Origin
The surname CUNANAN is believed to have originated in the Philippines. Its origins can be traced back to the 16th century, when Spanish colonizers arrived in the archipelago. The name is thought to have derived from the Spanish word "cuñado," meaning brother-in-law, or from the word "cuña," meaning wedge or chisel.
During the Spanish colonial period, it was common practice for Filipino families to adopt Spanish surnames as a way of assimilating into the dominant culture. The name CUNANAN may have been given to a family or individual who had a close relationship with a brother-in-law or who worked as a wedge-maker or woodcarver.
One of the earliest recorded instances of the surname CUNANAN can be found in the 1848 Catalogo Alfabetico de Apellidos, a census-like document compiled by the Spanish colonial government in the Philippines. This document listed many Filipino families and their adopted Spanish surnames.
In the late 19th century, a notable figure named Isidro CUNANAN (1848-1919) was a prominent member of the Philippine Revolution against Spanish rule. He served as a general in the revolutionary forces and later held political office under the First Philippine Republic.
Another historical figure with the surname CUNANAN was Filemon CUNANAN (1892-1976), a Filipino lawyer and politician who served as a member of the Philippine House of Representatives and the Philippine Senate in the mid-20th century.
In the field of literature, the name CUNANAN is associated with the Filipino writer and academic, Jose Maria CUNANAN (1901-1983), who authored several books on Philippine history and culture.
Outside of the Philippines, one of the most famous individuals with the surname CUNANAN was Andrew CUNANAN (1969-1997), an American serial killer who gained notoriety for his cross-country murder spree in 1997, which included the killing of fashion designer Gianni Versace.
Another notable bearer of the name was the American artist and sculptor, Cesar CUNANAN (1916-1992), who was known for his abstract and modernist works and was a prominent figure in the New York art scene in the mid-20th century.
Demographics
Among Census respondents with the surname Cunanan, the largest self-reported group is Asian/Pacific Islander at 85.9%. The next largest groups are Two or More Races (5.2%) and White (4.4%).
The bar chart below shows how Cunanan 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 Cunanan surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Cunanan (2000, 2010, 2020).
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.
