Origin
The surname Teran has its origins in the Iberian Peninsula, specifically in Spain and Portugal. It is believed to have emerged during the medieval period, between the 9th and 15th centuries.
One of the earliest recorded mentions of the surname Teran can be found in the Cartulario de Valpuesta, a medieval manuscript from the 10th century, which documents land ownership and transactions in the Castilian region of Spain. The name is thought to be derived from the Basque word "terrano," meaning "of the land" or "from the land."
During the Reconquista, the centuries-long period of Christian reconquest of the Iberian Peninsula from the Moors, the surname Teran likely came to be associated with individuals who were landowners or held territories in the northern regions of Spain. Some historians believe the name may have been adopted by those who played a role in the expansion of Christian-controlled territories.
In the 13th century, a notable figure bearing the surname Teran was Rodrigo Teran, a Spanish knight and military leader who fought alongside King Alfonso VIII of Castile in the Battle of Las Navas de Tolosa in 1212, a pivotal victory against the Almohad Muslim rulers.
During the 15th century, the surname Teran appears in records from the Kingdom of Aragon, with mentions of individuals such as Juan Teran, a merchant and landowner in the city of Zaragoza.
In the 16th century, as the Spanish Empire expanded its influence across the Atlantic, some individuals with the surname Teran accompanied the conquistadors and settlers to the Americas. One such figure was Pedro de Teran, a Spanish soldier and explorer who participated in the expedition to New Mexico in the late 16th century, led by Juan de Oñate.
As the centuries progressed, the surname Teran spread to other parts of the Spanish-speaking world, including Mexico, where notable figures like José Teran, a 19th-century military officer and politician, and Manuel Teran, a 20th-century artist and muralist, carried the name.
Demographics
Among Census respondents with the surname Teran, the largest self-reported group is Hispanic at 91.6%. The next largest groups are White (7.0%) and Asian/Pacific Islander (0.5%).
The bar chart below shows how Teran 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 Teran 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 Teran (2000, 2010, 2020).
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.
