Origin
The surname CARLBLOM has its origins in Sweden, dating back to the 16th century. It is believed to be derived from the Swedish words "karl," meaning a man or fellow, and "blom," meaning flower or blossom. This combination suggests the name may have initially referred to someone with a floral name or occupation related to flowers.
CARLBLOM is thought to have originated in the southern regions of Sweden, particularly in the provinces of Skåne and Halland. Historical records from this period indicate variations in spelling, such as Karlblom, Carlblohm, and Carlbloem, reflecting regional dialects and the influence of other languages like Danish and German.
One of the earliest known references to the name CARLBLOM can be found in the parish records of Falkenberg, Halland, from the late 16th century. These records document the birth and baptism of a child named Nils Carlblom in 1587.
In the 17th century, the name appears in various Swedish military records, suggesting individuals with this surname may have served in the Swedish armed forces. One notable example is Olof Carlblom, a soldier who fought in the Thirty Years' War (1618-1648) under the command of King Gustavus Adolphus.
The 18th century saw the emergence of several prominent individuals bearing the CARLBLOM surname. Johan Carlblom (1707-1768) was a Swedish botanist and physician who made significant contributions to the study of plant taxonomy and medicinal plants. Another noteworthy figure was Anders Carlblom (1751-1827), a Swedish politician and member of the Riksdag, the national parliament.
In the 19th century, the name CARLBLOM was associated with several accomplished artists and intellectuals. Carl Olof Carlblom (1810-1876) was a renowned Swedish landscape painter, known for his depictions of Swedish rural scenery. Mathilda Carlblom (1853-1935) was a pioneering Swedish journalist and feminist, who advocated for women's rights and equal opportunities.
The 20th century witnessed the continued presence of CARLBLOM in various fields. Sven Carlblom (1901-1984) was a Swedish architect who designed several notable buildings in Stockholm, including the Stockholm Concert Hall. Gunnar Carlblom (1918-2004) was a Swedish diplomat and ambassador who served in various countries, including the United States and the Soviet Union.
Demographics

The bar chart below shows how Carlblom 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 Carlblom 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.
