Legislative attacks on abortion have been so numerous in 2021 that it may be considered the most devastating period for reproductive rights on record, a report released Friday found.

New findings from the Guttmacher Institute, a pro-choice research and policy organization, put the number of abortion restrictions introduced in state legislatures at 536 across 46 states, touching nearly every corner of the U.S.

Of those restrictions, 146 attempted to outlaw abortions, either through outright bans on the procedure or through bans imposed after a limited number of weeks into a pregnancy.

So far, lawmakers have enacted 61 of those restrictions across 13 states, including eight bans. That number is unheard of, said Elizabeth Nash, a principal policy associate for the Guttmacher Institute who co-authored Fridays report.

It is not unusual for hundreds of abortion restrictions to be introduced in state legislatures each year, she told HuffPost. But this year we are seeing a high volume of restrictions getting signed into law and a wide scope in the types of legislation, including near-total abortion bans that should be relegated to the dustbin of history. The sheer volume of enactments so far this year is unprecedented. And theres many more still gaining traction.
