Origin
Meaning and origin of Judycki
The surname Judycki originates from Poland, having its roots traceable to the 16th century. It is derived from the Polish name Judycki, a diminutive form of the name Judka, which in turn comes from the Hebrew name Judah. This name was commonly used among Polish Jews during that period.
The earliest recorded instance of the Judycki surname can be found in the historical records of the town of Krakow, where a merchant named Marek Judycki was mentioned in a document dated 1587. It is believed that the name was initially adopted by a Jewish family that converted to Christianity, as was common practice during that time.
In the 17th century, the Judycki surname appeared in various Polish church records, such as baptismal and marriage registers. One notable example is the entry for the baptism of Katarzyna Judycki, daughter of Andrzej Judycki and Anna Kowalska, in the parish of Stary Sącz in 1642.
During the 18th century, the Judycki surname spread across different regions of Poland, with several families bearing this name residing in the cities of Warsaw, Poznań, and Lublin. One prominent individual was Jan Judycki, a Polish noble and landowner who lived from 1715 to 1783.
In the 19th century, the Judycki name gained recognition in the field of literature and academia. Stanisław Judycki (1836-1912) was a renowned Polish writer and journalist, known for his contributions to the development of Polish literary realism. Another notable figure was Franciszek Judycki (1845-1929), a Polish historian and professor at the University of Lviv.
Throughout history, several other individuals with the Judycki surname have made their mark in various fields. These include Józef Judycki (1802-1878), a Polish painter and art educator; Maria Judycka (1860-1932), a Polish novelist and short story writer; and Tadeusz Judycki (1901-1989), a Polish military officer and diplomat who served as the Polish ambassador to Turkey in the 1950s.

The bar chart below shows how Judycki 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 Judycki surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
