In the early 21st century many organised clubs saw a decline in attendance by young people, which worried many naturists about the future of the movement. The clubs' aging memberships may have put younger people off joining in a vicious circle of decline. A rise in social conservatism, re-asserting a nudity taboo, may have also contributed to the decline. However, since tolerance for nudity in general is increasing over time, and is higher among younger generations, an alternative hypothesis is that younger naturists no longer feel they need to join a club or visit a resort in order to practise naturism. Active recruitment of younger members is being pursued by some organisations. The phenomenon varies by country, with, for example, naturism in France experiencing steady growth in a younger demographic during the 2010s.
