<span class="mw-page-title-main">Puerto Rico statehood movement</span> Movement to grant Puerto Rico U.S. statehood

The Puerto Rico statehood movement aims to make Puerto Rico a state of the United States. Puerto Rico is an unincorporated territorial possession of the United States acquired in 1898 following the Spanish–American War, making it "the oldest colony in the modern world". As of 2019, the population of Puerto Rico is 3.2 million, around half the average state population and higher than that of 20 U.S. states. Statehood is one of several competing options for the future political status of Puerto Rico, including: maintaining its current status, becoming fully independent, or becoming a freely associated state. Puerto Rico has held six referendums on the topic. These are non-binding, as the power to grant statehood lies with the US Congress. The most recent referendum was in November 2020, with a majority (52.52%) of those who voted opting for statehood.
