Sources and definitions

Sale-price and property-type histories use Redfin where available. Redfin observations cover rolling three-month periods. Zillow Research supplies monthly home-value and rent indices and additional market series. Provider selection is shown in the chart details. Each metric retains its own reporting date.

Sale price per square foot describes completed sales with reported floor area; it is not a listing-price measure. Active listings count listings active during the reporting period. Home values and rents are typical-value indices, not sale-price or rent medians. ZIP map boundaries are Census ZCTAs and may differ from provider regions. Related ZIP associations do not imply containment within city boundaries.
