1. Start with Holtville’s actual service geography
Holtville is recorded as a city in Imperial County, California. If your firm serves Holtville, decide whether your intake process needs to distinguish a Holtville caller from a caller elsewhere in Imperial County or another service area. That is an operational choice, not something population data can answer. The Census estimate of 5,617 people describes Holtville city during the 2020–2024 ACS five-year period; it does not show how many people contact a law firm, which practice areas they ask about, or whether calls arrive during staffed hours.
Recommended approach
Bring your intended service area to the consultation in concrete terms: Holtville, Imperial County, California, and any additional geography your firm actually serves. Then review whether case-type tagging, summaries and follow-up ownership should reflect those boundaries. Do not use the population estimate as a forecast. Use it only to keep the location description precise.
