1. Start with Hillsdale’s actual service area, not a generic market label
Hillsdale is a municipality in Bergen County, New Jersey. The 2020–2024 ACS five-year population estimate records 10,144 residents, with a margin of error of 24. For attribution, the practical implication is narrower: your firm should decide whether Hillsdale is one distinct service area in your reporting or part of a broader Bergen County structure. A location label alone cannot tell you which pages, referrals or campaigns produce qualified inquiries.
Recommended approach
Before evaluating performance, define the geographic fields you want to compare. Keep Hillsdale, Bergen County and any wider New Jersey service area distinct where that distinction matters to intake or budgeting.
