Origin
The surname Mastrovito originated in Italy and dates back to the medieval era. It is believed to have first appeared in the southern regions of the country, particularly in the areas around Naples and Salerno. The name is derived from the Italian words "mastro" meaning "master" and "vito" meaning "life," suggesting it may have referred to an esteemed person or someone who excelled in a particular trade or vocation.
One of the earliest recorded instances of the Mastrovito name can be found in the Codice Diplomatico Barese, a collection of historical documents from the city of Bari in southern Italy, dating back to the 11th century. The name is also mentioned in various administrative records and legal documents from the same period across the region.
In the 13th century, a nobleman named Guglielmo Mastrovito (born around 1220) was a prominent figure in the court of Frederick II, the Holy Roman Emperor and King of Sicily. He was known for his diplomatic skills and served as an ambassador for the Emperor in negotiations with the Papal States.
During the Renaissance, the Mastrovito family established itself in the city of Naples, where they were known as successful merchants and bankers. One notable member was Giovanni Battista Mastrovito (1470-1548), who was a wealthy financier and philanthropist. He funded the construction of several churches and charitable institutions in the city.
In the 17th century, a branch of the Mastrovito family migrated to the island of Sicily, where they settled in the town of Castelbuono. Here, they became involved in the production and export of wine and olive oil. A prominent figure from this era was Francesco Mastrovito (1625-1698), who was a respected vintner and landowner.
Another notable individual was Antonio Mastrovito (1780-1854), a lawyer and political activist from the town of Salerno. He played a role in the revolutionary movements of the early 19th century, advocating for democratic reforms and the unification of Italy.
While the Mastrovito name may have evolved over time with slight variations in spelling or pronunciation, it has maintained a strong presence in southern Italy, particularly in the regions of Campania, Basilicata, and Sicily, where many descendants of the original Mastrovito families still reside.
Demographics
Among Census respondents with the surname Mastrovito, the largest self-reported group is White at 86.6%. The next largest groups are Hispanic (10.9%) and Asian/Pacific Islander (2.5%).
The bar chart below shows how Mastrovito 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 Mastrovito 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.
