npm-registry-census
Author: Dmitriy Semenkevich (dimhold)
This dataset holds the aggregate counts of a census of every name in the npm registry: the crawler walked 4,305,887 names and the registry answered for 4,296,340 of them.
Headline, from the repository: "84.9% of npm packages list exactly one maintainer." "65.8% have not been published to in 2 years or more." "1.74% run code when you install them."
This is a mirror. The canonical home is the Zenodo record and the GitHub repository; criteria, limitations and full tables live there.
- Paper: https://dimhold.by/papers/npm-registry-census/
- Code and full write up: https://github.com/dimhold/npm-registry-census
- DOI: https://doi.org/10.5281/zenodo.22128843
Files
| path | what it is |
|---|---|
data/census-full.json |
all counts from the full census, plus the maintainer histogram and top 50 publishers |
data/census-sample-100000.json |
the same counts for the earlier 100,000 sample |
data/census-slice.json |
the same counts for the published slice |
data/hooks-full.json |
the install hook counts from the second pass |
data/hooks-slice.json |
every 160th candidate of the second pass with its verdict, 2,023 rows |
data/crawl-state.json |
what the crawler recorded: packages written, 404s, failures, throttles, bytes |
data/crawl-status-as-run.md |
the crawler's own progress file as it finished, labels in Russian |
Files ending in .jsonl here are .ndjson in the GitHub repository, renamed so the viewer reads them; the content is unchanged.
How it was produced
Crawled from 2026-08-19 to 2026-08-21 at 25 requests a second and aggregated in one streaming pass; every share in the README is a division of two raw counts in census-full.json. Not mirrored here: data/slice-5000.jsonl.gz, 5,000 raw registry records with publisher account names; it is third party registry metadata and stays in the GitHub repository. The scripts that turn these files into every number are in the GitHub repository.
