The tremors from Friday’s sweeping Supreme Court decision to strike down Roe v. Wade will ripple across the country almost immediately, with roughly half of all states poised to ban or drastically restrict abortion.

Thirteen states will outlaw abortion within 30 days with “trigger bans” that were designed to take effect as soon as Roe was overturned. These laws make an exception for cases where the mother’s life is in danger, but most do not include exceptions for rape or incest.
