Origin
The surname Halvorsen originated in Norway, with its earliest recorded use dating back to the 11th century. The name is a patronymic, derived from the Old Norse name Hallvard, which is a compound of the elements "hallr" meaning "rock" and "varðr" meaning "guardian." It essentially translates to "rock guardian." The name Hallvard was a popular name among the Vikings, and it is believed that Halvorsen was originally used to indicate a person who was the son of Hallvard.
The Halvorsen name can be found in several historical records from Norway, including the Landnåmabók, a medieval Icelandic manuscript that chronicles the settlement of Iceland. One of the earliest known individuals with the name was Hallvard Halvorsen, a Norwegian chieftain who lived in the late 10th century.
In the 13th century, a man named Halvor Halvorsen is mentioned in the Diplomatarium Norvegicum, a collection of medieval Norwegian diplomas and charters. He was a landowner and is recorded as having donated land to the Church.
The name Halvorsen has also been associated with various place names in Norway, such as Halvorsbygd and Halvorshagen, which are believed to have derived their names from early settlers with the Halvorsen surname.
One notable individual with the Halvorsen name was Halvor Halvorsen (1887-1972), a Norwegian journalist and writer who worked for several prominent Norwegian newspapers and published several books on Norwegian history and culture.
Another famous Halvorsen was Olav Halvorsen (1902-1978), a Norwegian composer and conductor who is best known for his orchestral works and concertos. He served as the principal conductor of the Bergen Philharmonic Orchestra from 1950 to 1963.
In the field of sports, Odd Halvorsen (1926-2004) was a Norwegian football player and manager who played for the Norwegian national team and later managed several Norwegian clubs, including Rosenborg BK.
Elsa Halvorsen (1894-1973) was a Norwegian actress and singer who performed in numerous plays and musicals throughout her career, and was considered one of the leading actresses of her time in Norway.
Lastly, Bjørn Halvorsen (1943-2022) was a Norwegian politician who served as a member of the Storting, the Norwegian parliament, representing the Conservative Party from 1981 to 2005.
Demographics
Among Census respondents with the surname Halvorsen, the largest self-reported group is White at 90.5%. The next largest groups are Hispanic (4.4%) and Two or More Races (3.1%).
The bar chart below shows how Halvorsen 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 Halvorsen surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
