1. Start with Philadelphia scope, not assumed demand
Your service area and your intake operation are related but not identical. Philadelphia city is recorded in Philadelphia County, and the Census estimate covers the municipality for 2020–2024. It does not establish how many people will contact your firm, which practice areas will generate calls, how many staff members you need, or whether callers will prefer a particular language. Those questions belong in an operational review of your actual conversations and follow-up records. For a Philadelphia firm, the first decision is therefore whether calls from this geography should be evaluated together or separated by practice area, referral source, or service territory. That choice affects how useful comparisons will be.
Recommended approach
Bring a clear geographic definition to the consultation: Philadelphia city and Philadelphia County. Then identify the call categories your firm actually wants to compare. Do not use population as a substitute for intake evidence.
