From the abstract:
The 2010 U.S. Census counted 3.7 million people living in Puerto Rico, a territory of the United States. This was down from 3.8 million in 2000.
By contrast, in the 50 U.S. states and the District of Columbia (D.C.), the population of Puerto Rican-origin Hispanics increased from 3.4 million in 2000 to 4.6 million in 2010, surpassing Puerto Rico’s population. Nearly one-third of Puerto Rican-origin Hispanics in the 50 states and D.C. were born in Puerto Rico, according to Pew Hispanic Center tabulations from the 2009 American Community Survey.
People born in Puerto Rico are U.S. citizens by birth. But because Puerto Rico, like Guam and the U.S. Virgin Islands, is not part of the 50 states or D.C., those who reside in Puerto Rico are not allowed to vote for President or to elect a voting member of the U.S. Congress. Those who move from Puerto Rico to live in the 50 states and the District of Columbia can vote in federal elections.
This profile compares the demographic, income, and economic characteristics of Hispanics living in Puerto Rico with the characteristics of Hispanics of Puerto Rican origin living in the 50 states and D.C. as well as with all Hispanics living in the 50 states and D.C. These profiles are based on tabulations of the 2009 Puerto Rico Community Survey and the 2009 American Community Survey by the Pew Hispanic Center. Both surveys provide detailed demographic and economic characteristics that are not available in the 2010 Census. This includes place of birth.
