1. Start with the actual Old Tappan footprint
The U.S. Census Bureau records Old Tappan borough as a municipality in Bergen County, New Jersey. Its 2020–2024 ACS 5-year population estimate is 6,008, with a margin of error of 23. For your firm, the useful geographic question is not whether that number predicts clients. It does not. The question is whether Old Tappan belongs inside the area you genuinely serve and can describe accurately. A firm serving Bergen County may consider Old Tappan alongside other municipalities in the county. A firm with a narrower service area may decide that a single Old Tappan page is more appropriate than broad coverage. Keep the municipality, county, metropolitan area, New Jersey, households, and individuals distinct when defining scope.
Recommended approach
Confirm that Old Tappan and Bergen County match your accepted matters, court or administrative reach, consultation area, and existing service commitments. Treat the Census geography as a boundary reference, then make the footprint decision from your practice—not from population alone.
