Origin
The surname Kostelic is of Croatian origin, with its roots tracing back to the early medieval period in the Balkans. It is believed to have derived from the Slavic word "kost," which means "bone," and was likely initially a descriptive nickname given to someone with a prominent or distinctive bone structure.
The earliest known records of the Kostelic surname date back to the 13th century, where it appeared in various forms such as Kostelich, Kostelić, and Kostelyč in ancient Croatian manuscripts and legal documents. These early spellings reflect the regional variations and linguistic shifts that occurred over time.
One of the earliest documented instances of the Kostelic name can be found in the Poljica Statute, a legal code from the Republic of Poljica, a semi-autonomous region in present-day Croatia. In this document, dated to the late 14th century, a certain Radovan Kostelić is mentioned as a witness to a land dispute.
During the Renaissance and Baroque periods, the Kostelic surname gained prominence among the Croatian nobility and intellectual circles. Notably, Ivan Kostelic (1567-1641) was a renowned Renaissance humanist, philosopher, and theologian who served as the Bishop of Zagreb and played a crucial role in promoting education and cultural development in Croatia.
Another notable bearer of the Kostelic name was Andrija Kostelic (1785-1858), a Croatian linguist and lexicographer who made significant contributions to the standardization of the Croatian language. His work, the "Lexicon of the Croatian Language," published in 1835, is considered a landmark in the development of modern Croatian lexicography.
In more recent history, the Kostelic surname gained international recognition through the achievements of Janica Kostelic (born 1982), a former Croatian alpine ski racer who won four Olympic gold medals and numerous World Cup titles. Her brother, Ivica Kostelic (born 1979), is also a highly successful alpine ski racer, with four Olympic silver medals and numerous World Cup victories to his name.
Other notable individuals with the Kostelic surname include Ante Kostelic (1899-1976), a Croatian sculptor known for his monumental works, and Stjepan Kostelic (born 1957), a former Croatian alpine ski racer and the father of Janica and Ivica Kostelic, who played a pivotal role in their athletic development.
While the Kostelic surname has its roots in Croatia, it has since spread to other parts of the world due to migration and intermarriage. However, its historical significance and association with notable figures in Croatian history and culture remain deeply ingrained in its legacy.
Demographics
Among Census respondents with the surname Kostelic, the largest self-reported group is White at 94.3%. The next largest groups are Asian/Pacific Islander (3.8%) and Hispanic (1.9%).
The bar chart below shows how Kostelic 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 Kostelic surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Kostelic (2000, 2010, 2020).
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.
