Origin
Meaning and origin of Erazo
The surname Erazo is believed to have its origins in Spain, specifically in the region of Navarre. It is thought to derive from the Basque word "eratsu," meaning "to seize" or "to grab." This suggests that the name may have been initially given to someone known for their physical strength or assertiveness.
The earliest recorded instances of the name Erazo can be traced back to the 13th century in various medieval documents and records from Navarre. One notable example is the mention of a certain Pedro Erazo in a land grant charter dated 1274, suggesting that individuals bearing this surname held some prominence or landholdings in the region at that time.
As the name spread throughout Spain and its territories, it underwent various spelling variations, such as Eraso, Errazo, and Erasun. These variations were likely influenced by regional dialects and the preferences of local scribes who recorded the name in official documents.
One of the earliest known bearers of the Erazo surname was Juan de Erazo, a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro in the 16th century. Juan de Erazo was born around 1490 in Seville, Spain, and played a significant role in the subjugation of the Inca Empire.
Another notable figure was Sebastián de Erazo, a 16th-century Spanish poet and playwright born in Seville around 1525. His works, including plays and lyrical compositions, were highly regarded during the Spanish Golden Age of literature.
In the 17th century, Diego de Erazo y Zúñiga, born in Seville around 1615, was a prominent Spanish military officer who served in the Spanish Army during the Thirty Years' War. He rose to the rank of Field Marshal and was recognized for his valor and strategic prowess on the battlefield.
The Erazo surname also found its way to the Americas during the Spanish colonial era. One notable bearer was Pedro Erazo, a Spanish settler who established a hacienda in present-day Bolivia in the late 16th century. His descendants continued to play a role in the region's development and governance over subsequent generations.
In the realm of art, Juan Antonio Erazo y Muñoz, born in Seville in 1759, was a renowned Spanish painter known for his religious and allegorical works. His paintings can be found in various churches and museums in Spain and Latin America.
While the Erazo surname has its roots in Spain and the Basque region, it has since spread to other parts of the world, particularly Latin American countries with strong Spanish colonial influences, such as Mexico, Colombia, and Ecuador.

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 Erazo 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.
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.
