Origin
Meaning and origin of Hasenbeck
The surname HASENBECK originated in Germany. It is believed to have first appeared in the 14th century in the region of Lower Saxony. The name is derived from the German words "Hase" meaning "hare" and "Beck" meaning "brook" or "stream". This suggests that the name likely referred to someone who lived near a brook where hares were commonly found.
One of the earliest recorded instances of the HASENBECK name can be found in a document from the town of Hildesheim, dated 1387. This document mentions a "Johannes Hasenbeck" who was a local landowner. Other early mentions of the name appear in church records and tax rolls from villages in the surrounding areas of Lower Saxony during the 15th and 16th centuries.
In the 17th century, the HASENBECK name began to spread to other parts of Germany. A notable early bearer of the name was Johann Friedrich Hasenbeck (1642-1701), a Lutheran theologian and author from Halberstadt. Another prominent figure was Gottfried Hasenbeck (1668-1729), a jurist and legal scholar who served as a judge in Wolfenbüttel.
As the name dispersed further, it underwent various spelling variations such as "Hasenbek", "Haasenbeck", and "Haasenbek". In the 19th century, the HASENBECK surname can be found in records from cities like Berlin and Hamburg, indicating that bearers of the name had migrated to urban centers.
One notable 19th century individual with the HASENBECK name was Karl Hasenbeck (1834-1909), a German architect who designed several notable buildings in Berlin, including the Reichspatentamt (Imperial Patent Office). Another was Friedrich Wilhelm Hasenbeck (1837-1916), a German-American civil engineer who worked on the construction of several railroads in the United States.
In the 20th century, a prominent HASENBECK was Walther Hasenbeck (1913-1988), a German politician who served as a member of the Bundestag (federal parliament) for the Social Democratic Party of Germany from 1957 to 1976.

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 Hasenbeck 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.
