Origin
The surname LATTANZE originated in Italy, with its earliest known records dating back to the 15th century. It is believed to have derived from the Italian word "lattanza," which means "milk" or "lactation." This suggests that the name may have been associated with those involved in the dairy industry or those living in areas known for their dairy production.
One of the earliest recorded instances of the LATTANZE surname can be found in the archives of the city of Siena, where a document from 1482 mentions a certain Giovanni LATTANZE, a farmer and cheese maker. Another notable mention is in a legal document from the city of Florence in 1517, which includes the name of a merchant named Tommaso LATTANZE.
During the 16th century, the LATTANZE family seems to have spread to other regions of Italy, with records indicating their presence in the cities of Naples and Palermo. One notable figure from this period was Antonio LATTANZE (1529-1592), a renowned sculptor and architect who worked on several prominent churches and palaces in Naples.
In the 17th century, the LATTANZE name appears in various historical records from the Papal States, with several members of the family holding positions within the Catholic Church. One such figure was Cardinal Pietro LATTANZE (1623-1697), who served as a diplomat and advisor to Pope Innocent XI.
As the centuries progressed, the LATTANZE surname continued to be found throughout Italy, with some families also migrating to other parts of Europe and the Americas. In the 19th century, a notable figure was the Italian writer and poet Giuseppina LATTANZE (1828-1892), whose works explored themes of love, nature, and the human experience.
Other notable individuals bearing the LATTANZE surname include:
1. Luciano LATTANZE (1901-1987), an Italian painter and sculptor known for his abstract works.
2. Maria LATTANZE (1912-1998), an Italian opera singer who performed at renowned venues such as La Scala in Milan.
3. Giancarlo LATTANZE (1935-2011), an Italian film director and screenwriter, best known for his collaborations with acclaimed directors like Fellini and Pasolini.
4. Stefano LATTANZE (born 1972), an Italian architect and urban planner who has worked on several high-profile projects in major cities across Europe.

Demographics
Among Census respondents with the surname Lattanze, the largest self-reported group is White at 84.0%. The next largest groups are Hispanic (5.0%) and Two or More Races (5.0%).
The bar chart below shows how Lattanze 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 Lattanze 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.
