In just a few days, Missouri could become the first state in the country with zero abortion clinics. But several other states are just one closure away from that fate.

Six states are now down to one abortion clinic – Kentucky, Mississippi, Missouri, North Dakota, South Dakota and West Virginia, according to the Guttmacher Institute, which advocates for reproductive rights.

In most other states, the number of abortion clinics keeps dropping.

As states across the country add more restrictions on abortion access and facilities, clinics have shut down under the weight of heftier regulations, threats to doctors’ safety and violence.

Missouri’s lone clinic that provides abortions – Reproductive Health Services of Planned Parenthood of the St. Louis Region – is suing state officials because the state refuses to renew the clinic’s license that allows it to perform abortions.
