Origin
Meaning and origin of Segundo
The surname "Segundo" originates from the Spanish language and has its roots in Spain during the medieval period. It is believed to have derived from the Latin word "secundus," which means "second" or "following."
The earliest recorded instances of the surname Segundo can be traced back to the 12th century in various parts of Spain, particularly in regions like Andalusia, Aragon, and Castile. It is speculated that the name was initially used to distinguish between individuals with the same first name, such as a father and son or siblings.
In the 13th century, the surname Segundo appeared in several historical documents, including tax records and land registries from various Spanish municipalities. One notable mention is found in the Cartulario de San Millán de la Cogolla, a medieval cartulary from the Monastery of San Millán de la Cogolla in La Rioja, Spain.
During the 15th century, the surname Segundo gained prominence in Spain, with several notable figures bearing the name. Juan Segundo (1456-1521), a Spanish poet and humanist from Andalusia, was one of the most renowned individuals with this surname during the Renaissance period.
As the Spanish Empire expanded, the surname Segundo spread to other parts of the world, particularly to Spanish colonies in the Americas. One of the earliest recorded instances of the surname Segundo in the Americas is found in the baptismal records of the Cathedral of Santo Domingo in the Dominican Republic, dating back to the late 16th century.
Other notable individuals with the surname Segundo include:
1. Pedro Segundo (1628-1693), a Spanish painter and engraver from Madrid.
2. Juan Segundo de Isla (1703-1784), a Spanish satirist and essayist from Galicia.
3. Mateo Segundo Gálvez (1770-1847), a Spanish military officer and colonial administrator in Venezuela.
4. Jaime Segundo (1892-1967), a Chilean politician and lawyer who served as President of the Chamber of Deputies.
5. Manuel Segundo Sánchez (1899-1957), a Mexican composer and musician renowned for his contributions to the mariachi genre.
The surname Segundo has maintained its presence throughout history, with various spellings and variations emerging in different regions, such as Segondo, Segundu, and Segunt. However, the core meaning and origin of the name remain rooted in its Spanish heritage and the concept of being "second" or "following."

The bar chart below shows how Segundo 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 Segundo surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Segundo (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
