Speaking for the UK, it is certainly the case that couples put off having children until they've bought their own home, and the shameful reason for this is that renters have no security of tenure here. Unless you're in state subsided social housing you live with the permanent threat of being turfed out of your home at only two months notice, for no better reason than the landlord wants to do something else with it. Finding a new home and organizing a move is difficult and unsettling enough for a young working couple, but with children involved its on another level, not least because it could well mean a change of school, or result in siblings in different schools.
