Origin
Meaning and origin of Suzio
The surname Suzio originated in Italy, with the earliest records dating back to the 14th century. It is believed to have derived from the medieval Italian word "sozzo," which means "dirty" or "unclean." This suggests that the name may have been initially given as a nickname to someone with an unkempt or disheveled appearance.
The Suzio family is thought to have originated from the region of Campania, particularly in the areas around Naples and Salerno. Historical records indicate that the name was prevalent in these areas during the medieval and Renaissance periods.
One of the earliest documented references to the Suzio surname can be found in a 14th-century manuscript from the city of Naples, where a certain "Giovanni Suzio" is mentioned as a merchant and landowner. This record provides evidence of the name's existence and use during that time period.
In the 15th century, the Suzio family gained prominence in the city of Salerno, where several members held positions of importance within the local government and clergy. Notably, a certain "Matteo Suzio" served as a magistrate in Salerno during the 1470s, while "Filippo Suzio" was a respected clergyman and scholar in the same city during the late 15th century.
Another notable figure bearing the Suzio surname was "Girolamo Suzio," a Renaissance-era painter and architect who lived in Naples during the 16th century. His works can still be found in various churches and buildings throughout the city.
In the 17th century, the Suzio family spread to other parts of Italy, with branches establishing themselves in cities like Rome and Milan. One of the most prominent individuals from this period was "Carlo Suzio," a renowned jurist and legal scholar who served as a judge in the papal court during the reign of Pope Innocent XI in the late 1600s.
As the centuries passed, the Suzio surname continued to appear in various records and historical documents across Italy, indicating the family's enduring presence and influence in various regions of the country.

The bar chart below shows how Suzio 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 Suzio 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.
