Origin
The surname IABONI has its origins in Italy, with records dating back to the 16th century. It is believed to have originated from the Italian word "iaboni," which means "farmers" or "cultivators." This suggests that the name was likely associated with those who worked in agriculture or tended to the land.
One of the earliest known references to the IABONI surname can be found in the historic records of the town of Abruzzo, located in central Italy. These records mention a family by the name of IABONI residing in the region during the mid-16th century. The name is also believed to have been present in other parts of Italy, such as Campania and Basilicata, during this time period.
In the 17th century, a notable figure bearing the IABONI surname was Giovanni IABONI, a renowned artist and sculptor from Naples. His works can still be found in various churches and museums throughout Italy, with some of his most famous pieces being the intricate marble carvings adorning the altars of the Duomo di Milano.
During the 18th century, the IABONI name gained further prominence with the birth of Francesco IABONI (1720-1792), a celebrated philosopher and writer from the town of Potenza in Basilicata. His literary works, which explored themes of ethics and morality, were widely acclaimed and contributed to the intellectual discourse of the time.
In the 19th century, the IABONI name made its way to the United States, with records indicating that several families bearing this surname arrived in the late 1800s, seeking new opportunities and a better life. One notable figure from this era was Antonio IABONI (1845-1912), a skilled stonemason who played a significant role in the construction of several iconic buildings in New York City, including the famous St. Patrick's Cathedral.
Another prominent individual with the IABONI surname was Maria IABONI (1875-1958), a dedicated educator and advocate for women's rights. Born in a small village in Abruzzo, she moved to Rome in the early 1900s and established one of the first schools for girls in the city, promoting the importance of education for women during a time when such opportunities were limited.
While the IABONI surname may not be as widespread as some others, it has left an indelible mark on history, with individuals bearing this name contributing to various fields, from art and literature to architecture and education. The name serves as a testament to the rich cultural heritage and resilience of those who carried it through the centuries.
Demographics
Among Census respondents with the surname Iaboni, the largest self-reported group is White at 90.5%. The next largest groups are Hispanic (5.6%) and Black (1.7%).
The bar chart below shows how Iaboni 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 Iaboni 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.
