Origin
The surname "KOZIK" is of Polish origin, originating in the 16th or 17th century. The name is believed to be derived from the Polish word "kosa," meaning "scythe," possibly indicating that the earliest bearers of the name were farmers or agricultural workers.
The earliest known record of the name "KOZIK" can be found in the parish records of the village of Wysokie Mazowieckie, located in the Podlaskie Voivodeship of northeastern Poland. These records date back to the late 16th century and include several entries for individuals with the surname "KOZIK."
In the late 17th century, the name appears in the records of the nearby town of Tykocin, where a family by the name of KOZIK owned a small farm and operated a blacksmith shop. This suggests that the name may have been associated with metalworking or agricultural implements in addition to farming.
One notable bearer of the surname "KOZIK" was Jan KOZIK (1589-1654), a Polish soldier who fought in the Polish-Swedish War of 1626-1629. He is mentioned in several historical accounts of the conflict and is believed to have been from the region around Wysokie Mazowieckie.
Another individual of note was Katarzyna KOZIK (1721-1798), a nun and educator who founded a school for girls in the town of Puławy in central Poland. The school, which operated for several decades in the 18th century, was one of the first of its kind in the region and played a significant role in promoting education for women.
In the 19th century, the surname "KOZIK" can be found in various records from the Galicia region, which at the time was part of the Austro-Hungarian Empire. This includes the birth records of Franciszek KOZIK (1832-1911), a farmer and landowner from the village of Jabłonka, near the modern-day border with Slovakia.
By the late 19th and early 20th centuries, the name had spread to other parts of Poland, as well as to neighboring countries with significant Polish populations, such as Ukraine and Belarus. One notable figure from this period was Stanisław KOZIK (1876-1958), a Polish-Ukrainian writer and journalist who was active in the early 20th century and published several works on the history and culture of the region.
Demographics
Among Census respondents with the surname Kozik, the largest self-reported group is White at 93.4%. The next largest groups are Hispanic (2.6%) and Two or More Races (2.0%).
The bar chart below shows how Kozik 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 Kozik 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.
