Origin
The surname Montaperto is of Italian origin, originating in the region of Calabria in southern Italy. It likely emerged during the Middle Ages, sometime between the 11th and 15th centuries.
Montaperto is derived from the Italian words "monte" meaning mountain, and "aperto" meaning open or exposed. This suggests the name may have referred to a person living in an open or exposed area near a mountain. Alternatively, it could have described a location with a prominent mountain or hill.
The earliest known record of the Montaperto name dates back to the 13th century. An individual named Giovanni Montaperto was mentioned in a legal document from the town of Cosenza in 1273. This suggests the name was already well-established in the region by that time.
In the 14th century, a Andrea Montaperto was a renowned scholar and philosopher who taught at the University of Naples. He was born in 1320 and died in 1385. His writings on logic and metaphysics were widely studied and influential during the Renaissance period.
Another notable figure was Pietro Montaperto, a 16th-century painter from the city of Reggio Calabria. He was known for his religious works and frescoes adorning churches in southern Italy. Pietro Montaperto was born in 1525 and died in 1595.
In the 18th century, a Francesco Montaperto was a prominent landowner and farmer in the Calabrian town of Corigliano Calabro. Records from 1753 show he owned a vast estate and was one of the wealthiest individuals in the region at the time.
The name Montaperto has also been associated with various place names in Calabria, such as the village of Montaperto near Cosenza, and the Montaperto mountain range in the province of Reggio Calabria. These geographical features likely predate the use of the surname and may have influenced its origin.
While not as common today, the Montaperto surname continues to be found primarily in southern Italy, particularly in Calabria and Sicily. It serves as a reminder of the rich history and geographic influences that have shaped Italian surnames over centuries.
Demographics
Among Census respondents with the surname Montaperto, the largest self-reported group is White at 86.0%. The next largest groups are Hispanic (13.2%) and Asian/Pacific Islander (0.8%).
The bar chart below shows how Montaperto 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 Montaperto 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.
