Origin
The surname "ALAGA" has its origins in the Philippines, and it is thought to have emerged during the Spanish colonial period, which lasted from the 16th to the 19th century. The name is believed to derive from the Tagalog word "alaga," which means "pet" or "favorite."
One of the earliest recorded instances of the surname "ALAGA" can be found in historical documents from the late 18th century, where it appeared as a name used by families living in the provinces of Bulacan and Pampanga. It is possible that the name was initially bestowed upon individuals who were particularly valued or cherished within their communities, perhaps due to their skills, talents, or personal qualities.
During the Spanish colonial era, surnames were often assigned to indigenous Filipinos as a means of assimilation and record-keeping. The practice of adopting Spanish-influenced surnames was encouraged by the colonial authorities, and many Filipinos adopted names that reflected their occupations, physical characteristics, or other personal attributes.
One notable figure bearing the surname "ALAGA" was Francisco Alaga, a prominent landowner and community leader in the town of Malolos, Bulacan, during the late 19th century. He was known for his advocacy of education and his efforts to establish schools in the region.
Another individual with the surname "ALAGA" was Joaquina Alaga, who was born in Pampanga in the early 19th century. She was renowned for her skills as a weaver and her contributions to preserving traditional textile arts in the region.
In the early 20th century, Pedro Alaga, a farmer from Bulacan, gained recognition for his innovative agricultural techniques and his efforts to promote sustainable farming practices in his community.
Additionally, historical records mention a Maria Alaga, who lived in the town of San Miguel, Bulacan, in the late 19th century. She was known for her expertise in traditional herbal medicine and her role as a respected healer in her community.
Juan Alaga, born in Pampanga in the mid-19th century, was a prominent figure in the Philippine Revolution against Spanish colonial rule. He served as a captain in the revolutionary forces and played a significant role in several battles.
While the surname "ALAGA" may have originated as a descriptor or a nickname, it has since become a proud part of the Filipino heritage, reflecting the diverse cultural and linguistic influences that have shaped the country's history.
Demographics
Among Census respondents with the surname Alaga, the largest self-reported group is White at 55.6%. The next largest groups are Black (18.8%) and Asian/Pacific Islander (10.3%).
The bar chart below shows how Alaga 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 Alaga surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
