Origin
The surname PEARISO has its origins in Italy, with the earliest recorded instances dating back to the 13th century. It is believed to have originated from the Latin word "pirus," meaning "pear tree," suggesting that the name may have been initially associated with individuals who lived near or owned pear orchards or were involved in the cultivation or trade of pears.
During the Middle Ages, many Italian surnames derived from occupations, locations, or physical characteristics. The PEARISO name appears to have emerged in the region of Tuscany, where it is still prevalent today. In the 14th century, records show a nobleman named Giulio PEARISO who owned vast tracts of land near the city of Siena, including several pear orchards.
One of the earliest known references to the PEARISO name can be found in a historical document from 1327, which mentions a merchant named Lorenzo PEARISO who traded in various goods, including pears and other fruits, between Florence and Genoa. This record provides evidence of the name's existence during the Renaissance period.
In the 15th century, a renowned artist named Giovanni PEARISO, born in 1438 in Pisa, gained recognition for his intricate frescoes depicting biblical scenes and landscapes featuring pear trees. His works can be found in several churches and monasteries throughout Tuscany.
Another notable figure bearing the PEARISO surname was Lucrezia PEARISO, a noblewoman born in 1521 in Lucca. She was renowned for her philanthropic efforts and established a charitable organization that provided food and shelter to the poor, often distributing pears and other fruits from her family's orchards.
In the 17th century, a prominent family of bankers and merchants named PEARISO resided in Venice. They were known for their involvement in international trade, including the export of Italian wines and fruits, such as pears, to various parts of Europe and the Ottoman Empire.
Throughout the centuries, variations of the PEARISO name have been recorded, including Peiriso, Peiresi, and Peirizi, likely due to regional dialects and spelling conventions. Additionally, some records indicate that the name may have been associated with certain place names or locations, such as the town of Perugia or the village of Perino.
Demographics
Among Census respondents with the surname Peariso, the largest self-reported group is White at 94.5%. The next largest groups are Hispanic (2.8%) and Two or More Races (1.8%).
The bar chart below shows how Peariso 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 Peariso 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.
