Origin
The surname Pesaresi originated in Italy, specifically in the Marche region, during the medieval period. It is derived from the Italian word "pesaro," which refers to the coastal city of Pesaro located in the province of Pesaro and Urbino.
The name is believed to have its roots in the Latin word "pisaurum," which was the ancient Roman name for the city of Pesaro. This suggests that the surname Pesaresi may have initially been used to identify individuals who either lived in or had some connection to the city of Pesaro.
Historical records indicate that variations of the name, such as "Pesarese" and "Pisaurensis," can be found in documents dating back to the 13th and 14th centuries. These early references often referred to individuals born or residing in the city of Pesaro.
One of the earliest recorded instances of the surname Pesaresi can be traced back to a document from 1472, which mentions a certain "Giovanni Pesaresi" who was a merchant in the city of Pesaro. This document provides valuable insight into the use of the surname during that time period.
In the 16th century, the name Pesaresi gained further prominence with the birth of Bartolomeo Pesaresi (1516-1587), a renowned Italian painter and architect from Pesaro. His works adorned several churches and buildings in his hometown and surrounding areas.
Another notable figure with the surname Pesaresi was Alessandro Pesaresi (1663-1728), an Italian composer and music theorist. He was born in Pesaro and is best known for his contributions to the development of the solo cantata genre.
During the 18th century, the name Pesaresi was associated with the Italian mathematician and astronomer Giovanni Pesaresi (1725-1801). He was born in Pesaro and made significant contributions to the study of celestial mechanics and the calculation of planetary orbits.
In the 19th century, the surname Pesaresi gained international recognition with the birth of Raffaele Pesaresi (1835-1893), an Italian painter and engraver. His works were exhibited in various art galleries across Europe and are now part of several museum collections.
Throughout its history, the surname Pesaresi has maintained a strong connection to the city of Pesaro, reflecting the geographic origins of this name. While the name has likely spread beyond its initial confines, its roots remain firmly planted in the Marche region of Italy.
Demographics
Among Census respondents with the surname Pesaresi, the largest self-reported group is White at 81.4%. The next largest groups are Hispanic (15.7%) and Black (1.0%).
The bar chart below shows how Pesaresi 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 Pesaresi 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.
