| # DataCite affiliation usage distributions |
|
|
| Category DOI-affiliation pair totals are sums of per-affiliation DOI counts. |
|
|
| An occurrence count is the number of normalized DataCite occurrences for an affiliation. DOI count is the number of distinct DOI-affiliation pairs for an affiliation. The raw affiliation count is the number of pre-normalization affiliation rows represented by an affiliation. |
|
|
| individual DOI prevalence = datacite_doi_count / total_distinct_datacite_dois |
| |
| Category DOI-affiliation pair totals are not mutually exclusive unique DOI populations. |
| |
| Distribution percentiles use DuckDB quantile_cont with Type 7 continuous interpolation. |

| ## Full-population concentration |
|
|
| Occurrences and DOI-affiliation pairs are ranked separately. Boundary ties use normalized-affiliation ascending order and do not expand a requested row count. |

| ## Most common explicit ROR IDs |
|
|
| The tables show the first 20 of the 100 retained JSON ranking rows. ROR DOI support counts distinct DOIs and can sum above valid-assigned DOI-affiliation pairs when one pair has different IDs across occurrences. |
