Initial release.
aei_releases() lists available Anthropic Economic Index
releases on Hugging Face, blending bundled metadata with a live
listing.aei_files() returns the recursive file tree of a
release.aei_index() fetches the canonical usage CSV for a
release, handling the wide-to-long schema change between the 2025-03-27
and 2025-09-15 releases automatically.aei_download() is the lower-level escape hatch for
fetching any file from a release by path.aei_clusters() returns the request-hierarchy tree (Clio
output) as a parsed nested list. Released from 2025-09-15 onwards.aei_tasks() returns the bundled O*NET task statements
(released with the 2025-03-27 snapshot).aei_geography() filters the long-format enriched table
to country or US-state rows. Released from 2025-09-15 onwards.aei_compare() produces a release-on-release diff of the
same metric across two AEI snapshots, returning shared keys plus
value_a, value_b, delta, and
pct_change.aei_link() is a generic merge helper that preserves the
aei_tbl class and provenance metadata. Use it to splice the
AEI to your own data on a shared key (country code, occupational
identifier, cluster name, etc.). Supports left, inner, and full
joins.aei_concentration() computes the Herfindahl-Hirschman
Index, top-N concentration ratios (CR4 by default), and Shannon entropy
on a vector of usage shares. Auto-detects the share column and supports
per-group computation.aei_cite() returns a citation in plain text, BibTeX, or
bibentry form, including the methodological source paper of
Handa et al.
aei_cache_info(), aei_cache_clear(), and
aei_cache_dir() manage the local data cache.aei_tbl class with print,
summary, and [ methods that preserve the
aei_query provenance attribute (release id, source URL,
fetch timestamp) across subsetting.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
