FHFA: National Mortgage Database (NMDB®) Aggregate Statistics

The National Mortgage Database (NMDB®) is a nationally​​ representative five percent sample of residential mortgages in the United States. Publication ​of aggregate data from NMDB is a step toward implementing the statutory requirements of section 1324(c) of the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended by the Housing and Economic Recovery Act of 2008. The statute requires FHFA to conduct a monthly mortgage market survey to collect data on the characteristics of individual mortgages, both Enterprise and​ non-Enterprise, and to make the data a​vailable to the public while protecting the privacy of the borrowers.​<br>Notes:1) All CSV file headers are now standardized as described in the Data Dictionary and Technical Notes and all CSV files are zipped.2) Alternate wide format CSV files are available. The wide format may be more easily opened by MS Excel.***<br>Microdata: Yes<br>Level of Analysis: Groups - (States by) Months; States, National; Local - Metro Area<br>Variables Present: Yes<br>File Layout: .csv<br>Codebook: Yes<br>Methods: Yes<br>Weights (with appropriate documentation): Yes<br>Publications: No<br>Aggregate Data: No
