Origin
Meaning and origin of Baylen
The surname Baylen originates from Spain, first appearing in the late 15th century. It is believed to be derived from the Andalusian town of Bailén, which was the site of a significant battle during the Peninsular War in 1808. The name may also have connections to the Basque word "baile," meaning "valley" or "glen."
Early records of the Baylen surname can be found in various Spanish archives, including parish registers and municipal documents. One of the earliest known bearers of the name was Pedro de Baylen, a soldier who fought in the Conquest of Granada in the late 1400s.
In the 16th century, the Baylen family established themselves as landowners and merchants in the region of Andalusia. Notable members include Juan Baylen, a wealthy trader who funded the construction of a church in his hometown in the 1570s.
During the 17th century, the Baylens expanded their influence throughout Spain. Francisco Baylen (1612-1683) was a prominent lawyer and judge in Seville, while his cousin, Isabel Baylen (1625-1702), was a renowned poet and patron of the arts.
The Battle of Bailén in 1808, where Spanish forces achieved a decisive victory over the French, further cemented the historical significance of the Baylen name. One of the Spanish commanders, General Francisco Javier Castaños y Baylen (1758-1852), adopted the town's name as part of his own.
Other notable individuals with the Baylen surname include:
1. Miguel Baylen (1892-1968), a Spanish painter and sculptor known for his modernist works.
2. Jaime Baylen (1909-1995), a Mexican actor and director who appeared in numerous films and television shows.
3. María Baylen (1923-2008), a Spanish novelist and playwright whose works explored themes of identity and feminism.
4. Diego Baylen (1947-2015), an Argentine architect and urban planner who designed several landmark buildings in Buenos Aires.
5. Lucía Baylen (b. 1978), a Spanish-born chef and author of several bestselling cookbooks.
While the Baylen surname is not among the most common in Spain today, it continues to hold a significant place in the country's cultural and historical fabric.
Demographics
Ancestry and ethnicity for Baylen
Among Census respondents with the surname Baylen, the largest self-reported group is Asian/Pacific Islander at 56.6%. The next largest groups are White (35.8%) and Two or More Races (4.7%).
The bar chart below shows how Baylen 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 Baylen surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
