I don't know about female/male ratios, but Euronat a G-rated complex is definitely family friendly as is La Jenny. As "you" know, nudism is about de-stressing, relaxing, and returning to innocence. It's about accepting yourself and others for who you are, how you act and what you say rather than what you look like, own, or wear.
Bridget, Children are natural nudists and are taught body shame. Children growing up in nudist households have better body images and fewer body issues and teens have a lower pregnancy rate in comparison with the rest of the population. There have been a number of studies by well-known Sociologists who agree with family nudism.

Mary S. Calderone, M.D., in "The Family Book About Sexuality," states: " ... with very young children accustomed from the beginning to nudity in themselves and their parents, a great deal is taken for granted, and it doesn't seem to be much of an issue to them. What nudity does is make it easy for children to become absolutely certain about just how men and women are made. This knowledge is of great importance in assuring the child of his or her own correct gender. The differences in body states and sizes - and in body organs - can then be taken for granted and will provide an accurate image of how they themselves, or the opposite sex, will look when grown up. Children whose parents feel at ease in such natural events as stepping out of the shower, toweling, and walking back to their room to dress are fortunate."
