(CNN) Here's a look at the Commonwealth of Puerto Rico, a self-governing US territory located in the Caribbean.
(from the CIA World Factbook)
Area: 9,104 sq km
Population: 3,057,311 (2023 est.)
Capital: San Juan
The people of Puerto Rico are US citizens. They vote in US presidential primaries, but not in presidential elections.
First named San Juan Bautista by Christopher Columbus.
The governor is elected by popular vote with no term limits.
Jenniffer González has been the resident commissioner since January 3, 2017. The commissioner serves in the US House of Representatives, but has no vote, except in committees. Gonzalez is the first woman to hold this position.
It is made up of 78 municipalities.
Over 40% of the population lives in poverty, according to the Census Bureau.
Puerto Ricans have voted in six referendums on the issue of statehood, in 1967, 1993, 1998, 2012, 2017 and 2020. The 2012 referendum was the first time the popular vote swung in statehood's favor. Since these votes were nonbinding, no action had to be taken, and none was. Ultimately, however, Congress must pass a law admitting them to the union.
In addition to becoming a state, options for Puerto Rico's future status include remaining a commonwealth, entering "free association" or becoming an independent nation. "Free association" is an official affiliation with the United States where Puerto Rico would still receive military assistance and funding.
