Origin
The surname URIONA has its origins in Bolivia, with the earliest records dating back to the 16th century. It is believed to have derived from the Aymara language, spoken by indigenous communities in the Andes region. The name may have roots in the word "urion," which refers to a type of indigenous plant or crop.
During the Spanish colonial period, many indigenous Bolivians adopted Spanish surnames as part of the process of assimilation and conversion to Christianity. URIONA likely emerged as a Hispanicized version of an Aymara name or word, adapted to fit the Spanish naming conventions.
One of the earliest known references to the surname URIONA can be found in the records of the colonial administration in La Paz, Bolivia, from the late 1500s. These records document individuals with this surname living in the region at that time.
In the 17th century, a notable figure bearing the name URIONA was Juan de Uriona, a prominent landowner and farmer in the Cochabamba region of Bolivia. He was known for his contributions to the local agriculture and played a role in the development of the area's farming communities.
Another significant historical figure was María Uriona, a renowned healer and midwife who lived in the late 18th century in the town of Sucre, Bolivia. She was highly respected for her knowledge of traditional medicine and her role in supporting the local community.
In the 19th century, José Uriona was a influential political figure in Bolivia. He served as a member of the Constituent Assembly and was instrumental in shaping the country's early political structures after independence from Spain.
One of the most famous bearers of the URIONA surname was Matilde Uriona, a celebrated Bolivian poet and writer who lived from 1892 to 1975. Her works explored themes of identity, culture, and the experiences of indigenous communities in Bolivia. She is considered a pioneering figure in Bolivian literature.
Throughout its history, the URIONA surname has been associated with various areas and regions within Bolivia, particularly in the central and western parts of the country, where Aymara communities have traditionally resided.
Demographics
Among Census respondents with the surname Uriona, the largest self-reported group is Hispanic at 68.1%. The next largest groups are White (30.1%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Uriona 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 Uriona 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.
