The similar direction is not a causal finding or a universal city premium. County and city boundaries contain different places and housing mixes. Zillow and Realtor.com also measure different populations.

Method and limits
Values were transcribed from the named public pages on 2026-09-29. Derived differences use the displayed values without hidden precision. No provider supplied a record-level sample size on the cited city page, so sample size is recorded as not supplied. The table is a dated comparison, not a property valuation, forecast or complete market census. Historical values may be revised by the providers.
