Origin
Meaning and origin of Delsing
The surname Delsing has its origins in Sweden, dating back to the 16th century. It is derived from the Old Swedish word "del," which means "valley," and the suffix "-sing," indicating a place of origin or residence. This suggests that the name was originally associated with someone who lived in or near a particular valley.
One of the earliest recorded instances of the name Delsing can be found in the Swedish census records from the late 1500s, where it appears as "Delsinge." This variation in spelling was common during that time period, as standardized spelling conventions were not yet firmly established.
In the 17th century, the name Delsing appeared in various local records and documents from the province of Västergötland in southern Sweden. This region was known for its fertile valleys and agricultural communities, which aligns with the meaning of the name.
Notable individuals bearing the surname Delsing include Johan Delsing (1655-1720), a Swedish politician and member of the Riksdag (the national parliament) in the late 17th century. Another prominent figure was Carl Delsing (1782-1861), a Swedish military officer who served during the Napoleonic Wars.
In the 19th century, the Delsing family produced several notable academics and scholars, such as Gustaf Delsing (1834-1912), a professor of linguistics at Uppsala University, and his son, Nils Delsing (1868-1945), who followed in his father's footsteps and became a renowned linguist and philologist.
Another individual of note was Ingrid Delsing (1892-1978), a Swedish author and poet who gained recognition for her works exploring themes of nature and rural life. Her poetry collections, such as "Från bygdens stigar" (From the Village Paths), published in 1924, captured the essence of traditional Swedish village life.
While the surname Delsing is not among the most common in Sweden, it has a long and interesting history rooted in the country's rural landscapes and cultural traditions. The name's origin and meaning reflect the connection between people and the natural environment, particularly the valleys that shaped their lives and livelihoods.

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 Delsing 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.
