Origin
The surname Antonio is of Italian origin, originating from the ancient Roman name Antonius. It is believed to have derived from the Latin word "Antor," meaning "priceless" or "invaluable."
The name Antonio first appeared in historical records during the Roman Empire, with notable figures such as Marcus Antonius, the Roman politician and general who was a key figure in the Roman Republic's transformation into the Roman Empire. He lived from 83 BC to 30 BC.
In the Middle Ages, the name Antonio gained popularity in Italy, particularly in the regions of Tuscany, Lazio, and Campania. It appeared in various medieval documents and manuscripts, including the famous Florentine tax records known as the "Catasto" from the 14th century.
One of the earliest recorded examples of the surname Antonio dates back to the 12th century, when a nobleman named Guglielmo Antonio was mentioned in a legal document from the city of Siena in 1187.
The surname Antonio has also been associated with several notable historical figures. One prominent example is Antonio Vivaldi, the renowned Baroque composer and virtuoso violinist, who lived from 1678 to 1741. Another notable figure is Antonio Canova, the influential Neoclassical sculptor from the late 18th and early 19th centuries (1757-1822).
Other famous individuals with the surname Antonio include Antonio Machado, the influential Spanish poet and philosopher (1875-1939), and Antonio Guzmán Blanco, the Venezuelan military leader and politician who served as the country's president from 1870 to 1888 (1829-1899).
Additionally, the surname Antonio has been linked to various place names throughout Italy, such as the town of Sant'Antonio Abate in the province of Naples, and the village of Sant'Antonio di Gallura in Sardinia, further emphasizing its deep roots in the country's history and geography.
Demographics
Among Census respondents with the surname Antonio, the largest self-reported group is Hispanic at 52.1%. The next largest groups are Asian/Pacific Islander (23.4%) and White (12.8%).
The bar chart below shows how Antonio 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 Antonio 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.
