Origin
Meaning and origin of Casado
The surname Casado is of Spanish origin, deriving from the Spanish word "casado" which means "married" or "wedded." It likely originated as a descriptive surname given to someone who was married, or perhaps to distinguish between two individuals with the same first name, one being married and the other unmarried.
The earliest recorded instances of the Casado surname can be traced back to the 13th century in various regions of Spain, particularly in areas such as Castile, Aragon, and Andalusia. The name was also found in historical records and documents from this period, although specific mentions are scarce due to the limited preservation of records from that time.
One notable early bearer of the Casado surname was Pedro Casado, a Spanish military commander who served under King Alfonso XI of Castile in the 14th century. He played a crucial role in the Reconquista, the campaign to drive out the Moors from the Iberian Peninsula.
In the 15th century, the Casado surname appeared in various Spanish towns and villages, often associated with local landowners or prominent families. For instance, the village of Casado de Pinares in the province of Avila is believed to have taken its name from a Casado family that owned land in the area.
During the age of Spanish exploration and colonization, several individuals with the Casado surname participated in the voyages and expeditions to the Americas. Juan Casado was a sailor who accompanied Christopher Columbus on his second voyage to the New World in 1493.
In the 17th century, Francisco Casado was a renowned Spanish painter and engraver known for his religious works and portraits. He was born in Madrid in 1619 and died in 1682.
As the Spanish Empire expanded, the Casado surname also spread to various colonies and territories. One notable figure was José Casado del Alisal, a Spanish military officer and colonial administrator who served as the Governor of the Philippine Islands from 1764 to 1766.
Throughout history, the Casado surname has been carried by individuals from various walks of life, including artists, soldiers, explorers, and landowners. While its origins can be traced back to the Iberian Peninsula, the name has since been dispersed across the globe, reflecting the far-reaching influence of Spanish culture and history.

The bar chart below shows how Casado 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 Casado surname at the time of the 2020 Census, not any inherent property of the name itself.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
