I don't think most of them are. But I think some of them will be.
But I'm not sure I trust an American study on abortions after 20 weeks, nor do I think it's particularly applicable given the difficulty for women to access or fund abortion in the USA, with ability to pay, lack of insurance, and access, all being labelled as contributing factors.
I will note however that one of the quoted studies says:
"Later abortion recipients experienced logistical delays (e.g., difficulty finding a provider and raising funds for the procedure and travel costs), which compounded other delays in receiving care. Most women seeking later abortion fit at least one of five profiles: They were raising children alone, were depressed or using illicit substances, were in conflict with a male partner or experiencing domestic violence, had trouble deciding and then had access problems, or were young and nulliparous."
So, do we want to force women who are mostly either young, in poverty, experiencing domestic violence, depressed, on drugs, or single mothers, to give birth, when they don't want the child, but most likely won't give it up for adoption? Do we think that it will it benefit anyone to criminalise late term abortion? Or would approaching the situation from a health and social support perspective be more useful?
