Origin
The surname "NIGRI" is of Italian origin and can be traced back to the medieval period. It is derived from the Latin word "niger," meaning "black," and was likely originally a nickname or descriptive name given to someone with dark hair or complexion.
The earliest known instances of the name can be found in various Italian documents from the 13th and 14th centuries, particularly in regions such as Tuscany, Emilia-Romagna, and Lombardy. Historical records suggest that the name was prominent among families in cities like Florence, Bologna, and Milan during this time.
In the 14th century, the name NIGRI appeared in the Florentine Catasto of 1427, a census record of the citizens of Florence. One notable individual from this period was Bartolomeo NIGRI, a Florentine merchant and banker who lived from around 1380 to 1450.
During the Renaissance era, the name NIGRI was associated with several prominent figures in the arts and sciences. Pietro NIGRI (1472-1554) was a renowned Italian mathematician and astronomer from Venice, known for his contributions to the study of trigonometry and his work on the reform of the Julian calendar.
Another notable bearer of the name was Gerolamo NIGRI (1522-1591), an Italian philosopher and theologian from Milan. He was a prominent figure in the Catholic Reformation and served as a counselor to Pope Pius V.
In the 18th century, the NIGRI surname was found among families in various parts of Italy, including the regions of Piedmont and Veneto. One example is Giovanni Battista NIGRI (1724-1801), an Italian architect and engineer from Turin, who was known for his work on several notable buildings and infrastructure projects in the city.
Another significant figure was Giuseppe NIGRI (1728-1806), an Italian composer and violinist from Venice. He was renowned for his contributions to the development of the Venetian school of violin playing and his compositions for the instrument.
Throughout history, the NIGRI surname has been associated with various occupations, including merchants, bankers, scholars, artists, and professionals in various fields. While it originated as a descriptive name, it has since become a well-established Italian surname with a rich historical legacy.
Demographics
Among Census respondents with the surname Nigri, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (2.6%) and Two or More Races (2.6%).
The bar chart below shows how Nigri 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 Nigri 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.
