Origin
The surname Pedro has its origins in Portugal, where it first emerged in the Middle Ages as a patronymic name derived from the given name Pedro, the Portuguese form of Peter. This name ultimately stems from the ancient Greek name Petros, meaning "rock" or "stone."
Pedro was a relatively common surname in medieval Portugal, particularly in the northern regions. It can be traced back to the 12th century, with early recorded instances appearing in various municipal and ecclesiastical records from that era. One notable example is a certain João Pedro, a nobleman mentioned in a charter from the city of Coimbra dated 1187.
Throughout the centuries, the Pedro surname spread across the Portuguese territories and colonies, carried by settlers, explorers, and immigrants. It became particularly prevalent in Brazil, which was colonized by Portugal and received a significant influx of Portuguese settlers from the 16th century onwards.
While the name Pedro itself has biblical origins, referring to the apostle Peter, there are no known direct historical references to this particular surname in major medieval manuscripts or chronicles. However, it is likely that individuals bearing this surname were involved in various historical events and contexts, given its long-standing presence in Portugal and its associated territories.
One of the earliest recorded individuals with the surname Pedro was Álvaro Pedro, a 14th-century Portuguese nobleman and military leader who participated in the Reconquista, the Christian campaign to reclaim the Iberian Peninsula from Moorish rule. He was born around 1320 and played a prominent role in several battles against the Moors.
Another notable figure was João Pedro, a 16th-century Portuguese explorer and navigator who accompanied Ferdinand Magellan on his famous circumnavigation voyage from 1519 to 1522. Though Pedro did not complete the entire journey, he was part of the expedition's crew during its initial stages.
In the 17th century, António Pedro was a respected Portuguese architect and master builder who designed and constructed several churches and other significant buildings in Lisbon and other parts of Portugal. His work left a lasting impact on the architectural landscape of the country.
Moving to the 19th century, José Pedro was a renowned Brazilian poet and journalist who played a pivotal role in the Romantic literary movement in Brazil. Born in 1820, he published several acclaimed works and was actively involved in the country's cultural and intellectual circles.
More recently, in the 20th century, Pedro Almodóvar, the celebrated Spanish filmmaker, has brought international recognition to the surname Pedro. Born in 1949, he is known for his distinctive and provocative cinematic style, and has received numerous accolades, including Academy Awards, for his critically acclaimed films.
Demographics
Among Census respondents with the surname Pedro, the largest self-reported group is Hispanic at 45.2%. The next largest groups are White (31.7%) and Asian/Pacific Islander (9.4%).
The bar chart below shows how Pedro 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 Pedro 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.
