If the US Supreme Court overturns Roe v. Wade, which granted Americans a constitutional right to abortion in 1973, each state would again be able to decide whether their residents are legally allowed to have abortions.

While 10 states currently have laws on the books that would keep abortion legal within their borders, 18 states have laws that could make the procedure illegal if Roe falls.

In the decades since Roe, states have also passed laws that have chipped away at abortion access in the US.

Many restrictions have made women's' ability to get an abortion increasingly dependent on where they live or whether they have the means to travel hundreds of miles to the nearest location.

The landmark Supreme Court case Roe v. Wade and subsequent rulings upholding it have granted the right to abortion for Americans since 1973 — but the reality of that right varies dramatically from state to state.

Since Roe became the law of the land, individual state legislatures have enacted dozens of restrictions and regulations to make it as difficult as possible for patients to actually access abortion.

From strict regulations on clinics and bans on abortion after a certain number of weeks, to requiring patients to receive counseling and undergo waiting periods, these laws have tested the limits of Roe — with many ending up in federal court.

The US Senate has confirmed two of President Donald Trump's Supreme Court nominees to give the Court a solidly conservative majority, causing many abortion-rights advocates to fear that such a makeup could result in Roe being overturned altogether.

The more likely scenario, according to legal experts, is for the high court to chip away at abortion rights by ruling in favor of the state-level restrictions that reach their docket — depending on which cases they actually decide to hear.

These seven charts and maps illustrate what abortion access in America actually looks like today, and what could happen if Roe fell.
