Origin
Meaning and origin of Acurio
The surname Acurio originated in Spain during the medieval period. It is believed to have derived from the Spanish word "acurio," meaning "shelter" or "refuge." This suggests that the name may have initially been given to someone who lived in or near a shelter or refuge.
One of the earliest recorded instances of the name Acurio can be found in the Becerro General, a medieval manuscript that documented noble families and their coats of arms in Spain. The Becerro General mentions a knight named Rodrigo Acurio, who lived in the 13th century and fought in the Reconquista against the Moors.
In the 15th century, there is a record of a nobleman named Juan de Acurio, who was a prominent figure in the court of King Juan II of Castile. Juan de Acurio served as the King's chamberlain and was known for his loyalty and service to the crown.
During the 16th century, the Acurio family gained prominence in the region of Galicia, in northwestern Spain. One notable figure from this period was Pedro Acurio, a wealthy landowner and patron of the arts, who commissioned several churches and monasteries in the area.
In the 17th century, a branch of the Acurio family migrated to the Spanish colonies in the Americas. One of the earliest recorded individuals with this surname in the New World was Alonso Acurio, who settled in Peru in the early 1600s and became a successful merchant and landowner.
Another notable figure with the surname Acurio was Miguel Acurio, a Spanish soldier and explorer who participated in the conquest of the Philippines in the late 16th century. He played a crucial role in the establishment of Spanish settlements in the archipelago and was rewarded with land grants and titles.
Throughout history, the Acurio surname has been associated with various professions, including military service, landholding, ecclesiastical roles, and mercantile activities. While not as widespread as some other Spanish surnames, the name Acurio has left its mark on various regions of Spain and its former colonial territories.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
