Origin
The surname COLCOL originated in the Piedmont region of northwestern Italy during the 13th century. It is believed to be derived from the Latin word "collis," meaning hill or hillock, suggesting that the name's bearers may have resided in a hilly area or near a specific hill.
One of the earliest recorded instances of the name COLCOL can be found in the Codex Astensis, a 13th-century cartulary from the city of Asti in Piedmont. This document mentions a certain Guglielmo COLCOL, who was likely a landowner or a prominent figure in the region.
In the 14th century, the surname appears in various records from the nearby town of Chieri, where a family by the name of COLCOL held significant influence. Notably, Lorenzo COLCOL, born in 1328, was a respected merchant and banker who played a crucial role in the town's economic affairs.
The COLCOL name also has a connection to the Italian Renaissance. Girolamo COLCOL, born in 1457 in Turin, was a renowned painter and fresco artist whose works adorned several churches and palaces in northern Italy. His legacy as a skilled artist has been documented in various art historical records.
During the 16th century, the COLCOL surname gained prominence in the city of Genoa, where a branch of the family had settled. Luca COLCOL, born in 1521, was a prominent shipbuilder and naval architect who contributed significantly to the development of the Genoese maritime industry.
As the COLCOL family spread throughout Italy and beyond, variations in spelling emerged, including COLCOLO, COLCOLLI, and COLCOLLINI. These variations often reflected regional dialects or adaptations to different languages and cultures.
While the COLCOL surname is not among the most common in Italy today, it has left an enduring mark on the country's history, with numerous notable individuals bearing this name over the centuries, from merchants and bankers to artists and naval architects.
Demographics
Among Census respondents with the surname Colcol, the largest self-reported group is Asian/Pacific Islander at 78.6%. The next largest groups are Hispanic (15.4%) and Two or More Races (3.4%).
The bar chart below shows how Colcol 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 Colcol 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 Colcol (2000, 2010, 2020).
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.
