Origin
Meaning and origin of Dubnicka
The surname DUBNICKA originates from the Slovak region of central Europe. Its roots can be traced back to the 16th century, deriving from the Slovak word "dubnica," which refers to an oak forest or grove. The name likely originated in reference to individuals who lived near or worked in such oak forests.
The earliest recorded instances of the DUBNICKA surname appear in historical records from the Kingdom of Hungary, which encompassed parts of modern-day Slovakia during the 16th and 17th centuries. Several variations in spelling, such as Dubnitzka and Dubniczka, can be found in these early documents.
One notable historical reference is the mention of a Ján DUBNICKA in the municipal records of the town of Banská Bystrica, located in central Slovakia, in the year 1612. This record suggests that individuals bearing this surname were present in the region during that time period.
In the late 17th century, the DUBNICKA surname can be found in the records of the Moravian region, which was then part of the Austrian Empire but is now located in the Czech Republic. This suggests that individuals with this surname may have migrated or been part of historical population movements between these neighboring regions.
Prominent individuals who have borne the DUBNICKA surname include Andrej DUBNICKA (1725-1788), a Slovak Catholic priest and author who wrote several religious texts in the Slovak language. Another notable figure was Jozef DUBNICKA (1842-1915), a Slovak lawyer and political activist who played a role in the Slovak national revival movement of the 19th century.
Other individuals with this surname include Anna DUBNICKA (1878-1958), a Slovak writer and teacher who contributed to the development of Slovak literature, and Michal DUBNICKA (1905-1982), a Slovak composer and conductor who was known for his orchestral works and film scores.
It is worth noting that the DUBNICKA surname may have undergone slight variations in spelling or pronunciation in different regions or time periods, but its origins can be firmly traced back to the oak forests of central Europe and the Slovak language.

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 Dubnicka surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
