Origin
The surname "CZYZ" has its origins in Poland. It is a Polish occupational surname derived from the Polish word "czyz", which means a finch or a type of small songbird. The name likely originated in the Middle Ages and referred to someone who caught or kept finches, possibly a hunter or a birdcatcher by trade.
The earliest recorded instances of the surname "CZYZ" can be traced back to the 15th century in various regions of Poland. It was commonly found in areas such as Lesser Poland, Masovia, and the Kraków region. The name appears in historical records and documents from that time period, including parish registers and court records.
One notable historical reference to the surname "CZYZ" is found in the "Akta Grodzkie i Ziemskie" (District and Land Records) from the 16th century, which were official documents of legal proceedings in the Polish-Lithuanian Commonwealth. These records mention individuals with the surname "CZYZ" involved in various legal matters and transactions.
Among the earliest recorded individuals with the surname "CZYZ" was Jan Czyz, who lived in the town of Przytyk in the Masovian Voivodeship in the late 15th century. Another early bearer of the name was Jakub Czyz, a resident of the village of Wierzawice in the Kraków region, mentioned in parish records from the early 16th century.
Throughout history, there have been several notable individuals with the surname "CZYZ". One such person was Katarzyna Czyz (1626-1688), a Polish noblewoman and landowner from the szlachta (noble) class, who owned estates in the Lublin region. Another was Piotr Czyz (1790-1853), a Polish painter and artist known for his landscapes and religious works.
Other individuals with the surname "CZYZ" include Walenty Czyz (1807-1867), a Polish writer and poet from the Romantic period, and Józef Czyz (1859-1922), a Polish military officer and general who served in the Polish Legions during World War I. In more recent times, Andrzej Czyz (1938-2008) was a prominent Polish actor and director in theater and film.
The surname "CZYZ" has remained relatively common in Poland over the centuries, with various spelling variations such as "Czyż" and "Czysz" also being used. While it has spread to other parts of the world through migration, its roots can be traced back to the Polish lands and the occupational origins related to the finch or small songbird.
Demographics
Among Census respondents with the surname Czyz, the largest self-reported group is White at 94.1%. The next largest groups are Hispanic (3.4%) and Two or More Races (1.6%).
The bar chart below shows how Czyz 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 Czyz 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.
