Origin
Meaning and origin of Nazario
The surname Nazario originated in Italy, specifically in the regions of Campania and Lazio. It emerged during the Middle Ages, likely between the 11th and 13th centuries. The name is derived from the Latin "Nazarius," which means "from Nazareth." This connection suggests that the name may have been initially adopted by those who had made a pilgrimage to Nazareth or had a particular devotion to the town where Jesus spent his childhood.
One of the earliest recorded instances of the surname Nazario can be found in a 13th-century document from the town of Sorrento, in the province of Naples, where a certain "Petrus Nazarius" is mentioned. This document provides evidence of the surname's presence in the Campania region during that period.
In the 14th century, the name appears in several historical records from the city of Rome. For example, a "Paulus Nazarius" is listed as a resident of the Rione Monti district in a census from 1347. This suggests that the surname had also gained a foothold in the Lazio region by that time.
During the Renaissance period, the surname Nazario was associated with several notable individuals. One such figure was Giovanni Battista Nazario (1493-1548), a prominent Italian humanist and philosopher who served as a professor at the University of Padua. Another was Bartolomeo Nazario (1501-1571), a renowned architect and sculptor who worked on various projects in Rome and other Italian cities.
In the 17th century, the surname Nazario appeared in connection with several place names in the regions of Campania and Lazio. For instance, there was a small village called "Casale Nazario" near the town of Gaeta, and a rural area known as "Tenuta Nazario" located outside of Rome.
Other notable individuals with the surname Nazario include:
1. Antonio Nazario (1718-1793), an Italian painter and engraver from Naples.
2. Giacomo Nazario (1801-1879), an Italian composer and music teacher who worked in Naples.
3. Girolamo Nazario (1825-1901), an Italian politician and lawyer from the province of Caserta.
4. Pio Nazario (1877-1942), an Italian sculptor and artist from Rome.
5. Umberto Nazario (1904-1983), an Italian actor and theater director who was born in Campobasso.
While the surname Nazario has a long and rich history in Italy, it has also spread to other parts of the world through immigration. However, this detailed report focuses solely on the origins and historical significance of the surname within the Italian context.

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 Nazario surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Nazario (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
