GBIF biodiversity data coverage index (agent-curated)

GBIF biodiversity data coverage by country (monthly)

Monthly country-level index of biodiversity occurrence-data coverage from the GBIF occurrence search API joined with World Bank 2024 population. For each country/territory with GBIF occurrence records, the connector pulls GBIF's country-faceted counts (all records plus the hasCoordinate=true subset) and joins World Bank 2024 population (SP.POP.TOTL); ISO codes are resolved through GBIF's own country vocabulary with hub.normalize canonicalization, and GBIF's non-territory codes (ZZ/XZ) are dropped loudly. Each row carries occurrence counts, georeferenced share, global share, records per 100k inhabitants, and a documented 0-100 coverage_score = min-max of log10(records per 100k), ranked as coverage_rank, with data-gap (bottom-quartile per-capita), low-georeference (<50% with coordinates), and small-population (<100k) flags. Month-granular as-of stamping makes same-month re-runs hash-identical; every row carries its exact GBIF and World Bank query URLs. Primary key: (snapshot_month, country_code). Caveats: GBIF counts measure digitized/published records, not true biodiversity — high scores mean strong digitization effort; microstates top the per-capita ranking (flagged); month-to-month deltas mix real growth with publisher backfill; 34 economies (incl. Taiwan, 26.4M records) have no World Bank 2024 population and carry NULL per-capita metrics. Only aggregate counts are stored (factual statistics); GBIF.org citation and World Bank attribution required. Sample use: order by coverage_rank for the best-digitized countries, or filter data_gap_flag = 1 for under-documented countries.
