Origin
The surname ADELI originated in Italy during the medieval period. It is derived from the Italian word "adele," which means "noble" or "noble-born." This suggests that the name was initially given to individuals of noble or aristocratic descent.
The earliest recorded instances of the name can be found in historical documents from regions such as Tuscany and Emilia-Romagna, where it was commonly used by noble families and landowners. Some variations of the spelling include Adeli, Adelli, and Adele.
One of the earliest known bearers of the name was Adele di Canossa (1015-1088), a powerful Italian noblewoman and regent of the Holy Roman Empire. She played a significant role in the Investiture Controversy between the Papacy and the Holy Roman Empire.
Another notable figure was Gian Girolamo Adeli (1540-1615), an Italian architect and sculptor from Bologna. He designed several notable buildings in his hometown, including the Church of San Giacomo Maggiore and the Palazzo dei Banchi.
In the 16th century, the name appeared in the writings of the renowned Italian poet Torquato Tasso, who mentioned an Adeli family in his epic poem "Gerusalemme Liberata."
During the Renaissance period, the Adeli family was prominent in the city of Florence. One member, Benedetto Adeli (1459-1525), was a respected humanist scholar and diplomat who served as an ambassador for the Medici family.
In the 18th century, Giovanni Battista Adeli (1703-1775) was a celebrated Italian painter from Bologna. He was known for his religious and mythological works, which can be found in various churches and galleries across Italy.
While the name has its roots in Italy, it has since spread to other parts of the world through migration and cultural exchange. However, its earliest and most significant historical connections can be traced back to the noble families and prominent figures of medieval and Renaissance Italy.
Demographics
Among Census respondents with the surname Adeli, the largest self-reported group is White at 78.4%. The next largest groups are Asian/Pacific Islander (9.5%) and Two or More Races (8.1%).
The bar chart below shows how Adeli 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 Adeli 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.
