Users: ronin: US Housing Crisis - Negative Equity Infographic - Zillow

About the map: Negative equity is calculated by matching the estimated value of a home to all outstanding mortgage debt and lines of credit associated with the home, including home equity lines of credit and home equity loans, supplied by TransUnion, a global leader in credit and information management. All personally identifying information ("PII") is removed from the data by TransUnion before delivery to Zillow. The counties and ZIP codes in the highest percentiles (1st, 5th, 10th and 20th percentiles) of negative equity are marked with a badge. Negative equity is calculated for owner-occupied homes with mortgages for more than 800 metros, 2,100 counties, and 22,200 ZIP codes. This map will be updated quarterly. Contact press@zillow.com for additional data points and information including negative equity by state, metro, county, and ZIP code, as well as national data.
