Research paper topic

A topic I would look into is free birth control in the United States. There have been budget cuts and certain places like planned parenthood, are being taken away or cut back. I want to talk about how much money it costs the government to keep these places funded. I would also like to research statistics on how many teen pregnancies are prevented because of these free birth control facilities. Also, would their be a rise in teen pregnancies if taken away? Would more teen pregnancies cause an increase in the amount of women on welfare or other government based assistance. Would cutting funds in this area help or hurt our government?
