Abortion policy in the United States is now set primarily at the state level, producing sharply different legal regimes across the country. The disagreement is fundamentally about moral premises, which is why it has proven durable against factual argument alone.
For roughly half a century, federal constitutional doctrine established a nationwide framework limiting state restrictions. That doctrine was overturned in 2022, returning primary authority to states and legislatures.
The resulting landscape ranges from near-total prohibition to explicit statutory protection, with many states in between. Related questions have followed: interstate travel, medication abortion by mail, exceptions for life and health, and fertility treatment.
Public opinion has been comparatively stable and does not map cleanly onto the two organized positions. Substantial majorities support legality in early pregnancy and greater restriction later, with wide variation depending on circumstances and question wording.
