Origin
The surname Korac is of Croatian origin, with its roots dating back to the 16th century. This surname was primarily found in the regions of Dalmatia and the Adriatic coast, where it likely originated from a Croatian word or phrase related to a person's occupation or physical attributes.
One theory suggests that Korac is derived from the Croatian word "korac," meaning "step" or "stride," possibly referring to someone who was known for their long strides or walking abilities. Another possibility is that it originated from the word "kora," meaning "bark" or "crust," which could have been a descriptive name for a person involved in forestry or related occupations.
In the earliest records, the name appeared with various spellings, such as Koracic, Koracevic, and Koracic, reflecting the regional dialects and variations in pronunciation. The first documented instances of the name can be traced back to the 16th century in the coastal towns of Split and Dubrovnik, where it was associated with prominent families and merchants.
One of the earliest known bearers of the Korac surname was Petar Korac, a merchant from Split who lived in the late 16th century. His name appeared in several trade records and contracts from that period, indicating the family's involvement in maritime commerce.
Another notable figure was Ivan Korac, a Croatian military officer who served in the Venetian army during the 17th century. He played a significant role in the defense of Dalmatia against Ottoman invasions and was mentioned in several chronicles and military dispatches from that time.
In the 18th century, the Korac family gained prominence in the town of Makarska, where they were landowners and involved in local governance. One member, Jure Korac (1740-1815), served as the town's mayor and was instrumental in the construction of several public buildings and infrastructure projects.
During the 19th century, the surname spread throughout Croatia and neighboring regions, with individuals bearing the name making contributions in various fields. Nikola Korac (1825-1892) was a renowned poet and writer from Dalmatia, whose works celebrated the region's cultural heritage and folklore.
In more recent times, the name Korac has been carried by several notable individuals, such as Žarko Korac (1909-1988), a Croatian economist and academic who made significant contributions to the field of economic theory and policy.
While the surname Korac has Croatian roots, it has also been found in other parts of the Balkans and Eastern Europe, likely due to migration patterns and intermarriage between different ethnic groups over the centuries.
Demographics
Among Census respondents with the surname Korac, the largest self-reported group is White at 80.2%. The next largest groups are Hispanic (10.3%) and Two or More Races (5.2%).
The bar chart below shows how Korac 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 Korac 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.
