This question is loaded with a lot of cultural, racial, and socio-economic factors even though the decision to have an abortion is a very individual one that cannot just be answered quickly. People are hesitant about getting abortion for a variety of reasons, but most point to the ethical implications behind having an abortion.
Some people believe life begins at conception and others believe that life occurs sometime soon after. No one has really answered the question of when life actually begins and so many believe that to have an abortion traverses ethical and moral boundaries.
Many religious denominations frown upon any type of birth control and so having an abortion is definitely considered outside the norm of accepted behavior. With the concept of heaven hell looming over their heads, many women do not want to face eternal damnation for making a decision that would conveniently remove the burden of custodial and emotional care of another human being. Instead, they are hesitant because either way they will face some type of burden, emotional or otherwise.
Socioeconomic factors can also make women hesitant about going through with an abortion. Women temper the costs to have an abortion (which is expensive) with cost to raise a child (which is even more expensive) and weigh their options. Then, there is the relationship that the woman has with the baby’s father, which can also play a factor in deciding whether or not to have an abortion.
There are so many reasons women are hesitant to have abortions, and the above reasons can stand alone or can be combined with the others. Either way, the decision to abort a child is never easy.
