Origin
The surname Pelaia originated in Italy, with roots tracing back to the medieval period. It is believed to have derived from the Italian word "pelare," which means "to peel" or "to strip." This suggests a possible occupational origin for the name, perhaps related to individuals involved in trades such as skinning animals or preparing fruits and vegetables.
One of the earliest recorded instances of the Pelaia surname can be found in the Codice Diplomatico Barese, a collection of medieval documents from the region of Bari, Puglia, dating back to the 11th century. These records mention individuals bearing the name Pelaia, often in connection with land ownership and transactions.
During the 13th century, the Pelaia name appeared in various documents from the Kingdom of Naples, which encompassed parts of southern Italy. One notable mention is a certain Bartolomeo Pelaia, a merchant and landowner who lived in the city of Salerno around 1250.
In the 15th century, the Pelaia family gained prominence in the town of Monopoli, located in the province of Bari. Records from this time period indicate that members of the family held positions of influence within the local government and ecclesiastical institutions.
One of the most renowned individuals bearing the Pelaia surname was Giacomo Pelaia, a philosopher and theologian who lived in the late 16th century. Born in Lecce, Puglia, in 1558, he authored several works on metaphysics and theology, and served as a professor at the University of Naples.
Another noteworthy figure was Girolamo Pelaia, a 17th-century architect and engineer from Bari. He is credited with designing several churches and fortifications in the region, including the Basilica di San Nicola in Bari, which he worked on between 1625 and 1639.
In the 18th century, the Pelaia name can be found in records from the town of Martina Franca, in the province of Taranto. A prominent member of the family during this time was Giuseppe Pelaia, a lawyer and landowner who lived from 1720 to 1798.
Throughout the centuries, variations of the Pelaia surname have appeared, such as Pelaja, Pelaya, and Pelai. These variants often reflect regional dialects and linguistic influences within different parts of Italy.
While the Pelaia surname is predominantly associated with the southern regions of Italy, particularly Puglia and Campania, it has also spread to other parts of the country and beyond due to migration patterns over the centuries.
Demographics
Among Census respondents with the surname Pelaia, the largest self-reported group is White at 94.4%. The next largest groups are Hispanic (1.9%) and Two or More Races (1.9%).
The bar chart below shows how Pelaia 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 Pelaia 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.
