Origin
The surname DANUBIO is of Italian origin and dates back to the 13th century. It is derived from the Latin word "Danubius," which was the name given to the Danube River, one of Europe's longest and most significant waterways. This suggests that the name may have originated from a place near the Danube River or from someone who lived or worked along its banks.
One of the earliest recorded instances of the surname DANUBIO can be found in a 1276 document from the city of Verona, which mentions a merchant named Giacomo DANUBIO. This indicates that the name was already established in the northern Italian region of Veneto during the late medieval period.
Throughout the 14th and 15th centuries, the DANUBIO surname appeared in various records across northern and central Italy, particularly in the regions of Lombardy, Emilia-Romagna, and Tuscany. This suggests that the name may have spread from its original location along the Danube River to other areas of the Italian peninsula.
In the 16th century, a prominent figure with the surname DANUBIO was the Italian Renaissance artist and architect Gian Battista DANUBIO (c. 1500-1575), who was born in Ferrara and worked on several notable buildings in his hometown and other parts of northern Italy.
Another notable bearer of the DANUBIO name was the 17th-century Italian mathematician and astronomer Giovanni Battista DANUBIO (1615-1692), who made significant contributions to the study of celestial mechanics and was a member of the Accademia dei Lincei, one of the oldest scientific academies in Europe.
In the 18th century, the name DANUBIO was found in various regions of Italy, including the southern part of the country. One example is the Neapolitan composer and music theorist Gennaro DANUBIO (1730-1805), who was a prominent figure in the Neapolitan school of music during the late Baroque and early Classical periods.
As the centuries passed, the DANUBIO surname continued to be present across Italy, with individuals bearing this name making contributions in various fields, such as literature, art, and academia. While the name may have evolved from its original connection to the Danube River, it has become a part of the rich tapestry of Italian surnames, carrying with it a long and storied history.
Demographics
Among Census respondents with the surname Danubio, the largest self-reported group is White at 94.2%. The next largest groups are Hispanic (1.9%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Danubio 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 Danubio 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.
