Origin
Meaning and origin of Giuliana
The surname Giuliana has its origins in Italy. It is derived from the medieval Italian given name Giuliana, which itself is a feminine form of the name Giuliano. The name Giuliano can be traced back to the Roman family name Julianus, which was derived from the gens (clan) name Julius.
The name Julius was a prominent Roman name, borne by several notable historical figures, including the Roman dictator Julius Caesar. It is believed that the gens name Julius may have originated from the Greek word ioulos, meaning "downy-bearded" or "curly-haired."
The earliest recorded instances of the surname Giuliana can be found in medieval Italian records from the 12th and 13th centuries. One of the earliest known bearers of the surname was Giuliana di Montefeltro, who lived in the late 12th century and was a member of the noble Montefeltro family of Urbino, a city in the Marche region of central Italy.
Another notable early bearer of the surname was Giuliana Gonzaga (c. 1466-1542), an Italian noblewoman and patron of the arts. She was a member of the powerful Gonzaga family, which ruled the Duchy of Mantua in northern Italy during the Renaissance period.
During the 15th and 16th centuries, the surname Giuliana was particularly concentrated in the regions of Tuscany, Umbria, and Lazio in central Italy, as well as in the Veneto region of northeastern Italy. It was also found in various forms, such as Giuliani, Giulianini, and Giulianetti.
In the 17th century, a notable bearer of the surname was Giuliana Morosina (1608-1678), a Venetian noblewoman and writer who authored several works on the history and culture of Venice.
Another prominent figure with the surname Giuliana was Giuliana Evangelisti (1744-1818), an Italian painter and engraver from Bologna who specialized in portraiture and religious subjects.
As the surname Giuliana spread throughout Italy and beyond, it underwent various spelling variations, such as Giuliani, Giulianini, and Giulianetti, reflecting regional linguistic differences and preferences.

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 Giuliana surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
