Origin
Meaning and origin of Decampo
The surname DECAMPO is of Spanish origin, tracing its roots back to the Iberian Peninsula during the medieval period. It is believed to have evolved from the Spanish phrase "del campo," which translates to "of the field" or "from the countryside."
This surname likely originated as a way to distinguish individuals who hailed from rural areas or agricultural regions. In the early days, surnames were often derived from physical characteristics, occupations, or places of origin, and DECAMPO falls into the latter category.
One of the earliest recorded instances of the surname DECAMPO can be found in the Repartimiento de Sevilla, a medieval document from the 13th century that recorded land grants and property distributions in the region of Seville following the Reconquista. This document mentions individuals with variations of the surname, such as De Campo and Del Campo.
During the 15th and 16th centuries, the DECAMPO surname gained prominence in various parts of Spain, particularly in regions like Andalusia and Castile. Notable individuals from this era include Juan de Campo (c. 1480-1550), a Spanish soldier and conquistador who participated in the conquest of Mexico alongside Hernán Cortés.
As the Spanish Empire expanded its reach across the Atlantic, the DECAMPO surname began to appear in the Americas. One notable figure was Pedro de Campo (c. 1520-1590), a Spanish explorer and navigator who played a significant role in the exploration and settlement of Cuba and Florida.
In the 17th century, the surname DECAMPO found its way to the Philippines, where it was adopted by individuals of Spanish descent. One prominent figure from this period was Diego de Campo (1619-1682), a Spanish missionary and linguist who contributed to the study of Philippine languages and cultures.
Another notable individual with the DECAMPO surname was Juan de Campo (1628-1708), a Spanish military officer and colonial administrator who served as the governor of Florida and Cuba in the late 17th century.
As the centuries passed, the DECAMPO surname continued to spread across various regions, with individuals bearing this name making their mark in various fields, from politics and military to arts and sciences.

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