Origin
The surname "TWEIT" is of Norwegian origin, with its roots traced back to the early Middle Ages. This name is derived from the Old Norse word "tveita," which means "a clearing" or "a patch of land." It is believed that the name originally referred to people who lived or worked on such a clearing or patch of land.
One of the earliest recorded instances of the name "TWEIT" can be found in the Diplomatarium Norvegicum, a collection of medieval Norwegian documents from the 12th to the 16th centuries. In this collection, the name appears as "Tveiten," which was a common spelling variation during that time period.
The name "TWEIT" has also been documented in various Norwegian farm names and place names throughout history. For example, the village of Tveit in Vestfold County, Norway, is believed to have derived its name from the same root word as the surname.
Among the notable historical figures bearing the surname "TWEIT" is Ola Tveiten (1832-1913), a Norwegian farmer and politician who served as a member of the Storting, the Norwegian parliament, in the late 19th century.
Another prominent individual with this surname was Olav Tveiten (1890-1973), a Norwegian theologian and professor at the University of Oslo. He made significant contributions to the field of religious studies and authored several scholarly works on Christianity.
In the 18th century, there was a Norwegian farmer and landowner named Bjørn Tveiten (1712-1786), who was known for his agricultural innovations and expertise in cultivating various crops.
The name "TWEIT" also appears in the records of Norwegian immigrants to the United States in the 19th and early 20th centuries. One such individual was Knut Tveiten (1865-1947), who settled in Minnesota and became a prominent figure in the local Norwegian-American community.
Another notable person with this surname was Ingrid Tveiten (1905-1988), a Norwegian-American artist and painter who was renowned for her landscapes and depictions of rural life in Norway and the American Midwest.
Demographics
Among Census respondents with the surname Tweit, the largest self-reported group is White at 100.0%.
The bar chart below shows how Tweit 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 Tweit 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.
