Origin
Meaning and origin of Dipietro
The surname DiPietro originated in Italy. It is a locational name derived from the Italian words "di" meaning "from" and "Pietro" meaning "Peter". The name refers to someone who either lived near a church dedicated to St. Peter or came from a place named after the saint.
DiPietro is most commonly found in southern Italy, particularly in the regions of Campania, Basilicata, and Calabria. It first appeared in historical records as early as the 12th century, with variations in spelling such as Di Pietro, De Pietro, and Dipietro.
One of the earliest recorded instances of the name is in the Codex Diplomaticus Regni Siciliae, a collection of medieval Sicilian charters from the 11th to the 14th century. The name appears several times, indicating its presence in Sicily during this period.
In the 14th century, a nobleman named Niccolò DiPietro was mentioned in chronicles for his role in the defense of the city of Salerno during the wars between the Kingdoms of Naples and Sicily.
During the Renaissance, a notable figure with the surname DiPietro was Pietro Antonio DiPietro, a renowned sculptor from Naples who lived from 1470 to 1538. He was responsible for creating several beautiful works of art that adorned churches and palaces across Italy.
Another prominent individual was Girolamo DiPietro, a philosopher and theologian from Calabria who lived from 1589 to 1651. He was a professor at the University of Naples and wrote extensively on topics such as metaphysics and natural philosophy.
In the 18th century, a famous composer named Giovanni Battista DiPietro hailed from Naples. Born in 1707, he composed numerous operas and sacred works that were widely performed throughout Italy during his lifetime.
The surname DiPietro has also been associated with several place names in Italy, such as San Pietro in Amantea, a town in Calabria, and San Pietro in Guarano, a village in Campania. These locations may have contributed to the name's origin and early distribution.

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 Dipietro 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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
