Origin
Meaning and origin of Coreas
The surname Coreas has its origins in Portugal, dating back to the 15th century. It is believed to be derived from the Portuguese word "coroa," which means "crown." This suggests that the name may have been associated with individuals who held positions of nobility or authority within the Portuguese monarchy.
In the early days, the name was primarily concentrated in the regions of Lisbon and the surrounding areas. Historical records from the 16th and 17th centuries mention individuals bearing the name Coreas, including several who served in the Portuguese military during the Age of Exploration.
One notable figure was João Coreas, a Portuguese navigator who participated in several expeditions to the Americas and Africa in the late 15th century. Another was Diogo Coreas, a soldier who fought alongside Vasco da Gama in the conquest of India in the early 16th century.
As the Portuguese empire expanded, the name Coreas spread to other parts of the world, particularly to the colonies in Africa and South America. In Brazil, for instance, there are records of individuals with the surname Coreas dating back to the 17th century.
In the 18th century, the name Coreas also appeared in various historical documents in Spain, possibly due to the close ties between the Portuguese and Spanish monarchies at the time. One notable figure from this period was Pedro Coreas, a Spanish military officer who served in the Spanish colonies in the Americas.
As the centuries passed, the name Coreas continued to spread and evolve, with variations in spelling and pronunciation emerging in different regions. Some examples of notable individuals with this surname include:
1. Manuel Coreas (1828-1898), a Nicaraguan politician and diplomat who served as President of Nicaragua from 1891 to 1893.
2. Antonio Coreas (1878-1945), a Salvadoran politician and lawyer who served as President of El Salvador from 1923 to 1927.
3. Maria Coreas (1890-1976), a Spanish painter and sculptor known for her works depicting scenes from Spanish folklore and rural life.
4. José Coreas (1912-1998), a Honduran writer and poet who was a prominent figure in the Latin American literary movement of the 20th century.
5. Alejandro Coreas (born 1962), a Salvadoran-American artist and sculptor whose works have been exhibited in galleries around the world.
While the surname Coreas may have originated from a specific region and historical context, it has since spread and taken on new meanings and associations in different parts of the world, reflecting the rich diversity and cultural exchange that has shaped human history.

The bar chart below shows how Coreas 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 Coreas 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 Coreas (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.
