Origin
Meaning and origin of Ubina
The surname Ubina originated in Spain during the medieval period. It is believed to have derived from the Spanish word "ubina," which means "olive grove" or "olive orchard." This suggests that the name may have been initially associated with individuals who lived near or owned olive groves.
One of the earliest recorded instances of the name Ubina can be found in the "Libro de la Montería" (Book of the Hunt), a 14th-century Castilian manuscript containing a list of place names and geographical features in Spain. The text mentions "La Ubina," which likely referred to an olive grove or a location with a notable presence of olive trees.
During the 15th century, the name Ubina appeared in various historical documents and records in Spain. For instance, Juan de Ubina, a nobleman from Aragon, was mentioned in a royal decree issued by King Juan II of Aragon in 1458. Additionally, the records of the Spanish Inquisition from the late 15th century list several individuals with the surname Ubina, indicating their presence in various regions of Spain.
In the 16th century, the Ubina surname gained recognition through the exploits of Pedro de Ubina, a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro. Pedro de Ubina was born in Extremadura, Spain, around 1500 and played a significant role in the subjugation of the Inca Empire.
Another notable figure with the surname Ubina was Alonso de Ubina, a Spanish military officer and colonial administrator who served as the governor of the Captaincy General of Guatemala in the late 16th century. He was born in Seville, Spain, around 1530 and played a crucial role in the Spanish colonization of Central America.
In the 17th century, the Ubina surname gained prominence in the arts and literature. One example is the Spanish playwright and poet, Juan de Ubina y Miravete, who was born in Madrid in 1600. He authored several plays and poems that were popular during the Spanish Golden Age of literature.
Throughout its history, the surname Ubina has also been associated with various place names and locations across Spain, such as Ubina de Asturias, a municipality in the principality of Asturias, and Ubina de Guadalajara, a village in the province of Guadalajara. These place names likely derived from the presence of olive groves or orchards in those areas.

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 Ubina 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.
