Origin
The surname Mattei is of Italian origin, specifically from the region of Tuscany. It is believed to have emerged during the late Middle Ages, around the 13th or 14th century. The name is derived from the Italian personal name Matteo, which itself comes from the Hebrew name Matityahu, meaning "gift of God."
One of the earliest recorded instances of the Mattei surname can be found in the Florentine Codex, a 16th-century manuscript that documents the history and customs of the Aztec people. This suggests that individuals bearing this name may have been among the early Italian explorers and settlers in the Americas.
The Mattei family was prominent in Florence during the Renaissance period. One notable figure was Alessandro Mattei (1504-1600), a wealthy banker and patron of the arts who commissioned works from renowned artists such as Raphael and Michelangelo.
Another prominent individual with the Mattei surname was Girolamo Mattei (1547-1603), a Roman Catholic prelate who served as the Bishop of Camerino and later as the Cardinal-Bishop of Palestrina. He played a significant role in the Catholic Reformation and was known for his strict adherence to Church doctrine.
In the 18th century, Antonio Mattei (1744-1832) was an Italian physicist and mathematician who made important contributions to the study of electricity and magnetism. He was a member of the prestigious Accademia dei Lincei, one of the oldest scientific academies in the world.
The Mattei surname can also be found in other parts of Italy, such as the island of Sicily. One notable figure from this region was Giuseppe Mattei (1808-1865), a Sicilian revolutionary and patriot who fought for the unification of Italy during the Risorgimento movement.
Throughout history, the Mattei surname has been associated with various professions, including banking, the clergy, academia, and politics. While the name has maintained its Italian roots, it has also spread to other parts of the world through migration and intermarriage.
Demographics
Among Census respondents with the surname Mattei, the largest self-reported group is White at 69.2%. The next largest groups are Hispanic (26.8%) and Two or More Races (2.2%).
The bar chart below shows how Mattei 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 Mattei 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 Mattei (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.
