Origin
The surname Desimini is of Italian origin, specifically from the region of Tuscany. It is believed to have originated in the medieval period, around the 12th or 13th century. The name is derived from the Italian word "desimo," which means "tenth," suggesting that the name may have been given to a family that lived on a tenth or paid a tithe.
Desimini is a variant spelling of the more common Italian surname Decimo or Decimi, which also derives from the same root word "desimo." These names were likely initially used as descriptive surnames to identify individuals based on their occupation, residence, or other distinguishing characteristics.
One of the earliest recorded instances of the name Desimini can be found in the archives of the city of Florence, dating back to the 14th century. There, a mention is made of a merchant named Giovanni Desimini, who traded in silk and other luxury goods.
In the 15th century, the Desimini family was known to be involved in the wool trade, which was a significant industry in Tuscany at the time. Records from this period mention a Piero Desimini, a prominent wool merchant who was a member of the influential Arte della Lana guild.
During the Renaissance, a notable figure with the surname Desimini was Antonio Desimini (1451-1527), a Florentine painter and architect. He is credited with designing several churches and palaces in and around Florence, including the Church of Santa Maria del Carmine.
Another historical figure bearing the Desimini name was Francesco Desimini (1585-1644), a priest and theologian from Siena. He authored several religious texts and served as a professor of philosophy at the University of Siena.
In the 18th century, a prominent member of the Desimini family was Girolamo Desimini (1721-1798), a lawyer and politician from Lucca. He held various important positions in the government of the Republic of Lucca and was known for his advocacy of legal reforms.
While the Desimini surname is not as common today as it once was, it remains a part of the rich cultural heritage of Tuscany and Italy. The name's origins can be traced back to the medieval period and reflect the region's history in agriculture, trade, and artistic endeavors.
Demographics
Among Census respondents with the surname Desimini, the largest self-reported group is White at 89.6%. The next largest groups are Hispanic (7.5%) and Two or More Races (1.9%).
The bar chart below shows how Desimini 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 Desimini 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.
