The figures aren't significant, but apparently the number of women devoting their life to god and becoming nuns is on the rise in Britain. http://www.bbc.co.uk/news/magazine-15385144
The article describes a 25-year-old who is looking for something more in life:
Catherine describes herself as "a girly girl" who loves to be pampered. She has also wanted to be a nun since she was four years old.
Like many of her contemporaries, the 25-year-old has spent the last few years travelling, partying and studying for a degree in languages at King's College in London.
She also worked as a model, but for her it was an unfulfilling experience and left her thinking again about devoting her life to God.
Personally I think Catherine is looking in the wrong place to discover something more in life, but hopefully she'll get there some day.
