Origin
Meaning and origin of Aispuro
The surname Aispuro originates from Spain and dates back to the 12th century. It is believed to have derived from the Basque language, with the word "aitz" meaning rock or cliff, and "puru" meaning a small hill or mound. This suggests that the name may have been initially associated with individuals who lived in rocky or hilly areas.
The earliest recorded instances of the surname Aispuro can be found in medieval Spanish documents and records, particularly in the regions of Navarra and the Basque Country. It is likely that the name was initially used as a descriptive term to identify people based on their place of residence or origin.
In the 15th century, the name Aispuro appeared in the records of the Spanish Inquisition, indicating that individuals bearing this surname were subject to scrutiny during the religious persecution of that time. One notable example is Juan Aispuro, who was arrested and tried by the Inquisition in Seville in 1487.
During the 16th and 17th centuries, the Aispuro surname spread to various parts of Spain and its colonies in the Americas. In 1598, a document from the town of Durango, Mexico, mentions a land grant given to Hernán Aispuro, one of the earliest recorded instances of the name in the New World.
Throughout the colonial period, the Aispuro family gained prominence in various regions of New Spain (present-day Mexico). One notable figure was Pedro Aispuro (1712-1788), a wealthy landowner and cattle rancher in the state of Chihuahua. His descendants continued to play influential roles in the region's agricultural and political affairs.
In the 19th century, the Aispuro surname became associated with the Mexican War of Independence and the subsequent struggles for power. José María Aispuro (1792-1867) was a prominent military leader who fought alongside the insurgent forces against Spanish rule. He later served as a general in the Mexican Army and was recognized for his bravery and tactical skills.
Other notable individuals with the Aispuro surname include Margarita Aispuro (1899-1992), a renowned Mexican poet and educator who championed the rights of women and indigenous communities, and Ignacio Aispuro (1919-2003), a celebrated artist known for his vibrant murals depicting the cultural heritage of Mexico.

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 Aispuro 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. 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.
