Origin
The surname Ippoliti originated in Italy, and it is derived from the Italian version of the Greek name Hippolytus, which means "one who unbinds horses." This name can be traced back to the late 13th century in various parts of Italy, particularly in the regions of Tuscany, Umbria, and Lazio.
The earliest recorded instance of the Ippoliti surname can be found in historical documents from the city of Perugia, Umbria, dating back to the late 1200s. These records include mentions of individuals with the surname Ippoliti who held positions of prominence within the local community.
During the Renaissance period, the Ippoliti family gained significant influence and recognition in the city of Florence, Tuscany. One notable member was Ippolito Ippoliti (1504-1561), a renowned humanist scholar and poet who was closely associated with the Medici family.
In the 17th century, the Ippoliti surname appeared in various ecclesiastical records, indicating that members of the family had entered the Catholic clergy. One such individual was Monsignor Girolamo Ippoliti (1601-1672), a prominent ecclesiastic who served as the Vicar General of the Diocese of Rome during the papacy of Pope Urban VIII.
Another notable figure was Pietro Ippoliti (1702-1777), an Italian painter and architect from the town of Viterbo, Lazio. He is renowned for his works in the Baroque and Rococo styles, and his contributions can be seen in various churches and palaces throughout central Italy.
In the 19th century, the Ippoliti surname gained international recognition through the works of Giuseppe Ippoliti (1819-1883), an Italian botanist and explorer. He is best known for his extensive research on the flora of Central America and his contributions to the study of Mexican plants.
Throughout history, the surname Ippoliti has been found in various spellings, such as Ippolitti, Ippolito, and Hippoliti, reflecting the regional variations and linguistic influences within Italy. Additionally, the name has been associated with certain place names, such as the town of Ippoliti in the province of Frosinone, Lazio, which may have contributed to the origin and spread of the surname.
Demographics
Among Census respondents with the surname Ippoliti, the largest self-reported group is White at 89.8%. The next largest groups are Hispanic (6.2%) and Two or More Races (2.0%).
The bar chart below shows how Ippoliti 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 Ippoliti 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.
