“Trigger” laws in 13 states would immediately outlaw abortion in nearly all cases; some make no exception for rape or incest. In addition, 14 other states appear ready to enact bans and more restrictive laws.

To visualize the scope of these laws, let’s look at the roughly 862,000 abortions in 2017, the most recent year of data provided by the nonprofit Guttmacher Institute, which researches and supports reproductive rights.

Twelve percent took place in states that have trigger bans, laws passed that would immediately outlaw most abortions in the first and second trimesters if Roe were overturned. (Those states are already some of the most restrictive.) And 27 percent occurred in states that plan to enact other new restrictions.
