DENVER (KDVR) — The United States population is evenly split between states that protect abortion access at the state level and those that do not.

A leaked U.S. Supreme Court draft suggests justices could overturn the 1973 Roe v. Wade case that legalized abortion. If overturned, U.S. states would decide their own abortion laws.

Abortion would stay legal in some states. Twenty-two states and the District of Columbia protect abortion access through state constitutions, legislation or court decisions, according to a database from the Center for Reproductive Rights.

Abortion would remain legal in these states barring new action to overturn previous actions.

States where abortion is protected and in states where it is not protected have wide ranges of restrictions and expanded access. New York law protects abortion at any stage of pregnancy for any reason, while Mississippi bans abortions after six weeks of pregnancy.

Colorado is among the states that protect abortion.

It joins the West Coast, Mid-Atlantic and New England.

States that protect abortion access include Alaska, California, Connecticut, Delaware, the District of Columbia, Florida, Hawaii, Illinois, Iowa, Kansas, Maine, Maryland, Massachusetts, Minnesota, Montana, Nevada, New Jersey, New York, Oregon, Rhode Island, Vermont and Washington.

The Southwest, South and Great Plains states have fewer protections.

States that do not protect abortion access include Alabama, Arizona, Arkansas, Georgia, Idaho, Indiana, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Nebraska, New Hampshire, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin and Wyoming.

A slight majority of Americans live in places where abortions are not protected.

In total, 171,367,377 Americans live in states where abortion is not protected, while 160,332,737 live in states where it is.
