Origin
The surname Guerriero is of Italian origin, with its roots tracing back to the medieval period. It is derived from the Italian word "guerriero," which means "warrior" or "soldier." This suggests that the surname was initially bestowed upon individuals who were known for their military prowess or involvement in armed conflicts.
One of the earliest recorded instances of the name Guerriero can be found in the historic records of the city of Naples, dated back to the 14th century. During this time, the Kingdom of Naples was embroiled in various territorial disputes and wars, and it is likely that the name was attributed to a distinguished soldier or military leader from the region.
The surname Guerriero has also been linked to the town of Guerriero, located in the province of Avellino, Campania region of southern Italy. It is possible that the name originated from this specific location and was subsequently adopted by families residing in or near the town.
Historically, the Guerriero family played a significant role in the political and cultural landscape of Italy. One notable figure was Ettore Guerriero (1844-1920), an Italian politician and statesman who served as the Minister of Public Works in the late 19th century.
Another prominent individual with the Guerriero surname was Giuseppe Guerriero (1920-2008), an Italian sculptor and artist renowned for his works in bronze and marble. His sculptures can be found in various museums and public spaces throughout Italy.
Moving further back in time, records from the 16th century mention a nobleman named Gian Battista Guerriero, who was a prominent figure in the Kingdom of Naples during the Spanish rule. He is credited with overseeing the construction of several fortifications and defensive structures in the region.
In the world of literature, the surname Guerriero is associated with Vincenzo Guerriero (1909-1989), an Italian writer and poet who gained recognition for his works exploring themes of love, nature, and the human condition.
Another notable figure was Francesco Guerriero (1891-1963), an Italian military officer and aviator who served in World War I and played a crucial role in the development of the Italian Air Force during the interwar period.
While the surname Guerriero has its roots in Italy, it has since spread to various parts of the world, carried by Italian emigrants and their descendants. However, its origins and historical significance remain deeply rooted in the rich tapestry of Italian heritage and culture.
Demographics
Among Census respondents with the surname Guerriero, the largest self-reported group is White at 91.0%. The next largest groups are Hispanic (5.7%) and Two or More Races (2.0%).
The bar chart below shows how Guerriero 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 Guerriero 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.

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.
