The Federal Reserve Bank of New York has developed a series of interactive maps which allow viewers to see information on mortgage delinquencies and foreclosures on a county-by-county basis in a three state region. 

The Regional Mortgage Conditions tool allows a viewer to click through maps showing 60+ and 90+ day delinquencies or loans in the process of foreclosure in New York, New Jersey, and Connecticut and scroll across data for each category to see changes from September 2007 through December 2011.  Analysis for Long Island is also available by zip code. 

"Mortgage delinquencies and foreclosures continue to hinder the strength of the recovery in our district," said Kausar Hamdani, senior vice president of regional and community outreach at the New York Fed. "We are confident this tool will provide relevant and timely analysis to help inform the public, policymakers and community leaders about these ongoing conditions."

The tool, which will be updated and supplemented as more information becomes available, is available here.
