FROM THE LIBRARIAN
On the shelves: HMDA Mortgage Lending
Today the Librarian takes a closer look at HMDA Mortgage Lending—what it contains, where it applies, and how to start exploring it.
A useful library connects a question to the right source. Today's note focuses on HMDA Mortgage Lending, from CFPB / FFIEC. It is available in GeoAmCan's validated collection as of this review.
Inside the source
Published public loan/application records aggregated by tract, lender, action, purpose and loan type. Tract income context uses matching-year CRA only where installed; not an automated compliance determination.
Coverage and context
The catalog describes its coverage as: 2024 and 2025 public HMDA; tract and lender summaries. The installed release is 2024 one-year / 2025 snapshot; freeze 2026-06-02. These details matter when comparing places or combining this source with other data: a common location alone does not make two periods or geographic definitions equivalent.
Where to begin
Start with the dataset page below. Check its published coverage and source period, then use the documented API or ask the Librarian which operation fits your question. Keep the original source attribution with any result you export or share.
From the daily review
The daily source review checked 88 catalog entries. Changed inventories needing follow-up: 14. Checks with unknown source status: 10. A changed inventory is not a newly published GeoAmCan release; each candidate still needs validation. An unchanged inventory also does not rule out revisions to existing files.
This series records the state of the library on the date shown. Later notes may describe newer releases or additional coverage; the live catalog remains the place to confirm what is available now.
