Origin
Meaning and origin of Luongo
The surname Luongo has its origins in Italy, specifically in the region of Campania, which includes the city of Naples and the surrounding areas. The name is believed to have emerged during the Middle Ages, around the 11th or 12th century.
Luongo is derived from the Italian word "lungo," which means "long" or "tall." It is likely that the name was originally a descriptive nickname given to someone who was particularly tall or had a slender physique. This practice of assigning surnames based on physical characteristics was common during that time period.
One of the earliest recorded instances of the name Luongo can be found in a document from the 13th century, which mentions a certain Nicola Luongo residing in the town of Salerno, located in the province of Campania. The name also appears in various medieval records and manuscripts from other parts of the region, such as Naples and the surrounding villages.
In the 14th century, the surname Luongo was documented in the town of Castellammare di Stabia, near Naples. A notable figure from this period was Giacomo Luongo, a merchant and landowner who lived between 1320 and 1395. His name is mentioned in several property records and legal documents from that era.
Another prominent individual bearing the Luongo surname was Antonio Luongo, a renowned painter who lived in Naples during the 16th century (1510-1585). He was known for his religious works and frescoes adorning churches throughout the region.
In the 18th century, a family by the name of Luongo gained prominence in the town of Gragnano, located in the province of Naples. This family owned several pasta factories and contributed significantly to the local economy and culinary traditions.
Pietro Luongo (1760-1834) was a notable figure from this era, known for his involvement in the Neapolitan Republic and his efforts to promote democratic ideals during the turbulent period of the Napoleonic Wars.
Throughout history, the surname Luongo has also been associated with various place names, such as Luongo di Lecco, a small village located in the northern Italian region of Lombardy. Additionally, variations in spelling, such as Lungo or Longhi, have been documented in different regions of Italy.

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

Is this page using the latest Census data?
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 Luongo (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.
