Origin
The surname Olivarez is of Spanish origin, originating from the Iberian Peninsula in the Middle Ages. It is derived from the Spanish word "oliva," meaning "olive," and likely referred to someone who cultivated or traded olives.
The earliest recorded instances of the Olivarez surname date back to the 13th century in various regions of Spain, particularly in the areas around the cities of Seville and Cordoba, where olive cultivation was prevalent. It is possible that the name may have been initially attributed to individuals or families involved in the olive oil industry.
In the 14th century, records show the Olivarez name appearing in the "Libro Becerro de las Behetrías de Castilla," a medieval manuscript that documented land ownership and taxation in the Kingdom of Castile. This suggests that individuals bearing this surname held landholdings or were associated with estates during that time.
One of the earliest known individuals with the Olivarez surname was Juan de Olivarez, a 15th-century Spanish soldier who fought in the Reconquista, the campaign to expel the Moors from the Iberian Peninsula. He was born around 1420 and served under the command of King Ferdinand II of Aragon and Queen Isabella I of Castile.
During the 16th century, the Olivarez surname gained prominence in Spain and its colonies. Gaspar de Olivarez, born in 1587, was a Spanish nobleman and statesman who served as the chief minister to King Philip IV of Spain. He played a significant role in shaping Spanish policy during the Thirty Years' War and the Golden Age of Spanish literature.
In the 17th century, Alonso de Olivarez, born in 1612, was a Spanish explorer and conquistador who led expeditions into modern-day Texas and New Mexico, establishing several missions and settlements in the region.
Another notable individual was María de Olivarez, a 16th-century Spanish writer and poet who was part of the literary circle in Granada. Her collection of poetry, published in 1582, was widely acclaimed and contributed to the development of Spanish Renaissance literature.
As the Spanish Empire expanded, the Olivarez surname spread to various parts of the Americas, particularly in Mexico, where it is still prevalent today. Over time, the name also underwent slight variations in spelling, such as Olivares and Olivárez, but the core meaning and origin remained the same.
Demographics
Among Census respondents with the surname Olivarez, the largest self-reported group is Hispanic at 90.3%. The next largest groups are White (7.6%) and Asian/Pacific Islander (1.0%).
The bar chart below shows how Olivarez 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 Olivarez 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.
