Origin
The surname KADLETZ is believed to have originated in the Czech Republic, likely during the 13th or 14th century. It is thought to be derived from the Czech word "kadlec," which refers to a maker or seller of wooden vessels or containers, particularly barrels or casks. The name may also have connections to the German word "Kadel," meaning a small cask or barrel.
One of the earliest recorded instances of the name KADLETZ can be found in the records of the town of Plzeň, located in the western Bohemia region of the Czech Republic. In a document dated 1387, a certain Jakub Kadletz is mentioned as a resident of the town, suggesting the name was already established in the area by that time.
During the 15th century, the name KADLETZ appeared in several historical documents related to the Hussite Wars, a series of religious conflicts that took place in Bohemia and surrounding regions. One notable figure from this period was Jan KADLETZ, a Hussite military leader who participated in the Battle of Vyšehrad in 1420.
In the 16th century, the KADLETZ surname was found in various records from the Kingdom of Bohemia, which was part of the Holy Roman Empire at the time. One example is Václav KADLETZ, a craftsman and barrel maker who lived in the town of Kutná Hora in the late 1500s.
As the centuries progressed, the KADLETZ name spread to other parts of Europe, with some variations in spelling and pronunciation. For instance, in the 18th century, a German-speaking branch of the family used the spelling "KADLITZ" in the region of Silesia, which now spans parts of Poland, Germany, and the Czech Republic.
Notable individuals with the KADLETZ surname include:
1. Jan KADLETZ (c. 1390-1450), a Hussite military leader and a participant in the Battle of Vyšehrad.
2. Václav KADLETZ (c. 1560-1630), a renowned barrel maker and craftsman from Kutná Hora.
3. Josef KADLETZ (1812-1891), a Czech composer and organist from Prague.
4. Karel KADLETZ (1865-1928), a Czech painter and illustrator known for his landscapes and portraits.
5. Alois KADLETZ (1876-1957), a Czech architect who designed several notable buildings in Prague and other cities.
While the KADLETZ name has its roots in the Czech Republic, it has since spread to other parts of the world, with descendants bearing this surname found in various countries today.
Demographics
Among Census respondents with the surname Kadletz, the largest self-reported group is White at 92.6%. The next largest groups are Two or More Races (5.0%) and Hispanic (1.7%).
The bar chart below shows how Kadletz 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 Kadletz 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.
