Start with the place your firm actually serves
Castaic is recorded as a CDP in Los Angeles County. That is a specific geographic relationship, and it matters when you decide whether your reputation work should focus on Castaic, a wider Los Angeles County service area, or another scope your firm can accurately support. The population estimate describes residents, not households, legal need or prospective clients. It cannot tell you how many people search for a lawyer or how many reviews your firm could earn.
Recommended approach
Map the locations named in your Google Business Profile, website and client communications before starting. Keep Castaic and Los Angeles County distinct in your internal review: decide which matters are genuinely within your service area, which clients may be asked for feedback, and which geographic references belong in public responses. Bosseo can review the geographic coverage and the decisions that need to be made; do not treat the Census estimate as a forecast.
