Origin
The surname Sundlie originates from Norway, with its roots dating back to the 9th century. The name is derived from the Old Norse word "sundr," meaning "apart" or "asunder," and is believed to have been initially used as a descriptive surname for someone who lived in a remote or isolated location.
One of the earliest recorded instances of the Sundlie surname can be found in the Diplomatarium Norvegicum, a collection of Norwegian medieval documents from the 12th to the 16th centuries. This collection includes references to individuals with variations of the name, such as "Sundri" and "Sundre."
In the 14th century, the Sundlie name appeared in the Tingbok fra Hardanger, a medieval court record from the Hardanger region of Norway. This document mentions a man named Eirik Sundlie, who was involved in a legal dispute over land ownership.
During the 16th and 17th centuries, the Sundlie name gained prominence in the Numedal valley of southern Norway. Several notable individuals from this area bore the surname, including Halvor Sundlie (1560-1638), a respected farmer and landowner, and Ingrid Sundlie (1612-1687), a skilled weaver and textile artist.
In the 18th century, the Sundlie name spread to other parts of Norway, with records showing individuals bearing the surname in the regions of Telemark, Østfold, and Trøndelag. One prominent figure from this period was Nils Sundlie (1726-1801), a respected Lutheran minister who served in the parish of Vågå.
As Norwegians began immigrating to other parts of the world, particularly North America, in the 19th and early 20th centuries, the Sundlie surname traveled with them. Notable individuals from this era include:
1. Erik Sundlie (1858-1923), a Norwegian-American businessman and community leader in Seattle, Washington.
2. Anna Sundlie (1871-1952), a Norwegian-American author and educator who wrote extensively about Norwegian culture and folklore.
3. Ola Sundlie (1880-1963), a Norwegian-American farmer and politician who served in the North Dakota State Legislature.
4. Knut Sundlie (1892-1978), a Norwegian-American artist known for his landscape paintings of the Pacific Northwest.
5. Ingrid Sundlie (1905-1989), a Norwegian-American operatic soprano who performed with the New York City Opera and the San Francisco Opera.
While the Sundlie surname may have evolved and spread across various regions over the centuries, its origins can be traced back to the rugged landscapes of ancient Norway, where it reflected the isolated and remote dwellings of its earliest bearers.
Demographics
Among Census respondents with the surname Sundlie, the largest self-reported group is White at 82.1%. The next largest groups are Two or More Races (10.4%) and Hispanic (4.7%).
The bar chart below shows how Sundlie 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 Sundlie 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.
