Aggregate HMDA data is available on the CFPB's website, which is a vital resource for monitoring fair mortgage lending practices and housing needs.
Step-by-step explanation:
Aggregate Home Mortgage Disclosure Act (HMDA) data can be found on the Consumer Financial Protection Bureau's (CFPB's) website. The HMDA requires many financial institutions to maintain, report, and publicly disclose information about mortgages. Access to this data is essential for public officials in gauging how financial institutions are serving the housing needs of their communities, and for identifying possible discriminatory lending patterns.
