Origin
Meaning and origin of Alberti
The surname Alberti originated in Italy, with its earliest known roots dating back to the 12th century. It is believed to be derived from the medieval Italian personal name Alberto, which itself stems from the Germanic Adalbrecht, meaning "bright nobility." The Alberti family was one of the most prominent and influential noble families in Florence during the Renaissance period.
The name Alberti can be found in various historical records, including the Florentine Priorista, a chronicle of the city's rulers from the 13th to the 15th centuries. One of the earliest known individuals with this surname was Benedetto Alberti, a Florentine merchant and diplomat who lived from 1322 to 1388. Another notable figure was Leon Battista Alberti (1404-1472), a renowned Renaissance humanist, author, artist, architect, poet, and philosopher.
In the 15th century, the Alberti family played a significant role in the political and cultural life of Florence. Filippo Alberti (1437-1497) was a prominent patron of the arts and a supporter of the Medici family. His son, Benedetto Alberti (1472-1553), was a distinguished scholar and a member of the Platonic Academy of Florence.
The surname Alberti has also been associated with other notable individuals throughout history, such as Giovanni Alberti (1558-1601), an Italian composer and organist during the Renaissance period, and Giorgio Alberti (1723-1758), an Italian mathematician and physicist best known for the Alberti cipher, an early cipher disk used for encryption.
Another prominent figure with the surname Alberti was Raffaello Alberti (1858-1937), an Italian poet, playwright, and literary critic who was a leading figure in the Verist movement. Additionally, Arturo Alberti (1867-1953) was an Italian architect and urban planner who designed several notable buildings in Milan and other cities.

The bar chart below shows how Alberti 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 Alberti 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 Alberti (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
