominent merchant in the city of Danzig (now Gdansk, Poland). His successful trade ventures and influence within the local guilds indicate that the Stasak name had gained recognition and status in the area.
Another notable figure was Johann Stasak, a German scholar and theologian born in 1612 in the town of Breslau (now Wroclaw, Poland). He authored several works on religious philosophy and served as a professor at the University of Leipzig.
Moving into the 18th century, there are records of a family with the Stasak surname residing in the village of Neustadt (now Prudnik, Poland), where they were landowners and farmers. This suggests that the name had spread to various regions and was associated with both urban and rural communities.
In the early 19th century, a notable individual named Friedrich Stasak (1792-1867) gained recognition as a respected architect and civil engineer in Berlin. He was responsible for designing several prominent buildings and infrastructure projects in the city.
While the Stasak surname has its roots in Central and Eastern Europe, it has since spread to other parts of the world through migration and diaspora. However, its earliest and most significant historical presence can be traced back to the regions of Germany and Poland, where it has been documented for centuries.

The bar chart below shows how Stasak 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 Stasak 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.
