Origin
Meaning and origin of Hasek
The surname Hasek is of Czech origin, with its roots tracing back to the 14th century in the regions of Bohemia and Moravia, which are now part of the modern-day Czech Republic. The name is believed to derive from the Czech word "hasák," which translates to "extinguisher" or "fireman." This suggests that the name's earliest bearers may have been associated with fire-related professions or duties.
One of the earliest recorded instances of the name Hasek can be found in the Liber Vetustissimus Antiquae Civitatis Pragensis, a historical manuscript dating back to the late 14th century, which contains records of citizens and landowners in Prague. The name appears with various spellings, such as "Hassek," "Hasek," and "Hassak," reflecting the linguistic evolution and regional variations in pronunciation.
During the 16th and 17th centuries, the name Hasek can be found in various historical documents, including parish records and land registries, particularly in the regions of Bohemia and Moravia. One notable individual bearing this surname was Jan Hasek (1541-1599), a Czech Protestant theologian and writer who played a significant role in the translation of the Bible into the Czech language.
In the 19th century, the name Hasek gained prominence with the birth of Jaroslav Hasek (1883-1923), a renowned Czech writer and satirist, best known for his unfinished satirical novel "The Good Soldier Švejk." Hasek's literary works have become iconic in Czech literature and have been widely translated and celebrated internationally.
Another notable figure with the surname Hasek was Dominik Hasek (born 1965), a legendary Czech ice hockey goaltender who played in the National Hockey League (NHL) and is considered one of the greatest goaltenders in the history of the sport. He won two Olympic gold medals with the Czech national team and was inducted into the Hockey Hall of Fame in 2014.
Other historical figures bearing the name Hasek include Vaclav Hasek (1919-1983), a Czech sculptor and artist known for his monumental public artworks, and Tomas Hasek (born 1965), a Czech politician and member of the European Parliament.
While the surname Hasek has its roots in Czech history and culture, it has since spread to other parts of the world through migration and diaspora, with bearers of this name found in various countries, particularly in Europe and North America.

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 Hasek 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.
