The name is likely of occupational origin, indicating a person who worked as a moor or Muslim servant.
The earliest recorded instances of the name can be found in medieval Italian records and manuscripts from regions like Tuscany, Lombardy, and Emilia-Romagna. The name appeared in various spellings, such as Moreto, Moretta, and Moretto, reflecting regional variations in pronunciation and spelling conventions.
One notable historical reference to the name Moretti can be found in the "Codice Diplomatico Longobardo," a collection of Lombard diplomatic documents from the 8th to the 12th centuries. This source mentions individuals with the surname Moretti or variations thereof, suggesting the name's prevalence in northern Italy during the Middle Ages.
Among the notable individuals who bore the surname Moretti throughout history are:

Demographics
Among Census respondents with the surname Moretti, the largest self-reported group is White at 89.1%. The next largest groups are Hispanic (7.5%) and Two or More Races (2.3%).
The bar chart below shows how Moretti 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 Moretti 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.
