An annual US poll has found that 75 percent of respondents want "substantial" restrictions on abortion access even as more than half of respondents describe themselves as "pro-choice."

Conducted by the Marist Poll at Marist College, the survey of 1,066 adults on January 8-10 revealed that respondents would welcome limits on abortion so that it can be performed only during the first three months of pregnancy.

Even 61 percent of "pro-choice" respondents favoured such a restriction. Unsurprisingly, 96 percent of respondents who identified as pro-life supported such a restriction.
