Origin
Meaning and origin of Tizio
The surname TIZIO is of Italian origin, with records dating back to the early 13th century. It is believed to have originated in the region of Tuscany, particularly in the city of Florence. The name is derived from the Italian word "tizio," which means "so-and-so" or "a certain person." This term was often used in legal documents to refer to an unnamed individual.
One of the earliest recorded instances of the surname TIZIO can be found in a Florentine document from the year 1245, which mentions a certain "Tizio di Berto." This suggests that the name may have initially been used as a nickname or a way to identify someone whose given name was unknown.
In the 14th century, the TIZIO surname gained prominence in Florence, with several notable individuals bearing the name. One such figure was Tizio da Castiglione, a renowned painter and illuminator who lived from around 1320 to 1380. His works can still be found in various churches and museums throughout Italy.
Another well-known TIZIO was Francesco Tizio, a humanist scholar and writer who lived from 1457 to 1517. He was the author of several historical works, including a chronicle of the city of Siena, which provides valuable insights into the political and cultural life of the time.
During the Renaissance period, the TIZIO surname was also associated with the powerful Medici family of Florence. One member, Tizio de' Medici (1480-1537), was a nobleman and military commander who served under the Medici rulers.
In the 16th century, the name TIZIO spread beyond Tuscany and can be found in other regions of Italy. One notable figure was Tizio Manlio (1550-1619), a jurist and legal scholar from Naples who authored several influential works on civil law.
As the centuries passed, the TIZIO surname continued to be prominent in various fields, including the arts, literature, and academia. Tizio Strozzi (1619-1668) was a renowned poet and dramatist from Venice, while Tizio Ariosto (1720-1789) was a respected philosopher and professor at the University of Padua.
While the TIZIO surname may have originated as a way to identify an unknown individual, it has since become a respected and well-established name in Italian history and culture, with a rich legacy spanning several centuries.

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 Tizio 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.
