We just released the 2025 Communities Need Clinics report. Findings show once again how essential indie abortion clinics are to access in the U.S. #IndiesProvide the majority of abortions & operate the most clinics in states w/ the harshest restrictions. They also provide most later abortion care.

Three Years After Dobbs, the State Divide Over Abortion Deepens
The state divide over abortions has only deepened since the Supreme Court decision. But research shows the number of abortions has climbed.

Shield laws have become a lifeline for abortion patients and providers in the US post-Dobbs, which is precisely why conservative policymakers are turning to the courts, Congress, and state legislatures to attack this critical method of care. 🧵

Are we doomed to a demographic destiny of decline because ladies aren't having babies? No.
We've been here before. It turns out that population projections only describe one of many possible futures. Our actual future is still to be written.

Fears that falling birth rates in US could lead to population collapse are based on faulty assumptions
While the changes in population structure that accompany low birth rates are real, the impact of these changes has been dramatically overstated.

More than 150,000 people traveled out of state to get an abortion last year, nearly one-fifth of whom coming from Texas alone — and new numbers paint a picture of how far they went to receive care.

And as #WeCount and others have documented - the increased availability of telehealth through shield law providers is likely playing a big role here as well: helping many people access abortion care who would have otherwise traveled very far distances or not been able to access care at all.
Florida's ban had ripple effects across the Southeast because in 2023 it was one of the few places where people could access in-clinic care after six weeks. In 2023, more than 1,800 Louisianans had abortions in Florida; in 2024, fewer than 500 did (and most before the ban went in effect in May).
