Origin
The surname COLLEA is of Italian origin and can be traced back to the late medieval period in the regions of Lombardy and Veneto. It is believed to have derived from the Latin word "collis," meaning "hill" or "slope," likely referring to a person who lived near or on a hillside.
One of the earliest recorded instances of the name COLLEA can be found in the Codex Diplomaticus Cavensis, a collection of medieval charters and documents from the Monastery of Cava de' Tirreni in Campania, dating back to the 11th century. The name appears in several entries, indicating its presence in the region during that time.
In the 13th century, a notable figure bearing the surname COLLEA was Guglielmo Collea, a renowned jurist and legal scholar from the city of Padua. He authored several influential works on Roman law and was highly regarded in his field.
Another historical figure of note was Francesco Collea, a prominent painter from the Venetian Renaissance period, born in 1498 in Venice. He is best known for his religious frescoes adorning various churches in the region.
During the 15th century, the name COLLEA was also found in the records of the Republic of Genoa, where a family bearing this surname held significant influence in the city's affairs. One member, Giacomo Collea, served as a respected diplomat and ambassador to several European courts.
In the annals of the Spanish Inquisition, the name COLLEA appears in connection with a family of Conversos, or converted Jews, who faced persecution during the 16th century. Antonio Collea, born in 1532 in Seville, was a notable figure in this tragic chapter of history.
Over the centuries, variations of the name COLLEA emerged, such as Collèa, Collia, and Colia, reflecting regional linguistic differences across Italy. Some of these variations were also associated with specific place names, such as the town of Collia in the province of Viterbo.
While the surname COLLEA may not be as widespread as some other Italian names, it has left an indelible mark on history, with notable individuals contributing to various fields, from law and art to diplomacy and literature.
Demographics
Among Census respondents with the surname Collea, the largest self-reported group is White at 85.6%. The next largest groups are Hispanic (10.2%) and Black (1.7%).
The bar chart below shows how Collea 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 Collea 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.
