Origin
The surname Pacarro originated in Italy during the medieval period. It is believed to have derived from the Latin word 'pacare,' which means 'to pacify' or 'to calm.' This suggests that the name may have been given to someone with a calming or peaceful demeanor.
One of the earliest recorded instances of the name Pacarro can be found in a 12th-century manuscript from the city of Florence. In this document, a certain Giovanni Pacarro is mentioned as a landowner in the region.
During the 13th century, the name Pacarro appeared in several records from the Italian city-states of Genoa and Pisa. These records often referred to merchants and traders with this surname, indicating that the Pacarro family may have been involved in commercial activities.
In the 14th century, a notable figure named Niccolò Pacarro (1298-1372) was a prominent lawyer and statesman in the Republic of Venice. He served as a legal advisor to the Doge and played a crucial role in the drafting of several important laws and treaties.
The name Pacarro can also be found in some historical documents from the Renaissance period. For instance, a certain Girolamo Pacarro (1452-1524) was a renowned painter and fresco artist from the city of Siena. He is best known for his works adorning the interiors of various churches and palaces in Tuscany.
Another notable individual with the surname Pacarro was Antonio Pacarro (1610-1679), a celebrated composer and musician from Naples. He was highly regarded for his contributions to the development of the Baroque music style and worked as a court composer for several noble families.
While the name Pacarro is not as common today as it once was, it remains a part of Italy's rich cultural heritage, with its roots stretching back to the Middle Ages and the Renaissance.
Demographics
Among Census respondents with the surname Pacarro, the largest self-reported group is Asian/Pacific Islander at 49.6%. The next largest groups are Two or More Races (22.2%) and Hispanic (12.8%).
The bar chart below shows how Pacarro 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 Pacarro 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.
