Origin
The surname Molfetto has its origins in Italy, specifically in the region of Puglia, where it can be traced back to the Middle Ages. The name is derived from the Italian town of Molfetta, located on the Adriatic coast, suggesting that the earliest bearers of this surname hailed from this picturesque seaside town.
Molfetta itself is a name of ancient Greek origin, with the root "molp" meaning "song" or "melody." This alludes to the town's proximity to the sea and its ties to maritime culture, where the rhythmic sounds of waves and the songs of sailors may have influenced the naming.
Historical records from the 12th and 13th centuries mention individuals with the surname Molfetto or variations like Molfetta or Molfetti, indicating their presence in the area during this period. One notable figure is Giovanni Molfetto, a merchant and landowner who lived in the late 13th century and was documented in the archives of the city of Bari.
In the 15th century, the name appears in Venetian records, suggesting that members of the Molfetto family had migrated to the famous maritime republic. One such individual was Antonio Molfetto, a ship captain who was involved in trade between Venice and the Levant in the mid-1400s.
The name also found its way to other parts of Italy, as evidenced by the presence of notable individuals like Girolamo Molfetto, a lawyer and scholar from Bologna who lived in the early 16th century and published several legal treatises.
In the 17th century, the name Molfetto gained prominence in the southern Italian city of Naples, where a family of that name produced several notable figures. One was Gian Battista Molfetto (1601-1678), a renowned architect who designed several churches and palaces in the city and its surrounding areas.
Another notable bearer of the Molfetto surname was Antonio Molfetto (1720-1788), a Neapolitan painter who specialized in landscapes and seascapes, reflecting the maritime heritage associated with the name's origins.
While the surname Molfetto is relatively uncommon outside of Italy, it has been carried by individuals of Italian descent to various parts of the world, particularly in the wake of the great Italian emigrations of the late 19th and early 20th centuries.
Demographics

The bar chart below shows how Molfetto 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 Molfetto 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.
