Origin
Meaning and origin of Cacdac
The surname CACDAC has its origins in the Philippines. It is believed to have derived from the Visayan word "cacdac," which means "to strike with force" or "to pound repeatedly." This suggests that the name may have originated as a descriptive term for an occupation or a personal characteristic.
One of the earliest recorded instances of the CACDAC surname can be found in the 18th century, when a man named Juan CACDAC was mentioned in a parish record from the town of Romblon, located in the central Philippines. This suggests that the name may have been more prevalent in the Visayan-speaking regions of the archipelago.
In the 19th century, the CACDAC surname gained recognition through the works of Gregorio CACDAC, a prominent Filipino writer and poet who lived from 1830 to 1892. He was known for his contributions to the development of Filipino literature and his advocacy for the use of the Visayan language in literary works.
Another notable figure with the CACDAC surname was Teodoro CACDAC, a Filipino revolutionary who fought against Spanish colonial rule in the late 19th century. He was born in 1870 and played a significant role in the Philippine Revolution, serving as a military leader in the Visayan region.
In the 20th century, the CACDAC surname continued to be represented by notable individuals, such as Emilio CACDAC, a renowned Filipino painter who lived from 1905 to 1988. His works were celebrated for their vibrant colors and depictions of Filipino culture and rural landscapes.
Another notable figure was Maria CACDAC, a Filipino activist and educator who was born in 1920. She dedicated her life to promoting education and advocating for women's rights in the Philippines, establishing several schools and organizations focused on empowering women and girls.
While the CACDAC surname may have originated from a specific region in the Philippines, it has since spread throughout the country and perhaps even to other parts of the world due to migration and cultural exchange. However, its roots can be traced back to the Visayan language and the rich cultural heritage of the Philippine archipelago.

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 Cacdac surname at the time of the 2020 Census, not any inherent property of the name itself.
