Origin
The surname Kociemba is of Polish origin, originating in the 16th century. It is derived from the Polish word "kocioł," meaning "cauldron" or "kettle," and the diminutive suffix "-emba." This suggests that the name may have originally referred to someone who made or worked with cauldrons or kettles.
The earliest recorded instances of the name Kociemba can be found in historical records from the Kraków region of Poland. In the 16th century, the name appears in various municipal and church records, indicating that it was already established in this area.
One of the earliest known individuals with the surname Kociemba was Jan Kociemba, a blacksmith who lived in the village of Mogilany near Kraków in the late 16th century. His name is recorded in the parish records of the local church.
In the 17th century, the name Kociemba can be found in the records of the city of Kraków itself. Bartłomiej Kociemba, a merchant and tradesman, is mentioned in the city's guild records from the 1640s.
As the name spread beyond its original region, variations in spelling emerged. In the 18th century, records from the Lublin region of eastern Poland show instances of the name spelled as "Kociamba" or "Koczemba."
One notable figure with the surname Kociemba was Franciszek Kociemba, a Polish military officer who served in the Napoleonic Wars in the early 19th century. He was born in 1785 and fought in several major battles, including the Battle of Leipzig in 1813.
Another individual of historical significance was Józef Kociemba, a Polish Catholic priest and writer who lived in the late 19th century. He was born in 1848 and authored several religious works and theological treatises.
In the 20th century, the name Kociemba gained wider recognition with Zbigniew Kociemba, a Polish mathematician and computer scientist who made significant contributions to the field of combinatorial game theory. He was born in 1935 and published numerous papers and books on game theory and related topics.
The surname Kociemba has also been associated with several place names in Poland, such as the village of Kociembów in the Lublin region, which may have derived its name from the surname itself or vice versa.
While the exact origins of the name Kociemba remain somewhat obscure, its historical records and variations provide insights into its evolution and spread throughout Poland over the centuries. The name continues to be carried by individuals of Polish descent around the world today.
Demographics
Among Census respondents with the surname Kociemba, the largest self-reported group is White at 90.3%. The next largest groups are Two or More Races (5.9%) and Hispanic (3.2%).
The bar chart below shows how Kociemba 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 Kociemba 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 Kociemba (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.
