Origin
The surname Lucchetti originated in Italy, specifically in the region of Tuscany. It can be traced back to the medieval period, around the 12th or 13th century. The name is derived from the Italian word "lucchetto," which means "small lock" or "padlock." This suggests that the earliest bearers of this surname may have been locksmiths or metalworkers.
One of the earliest recorded mentions of the Lucchetti surname can be found in the archives of the city of Lucca, which dates back to the 14th century. The name also appears in various historical documents from other Tuscan cities, such as Florence and Siena, during the Renaissance period.
In the 15th century, a notable figure with the surname Lucchetti was Giovanni Lucchetti, a renowned goldsmith and jeweler from Florence. His intricate works were highly sought after by the wealthy families of the time.
Another prominent individual bearing this surname was Bartolomeo Lucchetti, a successful merchant and banker who lived in Siena during the 16th century. He was involved in financing several major construction projects in the city.
During the 17th century, the Lucchetti family expanded beyond Tuscany, with some members settling in other Italian regions, such as Emilia-Romagna and Umbria. One notable figure from this period was Antonio Lucchetti, a celebrated painter from Bologna, who was known for his religious works and frescoes.
In the 18th century, a branch of the Lucchetti family established themselves in the region of Lazio, near Rome. One of their descendants, Giuseppe Lucchetti, was a respected architect who contributed to the design of several churches and palaces in the area.
As the Lucchetti surname spread throughout Italy, it also found its way into other European countries, particularly in regions with strong Italian influence or immigration. However, the name remains most prevalent in its place of origin, Tuscany, where it has been a part of the local heritage for centuries.
Demographics
Among Census respondents with the surname Lucchetti, the largest self-reported group is White at 89.2%. The next largest groups are Hispanic (6.2%) and Two or More Races (3.6%).
The bar chart below shows how Lucchetti 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 Lucchetti surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lucchetti (2000, 2010, 2020).
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.
