Origin
The surname Onate originated in Spain during the medieval period. It is derived from the Basque word "ona," meaning "good" or "fertile," and likely referred to a person who lived in a fertile or prosperous area. The name may also be linked to the town of Onate in the Basque region of Spain.
One of the earliest recorded instances of the Onate surname appears in a document from the Monastery of San Millán de la Cogolla in La Rioja, Spain, dating back to the 11th century. This document mentions an individual named Sancho Onate, suggesting the name's existence during that time.
In the 16th century, Juan de Onate, a Spanish explorer and colonial governor, played a significant role in the exploration and settlement of New Mexico. Born in 1550 in Zacatecas, Mexico, he led an expedition to establish the first permanent European settlement in New Mexico in 1598, founding the colony of New Mexico.
Another notable individual with the Onate surname was Gaspar de Onate, a Spanish soldier and explorer who accompanied Juan de Onate on his expedition to New Mexico in the late 16th century. He served as Juan's second-in-command and played a crucial role in the establishment of the colony.
In the 17th century, Francisco de Onate, a Spanish military officer and colonial administrator, served as the governor of the Philippines from 1670 to 1677. He was born in Mexico City in 1629 and played a significant role in the Spanish colonial administration in the Philippines.
During the 19th century, José María Onatre y Pascual, a Spanish writer and journalist, gained recognition for his literary works. Born in 1808 in Valencia, Spain, he wrote several novels and plays that explored social and political themes of his time.
Over the centuries, the Onate surname has undergone various spellings, including Oñate, Onate, Onati, and Onatea, reflecting regional variations and linguistic adaptations. Despite these variations, the name's origins can be traced back to its Basque roots and the fertile regions of Spain where it first emerged.
Demographics
Among Census respondents with the surname Onate, the largest self-reported group is Hispanic at 85.9%. The next largest groups are Asian/Pacific Islander (7.5%) and White (5.7%).
The bar chart below shows how Onate 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 Onate 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 Onate (2000, 2010, 2020).
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.
