Origin
The surname Marco is of Italian origin, derived from the Latin name Marcus, meaning "consecrated to the god Mars." It emerged as a personal name during the Roman era and later became a common surname in various regions of Italy.
Marco is believed to have originated in the central and northern parts of Italy, particularly in areas such as Tuscany, Emilia-Romagna, and Lombardy. It is also found in other Italian regions, reflecting the historical migration and settlement patterns of people bearing this name.
In the Middle Ages, the name Marco appears in various historical records and manuscripts, including the famous Florentine tax records known as the "Catasto" from the 14th century. This suggests that the Marco surname was well-established in Italy during this time period.
One of the earliest recorded instances of the Marco surname can be traced back to the 12th century, when a nobleman named Guglielmo Marco was mentioned in a document from the city of Pisa in 1189.
Throughout history, several notable individuals have borne the surname Marco. One of the most famous is Marco Polo, the renowned Venetian merchant and explorer who traveled to Asia and documented his experiences in the book "Il Milione" (The Travels of Marco Polo). He lived from 1254 to 1324.
Another prominent figure was Gian Giacomo Marco, an Italian cartographer and cosmographer who lived in the late 15th century. He is best known for his influential portolan charts and maps, which contributed significantly to the development of cartography during the Age of Exploration.
In the realm of art, the Marco surname is associated with the Italian painter and printmaker Dente di Marco, who was active in the late 15th and early 16th centuries. He is renowned for his engravings and woodcuts, particularly his contributions to the illustration of Dante's Divine Comedy.
During the Renaissance period, the Marco family produced several notable figures, including the architect and sculptor Pietro Marco, who worked in Rome in the 16th century and contributed to the design of various churches and palaces.
In more recent times, the Marco surname has been linked to individuals such as Antonio Marco, an Italian mathematician and physicist from the 18th century, who made significant contributions to the field of optics and the study of light.
Demographics
Among Census respondents with the surname Marco, the largest self-reported group is White at 72.3%. The next largest groups are Hispanic (16.0%) and Asian/Pacific Islander (5.8%).
The bar chart below shows how Marco 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 Marco 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.
