Origin
The surname Risolo is believed to have originated in Italy, likely in the region of Lombardy or Veneto, during the Middle Ages. It is thought to be derived from the Italian word "risola," which means "small island" or "islet." This suggests that the name may have been initially given to someone who lived on or near a small island.
One of the earliest recorded instances of the name Risolo can be found in a 14th-century document from the city of Venice, where a certain Giovanni Risolo is mentioned as a merchant and landowner. Another early reference comes from a 15th-century manuscript from the town of Mantua, which mentions a family with the surname Risolo residing in the area.
In the 16th century, the name Risolo appears in records from the city of Verona, where a notable figure named Antonio Risolo (1492-1567) was a renowned painter and architect. His works can still be seen in various churches and palaces throughout the Veneto region.
During the 17th century, the Risolo family seems to have spread to other parts of Italy, as evidenced by the birth of Giulio Risolo (1616-1682) in the city of Naples. Giulio Risolo became a respected scholar and philosopher, known for his contributions to the study of natural sciences.
Another noteworthy individual with the surname Risolo was Isabella Risolo (1738-1812), who was born in the town of Parma. She gained recognition as a talented opera singer and performed in several prestigious theaters across Europe during the late 18th and early 19th centuries.
Over the centuries, variations in the spelling of the name have emerged, such as Risolli, Risol, and Risola, likely due to regional differences and phonetic adaptations. Additionally, some families may have adopted the name Risolo after migrating from small islands or coastal areas in Italy.
While the surname Risolo is not among the most common Italian surnames, it has a rich history and connections to various regions of Italy, particularly in the northern and central parts of the country. The name's association with small islands or islets is a unique characteristic that sets it apart and adds to its distinctiveness.
Demographics
Among Census respondents with the surname Risolo, the largest self-reported group is White at 96.2%. The next largest groups are Two or More Races (2.8%) and Black (0.9%).
The bar chart below shows how Risolo 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 Risolo 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.
