Origin
The surname Dotti originated in Italy, with its earliest known records dating back to the 14th century. It is believed to have derived from the Italian word "dotta," meaning "learned" or "erudite," suggesting a connection to scholars or educated individuals.
The name Dotti initially emerged in the regions of Tuscany and Umbria, where it was associated with notable families and intellectuals. One of the earliest documented references to the name can be found in the records of the city of Perugia, where a certain Giacomo Dotti was mentioned in a legal document from 1387.
During the Renaissance period, the Dotti surname gained prominence as several individuals bearing this name made significant contributions to the arts and sciences. One notable example is Andrea Dotti (1524-1586), a renowned Italian architect and sculptor who was commissioned to design several churches and palaces in Rome and other Italian cities.
Another prominent figure with the Dotti surname was Bartolomeo Dotti (1639-1713), a celebrated Italian painter and engraver from Florence. His works, which included religious paintings and portraits, can be found in various galleries and churches throughout Italy.
In the 18th century, the Dotti name was also associated with the Italian philosopher and writer, Giuseppe Dotti (1720-1789), who was known for his works on metaphysics and ethics. His writings influenced the intellectual discourse of his time and contributed to the development of modern philosophical thought.
Venturing outside of Italy, the Dotti surname can also be found in other European countries, although its origins can be traced back to the Italian peninsula. For instance, in France, there was a notable philosopher and mathematician named Jacques Dotti (1670-1737), who made significant contributions to the fields of geometry and calculus.
While the surname Dotti is not as common today as it once was, it remains a part of the rich tapestry of Italian heritage and cultural history, with its roots firmly planted in the realms of scholarship, arts, and intellectual pursuits.
Demographics
Among Census respondents with the surname Dotti, the largest self-reported group is White at 73.9%. The next largest groups are Hispanic (20.7%) and Two or More Races (2.7%).
The bar chart below shows how Dotti 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 Dotti 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.
