Origin
Meaning and origin of Agustin
The surname Agustin has its origins in the Iberian Peninsula, specifically in what is now Spain and Portugal. It is derived from the Latin name "Augustinus," which itself comes from the Roman name "Augustus." The name Augustus was first used as a title for the Roman emperor Octavian, and later became a common name among Romans.
The earliest recorded instances of the surname Agustin can be traced back to the 9th century in the medieval Kingdoms of León and Castile. At the time, it was often spelled as "Augustin" or "Agostin." The name appeared in various local records and manuscripts from that period, indicating its widespread use among the population.
In the 12th century, the surname Agustin surfaced in the famous Codex Calixtinus, a medieval manuscript detailing the pilgrimage routes to the Cathedral of Santiago de Compostela. This suggests that individuals bearing the name may have been involved in the religious and cultural life of that era.
One of the earliest known bearers of the surname Agustin was Martín Agustin, a Spanish poet and scholar who lived in the 15th century. He was renowned for his contributions to the literary and intellectual circles of his time.
During the 16th century, the name Agustin gained prominence with the birth of Antonio Agustin (1517-1586), a Spanish prelate, diplomat, and renowned scholar of canon law. He served as the Archbishop of Tarragona and played a significant role in the Council of Trent, a pivotal event in the Catholic Reformation.
In the 17th century, the surname was associated with Miguel Agustin, a Spanish painter and engraver who was active in Madrid during the Golden Age of Spanish art. His works are celebrated for their intricate details and depictions of religious scenes.
Another notable figure was José Agustin, a Spanish military officer and explorer who lived in the late 18th century. He was instrumental in the exploration and mapping of the Pacific Northwest region of North America, and his expeditions contributed to the expansion of Spanish colonial influence in the area.
As the centuries passed, the surname Agustin spread throughout the Spanish-speaking world, carried by individuals who immigrated to various regions of the Americas, including Mexico, Central America, and parts of the Caribbean.

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 Agustin surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
