* No Official Census Data: While there are censuses in the Philippines, they generally focus on primary language spoken, not the frequency of use.
* Linguistic Diversity: Caloocan, like many urban areas, has a diverse population. While Tagalog is the national language and widely understood, residents might also speak English, Filipino, or other regional languages.
* Language Use Varies: Even if someone is fluent in Tagalog, they might not use it exclusively in all situations.
However, we can make some educated guesses:
* Tagalog is Dominant: Caloocan is located in Metro Manila, where Tagalog is the primary language.
* High Urbanization: Urban areas tend to have more exposure to the national language, making it likely a high percentage of residents understand and speak Tagalog.
It's safe to assume a very large majority of Caloocan residents speak Tagalog, but an exact percentage is not available.
