Origin
Meaning and origin of Hazen
The surname HAZEN has its origins in England, first appearing in records during the 12th century. It is believed to have derived from the Old English word "hæzen," which means "hazel tree." This suggests that the name may have been initially given as a descriptive name to someone who lived near or worked with hazel trees.
One of the earliest recorded instances of the name can be found in the Pipe Rolls of Lincolnshire from 1195, which mentions a person named Robert de Hezene. This spelling variation, "Hezene," further supports the connection to the Old English word "hæzen."
In the 13th century, the name appears in the Hundred Rolls of Oxfordshire as "Hasen," indicating the variant spellings that were common during that time. This record, dated 1273, mentions a William Hasen.
The Hazen surname has been associated with several notable individuals throughout history. One such person was Sir Edward Hazen (1570-1638), an English politician who served as a Member of Parliament for Leicestershire in the early 17th century.
Another notable figure was Moses Hazen (1733-1803), an American military officer who fought in the French and Indian War and the American Revolutionary War. He was born in Haverhill, Massachusetts, and played a crucial role in several battles during the Revolutionary War.
In the literary world, David Hazen (1910-2003), an American poet and professor, gained recognition for his works, including the book "The Rites and Ceremonies" published in 1968.
The Hazen surname has also been associated with various place names, such as Hazen, Arkansas, and Hazen, North Dakota, both named after William B. Hazen, a prominent railroad official in the late 19th century.
Another noteworthy individual was Robert Hazen (1835-1918), an American industrialist and philanthropist who founded the Hazen Paper Company in Holyoke, Massachusetts, in the late 19th century.

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

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 Hazen (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.
