This dataset focuses on mortgages that are 90 or more days delinquent at the county level across the United States, spanning from January 2008 to September 2019. Mortgages that are 90 or more days delinquent represent loans secured by real estate (typically homes) where borrowers have not made their mortgage payments for at least 90 days or more. This delinquency period is a critical threshold in the mortgage industry and is often an indicator of financial distress for homeowners. Understanding these delinquencies is crucial for assessing the financial health of homeowners and the housing market within various regions, aiding in economic analysis and policy formulation.
