It contributes to the tourist industry in the Lake District and Norfolk Broads areas of England, where many of the books are set. There are also several societies dedicated to the study and promotion of Ransome's work which are largely inspired by the series. The first one to be founded was the Arthur Ransome Club in Japan.

Swallows and Amazons series discussion and theorising about precise relationships. This contributes strongly to the series' air of authenticity. The first book, "Swallows and Amazons", and four sequels — "Swallowdale", "Winter Holiday," "Pigeon Post" and "The Picts and the Martyrs" — are set in and around an unnamed lake in the English Lake District. Most of the unfinished "Coots in the North" would also have been set on the lake had Ransome completed it before his death. The lake and the surrounding fells are based on an amalgam of Windermere and Coniston Water, places where Ransome spent much of his childhood and later life.
