In one of the referendums on the political status of Puerto Rico held in 2012, only 5.49% of Puerto Ricans voted for independence, while 61.16% voted for statehood and 33.34% preferred free association. Another then-recent referendum was held in 2017 with over 97% voting in favor of statehood over independence, though historically low voter turn-out (23%) has called into question the validity of the poll. Much of the low turn-out has been attributed to a boycott led by the pro-status-quo PPD party and the pro-independence PIP party. A 2020 referendum also backed statehood 53 percent to 47 percent, with 55 percent turnout.
