Abortion Access and Reproductive Health Outcomes

What the evidence says

Distance to a clinic is the best-measured lever on this page. A quasi-experiment using Texas clinic closures finds that increasing travel distance from 0 to 100 miles decreases resident abortion rates by 29.8%. An increase from 100 to 200 miles decreases them by 18.7%. The mechanism is that distance prevents women from reaching care, at a diminishing rate. The same author's simulation of a Roe reversal with all high-risk states banning abortion predicts a 32.8% fall in the national abortion rate (95% CI 25.9–39.6%) and 93,546–143,561 women prevented from accessing care. The simulation applies Texas distance responses to other regions, so its magnitude is less certain than its direction. A 1996 county panel study finds the same direction for births. A 25-mile increase in distance to a provider is associated with a reduction in teen births of 0.5 per thousand, about 1% of the mean. In-wedlock births fall about 2% and out-of-wedlock teen births rise about 1%. Medicaid funding restrictions are associated with lower teen birthrates, but those estimates are sensitive to specification. The parental consent estimate does not hold up once state-year effects are included.

Evidence on legal restriction as a whole is less aligned. A cross-country model-based comparison finds higher unintended pregnancy rates where abortion is restricted: 73 per 1000 women aged 15–49, against 58 per 1000 where it is broadly legal, in 2015–19. It finds no evidence of lower abortion rates under restriction, at 36 against 40 per 1000. In restricted countries, the share of unintended pregnancies ending in abortion rose 39% (UI 27–53) between 1990–94 and 2015–19. Sources from Madagascar and a policy review state the same pattern: restriction does not reduce abortion, and it increases unsafe procedures. Those two sources cite other studies rather than reporting their own analysis. One source also reports that restricting government funding for abortion services increased abortions and unintended pregnancies. That claim has medium confidence, and the quoted evidence is a summary statement.

The measured harm of unsafe abortion is large and consistent in direction. Global estimates put 45% of abortions as unsafe, out of about 73 million a year. In Africa, 8.3 million of 11.1 million abortions are unsafe. Unsafe abortion is estimated to cause 5.1%–17.2% of maternal deaths in Sub-Saharan Africa. Country figures are 17% in Rwanda, 11.8% in Madagascar (2012), and 7% of maternal deaths across Africa (about 15,000 deaths a year). In Kenya, the share of women with the most severe postabortion complications fell from 37.1% to 17.8% between 2012 and 2023. Mild complications rose from 22.9% to 53.6%. The authors suggest medication abortion availability may be contributing, but they do not test this. Risk factors for severe complications include non-recommended methods (2.56-fold), delayed care (2.03–2.06-fold), food insecurity (1.65-fold), and primary education or less (1.86-fold).

Since Dobbs, abortion volume in the United States has increased, even in banned states. The source attributes this to medication abortion, telehealth, and provider legal protections. Medication abortion is 63% of abortions, telehealth provides 28%, and mailed pills from shield-law states reached 15% by the end of 2024. About 140,000 patients from ban states traveled to access states, and about 100,000 used telemedicine and mail. Telemedicine outcomes are consistent in direction across sources. In a Ghana-region client sample, 96.9% of clients reached for follow-up reported complete abortion. A scoping review reports 6% or fewer needing surgical intervention and adverse event rates from none to 1% or less, with no deaths. Before-and-after records show telemedicine introduction associated with a shift from 46% to 54% medication use in one study. Montana distance fell from 134 to 115 miles. Nevada users rose from 461 to 735. Those comparisons do not rule out concurrent changes.

Evidence on maternal and infant mortality from restriction is thinner. One simulation projects that a nationwide ban would increase maternal mortality by 21% overall and 33% among Black Americans. Baseline CDC data show Black and Indigenous people are two to four times as likely as White people to die during pregnancy or around childbirth. An arXiv study finds a higher infant death risk in states with stricter abortion laws, and a decline in infant mortality after 1970 legalization in three of five income classes. Documented deaths after bans are case reports: six documented by ProPublica, with no denominator or rate. The sources give no measured population-level maternal mortality change since Dobbs.

Access barriers are measured mostly as distance, cost, and information. Among servicewomen, mean travel time to an abortion clinic is 381.7 minutes in the most restrictive states, 118.9 in restrictive states, and 68.7 in somewhat/protective states. Overall, 55.5% face more than 90 minutes of travel. Of US women seeking abortion, 36% lacked coverage for it and 69% paid out of pocket. Medicaid reimbursement covers 37% and 41% of self-pay charges for first- and second-trimester abortions. Online searches from states with fewer clinics return fewer clinic results and more crisis pregnancy center results. These are descriptions of access and information, not measured effects on abortion or health outcomes.

Where the evidence splits

Whether restriction lowers the abortion rate. The distance studies and the cross-country comparison disagree. The Texas-based simulation predicts a 32.8% fall in the national abortion rate under a ban. The cross-country model finds no evidence that rates are lower where abortion is restricted. Post-Dobbs reporting finds abortion volume increased, even in banned states. The claims offer a partial explanation for the post-Dobbs result: medication abortion, telehealth, and shield-law mailing. They do not say whether the Texas simulation modelled those channels. The Texas result is an in-country distance response, and the Bearak finding is a cross-sectional comparison of countries, so the two do not measure the same quantity. Beyond these differences, the split is unexplained by the sources on this page.

Funding restriction and outcomes. One source says restricting government abortion funding increased abortions and unintended pregnancies. A county panel study associates Medicaid funding restrictions with lower teen birthrates. These measure different outcomes in different settings, and the sources on this page do not reconcile them.

Share of maternal deaths due to unsafe abortion. Estimates range from 5.1% to 17.2% in Sub-Saharan Africa. Rwanda is 17% nationally and 12% in 48 public hospitals in 2019. The Rwanda gap has a stated basis: the 12% comes from a hospital-based sample that may not reflect community mortality. The Madagascar source notes that changing measurement methods reduce confidence in its 11.8% estimate. The wider range is unexplained by the sources.

Scale of unsafe abortion. One source gives 25 million unsafe abortions a year. Others give about 73 million abortions a year with 45% unsafe. The sources do not state the reason for the different totals.

Psychological outcomes. A review of Sub-Saharan African studies reports both guilt, sadness, and worry about future pregnancies, and relief, happiness, and satisfaction. Another source states increased risk of anxiety and depression after abortion without appropriate follow-up. Telemedicine users report mixed emotions, with some preferring in-person visits, while 89.4% of clients in another sample would recommend the service. The sources report these as co-occurring and do not quantify their relative frequency.

Thresholds and dose-response

Abortion rates fall with distance at a diminishing rate. An increase in travel distance from 0 to 100 miles decreases resident abortion rates by 29.8%. An increase from 100 to 200 miles decreases them by 18.7%. This comes from Texas clinic closures. The sources do not say whether it generalizes to other regions.

Teen births in a county panel fall about 1% per 25-mile increase in distance to a provider. This is a per-increment rate, not a cutoff.

No other threshold is established in the current sources.

Open empirical questions

• What is the measured change in maternal mortality, rate and not case count, in states with bans since Dobbs? The sources give only six documented deaths and a simulation.
• Does the Texas distance response hold once telehealth and mailed pills are available? The distance estimates come from clinic closures, and the post-Dobbs sources describe workarounds without measuring their offset.
• What explains the difference between 25 million and 45% of about 73 million unsafe abortions a year?
• Did the Kenya decline in severe complications result from medication abortion availability? The authors state only that it may be contributing.
