Pinning to a specific mirror

All five DOIs resolve to the same conceptual dataset, but pin to whichever registry your discipline expects:

Mirror	DOI	Use when
Figshare	10.6084/m9.figshare.32332290	General-purpose academic citation
Zenodo (CERN)	10.5281/zenodo.20302283	European institutional research; FAIR-data compliance audits
OSF	10.17605/OSF.IO/PUMKT	Preregistered studies and reproducibility-focused workflows
Kaggle	10.34740/kaggle/dsv/16356447	Notebook environments; ML competitions
Mendeley	10.17632/jsnwhy6vjn.1	Elsevier-adjacent submissions

Citing the primary source too

The dataset is a mirror, not the primary source. When citing in scholarly work, you should cite the underlying publisher alongside the CalcFi Open Data DOI. The relevant publisher URL is in the # Source: and # Primary URL: comment lines of each CSV, and in the per-series datapackage.json. For example, when citing the 30-year mortgage rate series, cite both:

CalcFi Open Data (mirror): 10.6084/m9.figshare.32332290
Freddie Mac PMMS (primary): FRED MORTGAGE30US

Methodology paper

A companion methodology paper is under review at SSRN, describing the ETL approach, the no-imputation rule, the citation-comment-header CSV format, and validation results. When indexed, the SSRN identifier will be appended here.
