Origin
The surname Carrero has its origins in Spain, tracing back to the early medieval period around the 11th century. It is believed to have derived from the Latin word "carraria," which referred to a road or path, suggesting that the name may have been originally associated with a person who lived near a major road or was a traveler.
One of the earliest recorded instances of the Carrero surname can be found in the Becerro de las Behetrías de Castilla, a historical document from the 14th century that documented land ownership and population records in Castile. This suggests that the name was established and in use among the Spanish nobility during that time.
In the 15th century, the Carrero family played a prominent role in Spanish history. Juan Carrero de Zamora (c. 1435-1494) was a Spanish prelate who served as the Archbishop of Toledo and held significant political influence during the reign of Queen Isabella I of Castile.
Another notable figure with the Carrero surname was Pedro Carrero de Tordesillas (c. 1500-1572), a Spanish military leader and conquistador who participated in the conquest of Peru alongside Francisco Pizarro. He was granted extensive land holdings and became one of the wealthiest men in the Spanish colonies.
In the 17th century, Gaspar Carrero de Guzmán (1607-1681) was a Spanish nobleman and politician who served as the Viceroy of New Spain (present-day Mexico) from 1670 to 1676. His tenure was marked by significant reforms in the administration of the Spanish colonies in the Americas.
The Carrero surname can also be traced to the Canary Islands, where it is believed to have been introduced by settlers from Spain during the 15th and 16th centuries. One notable figure from this region was Sebastián Carrero (c. 1550-1620), a Spanish navigator and explorer who was instrumental in the early colonization efforts of the Canary Islands.
While the Carrero surname has its roots in Spain, it has since spread to other parts of the world, particularly to Latin American countries, due to Spanish colonization and migration. The name has also undergone various spelling variations over time, such as Carrera, Carreras, and Carreiro.
Demographics
Among Census respondents with the surname Carrero, the largest self-reported group is Hispanic at 89.0%. The next largest groups are White (9.5%) and Black (0.8%).
The bar chart below shows how Carrero 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 Carrero 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.
