Origin
The surname Kozitza is believed to have originated in the region of present-day Poland and Ukraine during the medieval period, likely between the 12th and 15th centuries. It is thought to derive from the Slavic word "kozak," meaning a free man or Cossack warrior. The earliest recorded instances of this surname can be traced back to the areas surrounding the city of Krakow in southern Poland.
One of the earliest known references to the name Kozitza can be found in a manuscript dating back to the 14th century, which documents a land dispute between a nobleman named Jan Kozitza and a neighboring landowner. This provides evidence that the name was already in use among the nobility and landowning classes of the region at that time.
In the 16th century, a prominent military commander named Stanislaw Kozitza is recorded as having led a contingent of Polish cavalry during the Polish-Lithuanian Commonwealth's conflicts with the Ottoman Empire. He was born in 1542 and died in battle in 1603, leaving behind a legacy as a skilled tactician and fearless warrior.
The surname Kozitza also appears in several historical records related to the town of Kozitza, located in the Subcarpathian Voivodeship (present-day southeastern Poland). This suggests that the name may have originated from or been associated with this particular location, although the precise connection remains uncertain.
Another notable individual bearing the Kozitza surname was Andrzej Kozitza, a scholar and philosopher who lived in the late 17th century. Born in 1654 in the city of Lviv (then part of the Polish-Lithuanian Commonwealth, now in Ukraine), he is remembered for his contributions to the field of ethics and his writings on moral philosophy.
During the 19th century, a wealthy merchant named Tadeusz Kozitza made his mark in the city of Warsaw. He was born in 1789 and established a successful trading business, becoming one of the most influential businessmen in the region. His legacy can still be seen in the form of the Kozitza Family Foundation, which he established to support educational and charitable causes.
Demographics
Among Census respondents with the surname Kozitza, the largest self-reported group is White at 100.0%.
The bar chart below shows how Kozitza 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 Kozitza 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.
