answer:I think the reasons are deeply personal to each mother, and that no single answer will yield a proper or satisfactory explanation. Having said that, here are my list of possible reasons... Why would an abortion be chosen over permitting the full term and delivery, then adopting the child out. Possible reasons: 1. The child was conceived against the mother's wishes (e.g., result of rape, sexual abuse) 2. The mother fears the 'stigma' of an unwanted pregnancy, which can't be hidden if the child is brought to full term (e.g., young, unmarried girl who is afraid of her family's reaction, or societal reaction) 3. The mother believes she will not be able to care for the unborn child properly during the nine months of pregnancy due to lack of support 4. Genetic tests during pregnancy show that the unborn child will not be normal even though it will survive full term (e.g., Down's Syndrome) Then why are so many more pregnancies ending in abortion than adoption? Possible reasons: 1. It's now less of stigma to have an abortion than it used to be 2. It's now easier to have an abortion than it used to be 3. It's now 'safer' (i.e., less of a health risk) to have an abortion now than it used to be
