It's not just here, all over the developed world, traditional catholic countries where women once would have had lots of children have decided for a number of reasons not to follow the route previous generations of women took. Umpteen factors, women now have the freedom to control how many children they have, often opting for one or two or possibly none, sometimes a fulfilling career will be more important to her than starting a family, possibly the restraints brought with having children no longer appeals. There are of course umpteen financial factors. Young people throughout Europe are finding it harder to set up independently and have their own home, often two incomes are vital to the household. Maybe the window of opportunity to plan a family doesn't present itself, possibly women leave it too late. Finally, couples may well look at the state of the world and think to themselves "why would I want to bring a child into this mess, we'll get a dog instead."
