Origin
Meaning and origin of Hannus
The surname Hannus originated in Finland, dating back to the 16th century. It is believed to be derived from the Finnish word "hanhi," which means "goose." This suggests that the name may have been initially associated with people who raised or traded geese.
The earliest recorded instances of the name Hannus can be found in Finnish parish records from the late 16th and early 17th centuries. For example, a man named Hannus Antinpoika was mentioned in the records of the Lappeenranta parish in 1596.
In the 17th century, the name Hannus was particularly prevalent in the regions of Savonia and Karelia, which were part of the Swedish Empire at the time. It is likely that the name spread across these areas due to migration and trade.
One notable figure with the surname Hannus was Pekka Hannus, a Finnish farmer and soldier who fought in the Finnish War of 1808-1809 against Russia. He was born in 1782 in Kangasniemi and became known for his bravery and leadership during the conflict.
Another individual of historical significance was Juho Hannus, a Finnish politician and member of the Finnish Parliament in the early 20th century. Juho Hannus, born in 1866 in Joroinen, played a role in the Finnish independence movement and advocated for workers' rights.
In the 19th century, the name Hannus appeared in various Finnish literature and historical records. For instance, the Finnish author Zacharias Topelius mentioned a character named Hannus in his novel "The Surgeon's Stories" (Fältskärns berättelser), published in 1853.
The surname Hannus can also be found in some place names in Finland, such as Hannuskylä (Hannus Village) in the municipality of Tohmajärvi, and Hannusjärvi (Hannus Lake) in the region of Kainuu.
Other notable individuals with the surname Hannus include Kaarlo Hannus, a Finnish athlete who competed in the 1912 Summer Olympics in Stockholm, and Svante Hannus, a Finnish businessman and industrialist who lived in the late 19th and early 20th centuries.

Ancestry and ethnicity for Hannus

The bar chart below shows how Hannus 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 Hannus 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.
