Each editor counted once at this entity (composite identity key). Gender is inferred from the first name — not self-reported — and coverage drops for non-Latin-script names, which inflates the "unknown" bar in some countries.

Board diversity

Per-editor diversity indicators. Each editor is counted once (composite identity key). The Shannon columns use Pielou's normalisation J = H / ln(k) so values are comparable across entities with different numbers of categories. See the methodology for full definitions, use cases, and references (Shannon 1948; Pielou 1966; Jost 2006).

0.405
Pielou's J over ROR country distribution. 0 = all editors from one country, 1 = perfectly even across every country present. MDPI sits higher than Elsevier here; compare against the top-countries bar to see which countries drive the spread.
0.898
Pielou's J over OpenAlex scientific fields. High values mean this entity's editors span many disciplines (a broad multidisciplinary footprint); low values mean they cluster in one field. Especially informative for institution pages, where the country and org_type Shannons are trivially zero.
0.504
Pielou's J over the ROR org_type field (education, healthcare, facility, government, nonprofit, company, archive). Low values mean editors come overwhelmingly from one kind of institution — usually universities, which account for about 82% of editors dataset-wide. Higher values indicate editorial boards that reach into clinical practice, public labs, industry, or scientific societies.
38 yr
Median years since first OpenAlex-indexed publication, per unique editor. IQR 25–50 yr (spread 25 yr), mean 38 yr, n = 1,886. A low median with a small IQR indicates a board clustered in one career stage; a large IQR signals generational mix.
