Benford's Law is a logarithmic probability distribution function used to predict the distribution of the first significant digits in numerical data. This paper presents the results of a study of the distribution of the first significant digits of the number of articles published of journals indexed in the JCR Sciences and Social Sciences Editions from 2007 to 2011. The data of these journals were also analyzed by the country of origin and the journal's category. Results considering the number of articles published informed by Scopus are also presented. Comparing the results we observe that there is a significant difference in the data informed in the two databases.
本福特定律是一种对数概率分布函数，用于预测数值数据中首位有效数字的分布。本文呈现了一项关于2007年至2011年被《期刊引用报告》科学版和社会科学版收录的期刊所发表文章数量的首位有效数字分布的研究结果。这些期刊的数据还按原产国和期刊类别进行了分析。还呈现了考虑由Scopus提供的已发表文章数量的结果。比较结果时我们观察到，两个数据库中提供的数据存在显著差异。
