Curated NaNDA datasets (20)
Curated: Datasets that went through ICPSR's full curation pipeline. Curated releases ship with documentation, codebooks, and per-month usage breakdowns; they live at icpsr.umich.edu and report unique users, institutions, and citing publications.
Showing 20 of 20 curated studies
Change values are total downloads from May 12, 2026 to May 13, 2026 (the previous monthly snapshot to the latest). A dash (—) means no comparable prior value.
Self-published NaNDA datasets (30)
Self-published: Datasets self-deposited via openICPSR. Self-published releases skip the full curation pipeline, so usage reporting is limited to total downloads and total project-page views — no per-month breakdown, unique-user count, or publication tracking.
Showing 30 of 30 self-published studies
Change values are total downloads from May 12, 2026 to May 13, 2026 (the previous monthly snapshot to the latest). A dash (—) means no comparable prior value.
Unpublished NaNDA datasets (55)
Unpublished: Datasets in NaNDA's inventory marked status=unpublished — openICPSR deposits that are not part of the current published release set (typically older or superseded versions). Usage reporting matches self-published: total downloads and total project-page views only, no per-month breakdown.
Showing 55 of 55 unpublished studies
Change values are total downloads from May 12, 2026 to May 13, 2026 (the previous monthly snapshot to the latest). A dash (—) means no comparable prior value.
How this is calculated
Show methodology
Numbers are aggregated lifetime totals since January 1, 2020, pulled monthly from ICPSR's PCMS APIs (curated datasets) and the openICPSR usage endpoint (self-published datasets). Curated entries report data and documentation downloads, unique users, and citing publications. Self-published entries report total downloads and total project-page views only — openICPSR does not expose a per-month breakdown. The dashboard is rebuilt automatically on the first of each month from the latest scrape.
Source code, raw CSVs, and the full schema are on the dashboard's GitHub repository.
