Another prominent figure with the surname Aguila was Diego de Aguila (1560-1628), a Spanish military officer and governor of the Philippines from 1617 to 1624. He played a crucial role in fortifying the Spanish stronghold in the Pacific and defending it against Dutch and Portuguese incursions.

Moving beyond Spain, the surname Aguila also found its way to the Americas, where it became prevalent in various regions. One notable individual was Miguel Aguila (1785-1861), a Venezuelan military leader and politician who played a pivotal role in the Venezuelan War of Independence against Spanish colonial rule.

Demographics
Among Census respondents with the surname Aguila, the largest self-reported group is Hispanic at 81.5%. The next largest groups are Asian/Pacific Islander (12.2%) and White (4.3%).
The bar chart below shows how Aguila 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 Aguila surname at the time of the 2020 Census, not any inherent property of the name itself.
