Origin
The surname BERDUO is thought to have originated in the region of Friuli in northeastern Italy, near the borders of Slovenia and Austria. The name likely dates back to the medieval period, around the 12th or 13th century. It is believed to be derived from the Friulian word "berduel," which means "wild pear tree."
One of the earliest recorded instances of the name BERDUO appears in a 1296 document from the town of Udine, which refers to a landowner named Giacomo Berduo. This suggests that the family may have held some prominence or status in the area at that time.
In the 15th century, a branch of the Berduo family is known to have settled in the nearby town of Cividale del Friuli. Records from the local cathedral archive mention a Pietro Berduo, who served as a church warden in 1457.
Over the centuries, variations in the spelling of the name emerged, such as Berduò, Berdua, and Berduà. These variations likely reflect regional dialects and the evolving nature of written language.
One notable figure from history bearing the BERDUO name was Giovanni Battista Berduo (1572-1638), a Venetian architect and engineer. He was responsible for designing several important buildings in Venice, including the Church of San Moisè and the Palazzo Contarini dal Zaffo.
Another prominent individual was Marco Antonio Berduo (1612-1677), a Friulian scientist and mathematician. He made significant contributions to the field of optics and is credited with developing one of the earliest compound microscopes.
In the 18th century, a woman named Maria Berduo (1724-1805) gained recognition as a skilled lace maker in the city of Gorizia, which was then part of the Venetian Republic. Her intricate lace designs were highly sought after by wealthy patrons across Europe.
The BERDUO name also has connections to the wine industry in the Friuli region. In the late 19th century, a vintner named Giuseppe Berduo (1845-1912) established one of the first wineries in the area dedicated to producing the distinctive Friulian white wines.
Finally, a more recent figure of note was Guido Berduo (1898-1975), an Italian sculptor and artist known for his works in bronze and stone. Several of his public monuments and sculptures can be found in cities across northern Italy.
Demographics
Among Census respondents with the surname Berduo, the largest self-reported group is Hispanic at 96.9%. The next largest groups are White (2.3%) and American Indian/Alaska Native (0.5%).
The bar chart below shows how Berduo 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 Berduo 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.
