Origin
Meaning and origin of Haase
The surname Haase originated in Germany, where it first appeared in the 14th century. It is derived from the Low German word "Hase," meaning "hare" or "rabbit." This nickname likely referred to someone who was known for their quickness or agility, traits associated with hares.
The earliest recorded instance of the name Haase can be found in the records of the city of Hamburg, dating back to the year 1330. The name was also present in other northern German regions, such as Lower Saxony and Mecklenburg.
Over time, the name evolved to include various spellings, including Hase, Haasse, and Haas. These variations were likely influenced by regional dialects and the way the name was pronounced in different areas.
One notable historical figure bearing the name Haase was Hans Haase, a German theologian and reformer who lived from 1409 to 1479. He played a significant role in the Reformation movement and was a close associate of Martin Luther.
Another prominent individual with the surname was Wilhelm Haase, a German classical philologist born in 1794. He made significant contributions to the study of ancient Greek and Roman literature and is known for his work on the texts of Seneca and Pliny the Younger.
In the 19th century, Karl Haase, a German jurist and politician, served as a member of the Prussian House of Representatives and was involved in the drafting of the German Civil Code.
The name Haase also has connections to place names in Germany. For example, the town of Haselünne in Lower Saxony is believed to have derived its name from the Old Saxon word "Hasala," meaning "hazel grove" or "place of hares."
Other notable individuals with the surname Haase include Hugo Haase, a German politician and co-founder of the Independent Social Democratic Party of Germany, and Carl Haase, a German chess master and writer on chess theory in the late 19th century.

The bar chart below shows how Haase 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 Haase surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Haase (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
