Origin
The surname Bonifacio has its roots in the Latin language, derived from the words "bonus" meaning good and "facio" meaning to make or do. It is believed to have originated in Italy during the medieval period, possibly as a nickname or descriptive name given to someone who was considered a good or virtuous person.
One of the earliest recorded instances of the name Bonifacio can be found in the "Codice Diplomatico Longobardo," a collection of medieval legal documents from the Lombard Kingdom in Italy, dating back to the 8th century. The name was also mentioned in various church records and historical chronicles throughout the Middle Ages.
The surname Bonifacio has been associated with several notable figures throughout history. One such individual was Bonifacio Bembo, a Venetian statesman and diplomat who lived in the 15th century (born around 1420, died in 1481). Another was Bonifacio Veronese, an Italian painter and sculptor from the 16th century (born around 1487, died in 1553).
In the 17th century, Bonifacio Calvo was a Spanish theologian and philosopher who made significant contributions to the field of scholastic philosophy (born in 1611, died in 1691). During the same period, Bonifacio Asioli was an Italian composer and music theorist (born in 1769, died in 1832).
Moving into the 19th century, Bonifacio Byrne was an Irish poet and writer who was born in 1861 and died in 1936. He was known for his works that celebrated Irish culture and heritage.
While the surname Bonifacio has its origins in Italy, it has spread to various parts of the world over the centuries. It can be found in Spanish-speaking countries, particularly in Latin America, where it may have evolved into variations such as Bonifacio or Bonifaz. The name has also been present in other European countries, including France, where it may have been influenced by the French spelling "Boniface."
Demographics
Among Census respondents with the surname Bonifacio, the largest self-reported group is Asian/Pacific Islander at 44.4%. The next largest groups are Hispanic (40.9%) and White (11.5%).
The bar chart below shows how Bonifacio 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 Bonifacio 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 Bonifacio (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.
