This article is a partial update of my "Statistics of Word Neighbours" in the November 1997 Word Ways, and provides the facts laying behind the findings in the recent series (August 2000 through May 2001) of articles on word ladders. Two words are neighbours if they differ in a single letter. In this article, each such word is credited as having a neighbour, i.e. the link between them in counted twice (please refer to the earlier article for prior work and more information). The following table updates various parts of the article.
