Drawing on a few decades of research, this paper shows that banning abortion would severely harm women in the state, especially women of color and women with low incomes. The paper summarizes research showing that the inability to secure an abortion harms women’s physical and mental health, makes it harder for them to secure an education, reduces their prospects for employment and good wages, and is likely to leave them facing hardship and poverty. The paper concludes that the combined direct and indirect effects of a total ban on abortion in Pennsylvania would likely reduce wages in the state by $10 billion a year.
