Origin
The surname Bailon is of Spanish origin, tracing its roots back to the medieval period in the Iberian Peninsula. It is believed to have derived from the Spanish word "baile," meaning "dance" or "ballet." This suggests that the name may have been initially associated with individuals involved in the performing arts or those who were known for their dancing skills.
One of the earliest recorded instances of the name Bailon can be found in the 13th century, when a nobleman named Gonzalo Bailon was mentioned in the Cantigas de Santa María, a collection of poems and songs written during the reign of King Alfonso X of Castile (1221-1284). This literary reference provides evidence of the name's existence during that era.
In the 15th century, the name appeared in a legal document from the city of Seville, where a certain Juan Bailon was listed as a witness to a property transaction. This record indicates that the name had spread beyond its initial regional boundaries and was present in various parts of Spain.
During the 16th century, one notable figure bearing the surname Bailon was Pascual Bailon, a Spanish friar and mystic who lived from 1540 to 1592. He was known for his piety and devotion to the Franciscan Order and was later canonized by the Catholic Church in 1690.
Another prominent individual with the surname Bailon was Diego Bailon, a 17th-century Spanish playwright and poet. Born in Seville in 1602, he gained recognition for his contributions to the Spanish Golden Age theater, producing numerous plays and literary works.
In the 18th century, the name Bailon was associated with Manuel Bailon, a Spanish military officer who participated in the Napoleonic Wars. He played a significant role in the defense of Cádiz against the French forces during the Peninsular War (1808-1814).
The 19th century saw the birth of Emilio Bailon, a Spanish painter and artist known for his landscapes and portraiture. He was born in Madrid in 1828 and gained recognition for his works, which were exhibited in various galleries across Spain.
Throughout its history, the surname Bailon has been linked to various locations and place names within Spain, such as Bailon de Calatrava, a municipality in the province of Ciudad Real, and Bailon de Rute, a village in the province of Córdoba. These place names may have contributed to the further spread and adoption of the surname in different regions.
Demographics
Among Census respondents with the surname Bailon, the largest self-reported group is Hispanic at 87.2%. The next largest groups are Asian/Pacific Islander (4.3%) and White (3.7%).
The bar chart below shows how Bailon 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 Bailon 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.
