It’s possible that 51 could be the new 50. On Tuesday, Nov. 6 amidst all the election kerfuffle, voters in Puerto Rico, passed a referendum in favor of U.S. statehood.

Results showed 65 percent voted in favor of U.S. statehood with 31 percent in opposition, instead favoring a sovereign free association and four percent favoring full independence.

It is not clear whether Puerto Rico will become the 51 state as congressional approval is necessary. Congress faces a few decisions when considering approval, such as the integration of the spanish speaking majority of the territory with the english speaking majority of the continental United States.

In the past Puerto Rico has voted three times on possible statehood, in 1967, 1993 and 1998. All three times Puerto Rico has voted in favor of retaining their territory status. However, according to the Pew Hispanic Center, as of 2009 more Puerto Ricans are living in the United States over the island itself.
