Origin
The surname Goclowski is of Polish origin and dates back to the late Middle Ages. It is believed to have originated from the village of Goclow (also spelled Goclów or Gocłów) in central Poland, located in the historic region of Małopolska. The name Goclow itself is derived from the old Polish word "gocław," which means "a person from Goclaw."
One of the earliest recorded instances of the Goclowski surname can be found in the Polish land records from the 15th century, where a certain Jan Goclowski was mentioned as a landowner in the village of Goclow. This suggests that the surname was already in use by that time and was likely associated with the local gentry or nobility.
In the 16th century, the Goclowski family was known to have ties to the nearby city of Krakow, which was a major cultural and intellectual center of Poland during the Renaissance era. Some historical records from that period mention a scholar and writer named Piotr Goclowski (1520-1583), who was a professor at the prestigious Jagiellonian University in Krakow.
During the 17th century, the Goclowski name gained prominence in the Polish military. One notable figure was Stanisław Goclowski (1612-1679), a distinguished cavalry officer who fought in the Polish-Swedish Wars and was known for his bravery and leadership on the battlefield.
In the 18th century, the Goclowski surname was associated with the Polish gentry and landowners in the region of Galicia (now part of modern-day Ukraine and Poland). A prominent figure from this era was Tadeusz Goclowski (1738-1812), a wealthy landowner and philanthropist who supported local schools and charities.
As the Polish population spread throughout Europe and beyond, the Goclowski surname traveled with them. In the 19th century, a notable figure was Józef Goclowski (1825-1891), a Polish immigrant to the United States who became a successful businessman and community leader in the city of Chicago.
Throughout its history, the Goclowski surname has been associated with various professions, including academics, military officers, landowners, and entrepreneurs. While the name has evolved slightly in spelling and pronunciation over time, its roots can be traced back to the village of Goclow in central Poland, where the Goclowski lineage first emerged.
Demographics
Among Census respondents with the surname Goclowski, the largest self-reported group is White at 82.2%. The next largest groups are Hispanic (11.2%) and Black (3.7%).
The bar chart below shows how Goclowski 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 Goclowski 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.
