Four Puerto Rican status referendums (in 1967, 1993, 1998 and 2012) have taken place in Puerto Rico to determine whether the insular area should become an independent nation (comprising a republic and an associated republic), apply for statehood, or maintain commonwealth ("Estado Libre Asociado") status. Remaining a commonwealth has been the result of the first three referendums. The fourth referendum resulted in a majority being pro-statehood. There was also a 2005 referendum (Resolution 64) to determine whether the Legislative Assembly of Puerto Rico should be restructured (among other changes to become unicameral).
