Election Facts About Puerto Rico

Characteristics of Puerto Rico’s Eligible Voter Population

  1. In this fact sheet, eligible voters are defined as U.S. citizens ages 18 and older. Eligible voters are not the same as registered voters. To cast a vote, in all states except North Dakota, an eligible voter must first register to vote.
  2. The terms “Hispanic” and “Latino” are used interchangeably. Since over 98% of Puerto Rico’s population is of Hispanic origin, statistics for Puerto Rico’s combined Hispanic and non-Hispanic populations are shown.
  3. The specific data set used to derive estimates contained in this fact sheet are from the University of Minnesota’s Integrated Public Use Microdata Series (IPUMS) for the 2006 Puerto Rico Community Survey (1% sample). Information can be found on the following Website: The estimates in this fact sheet are subject to sampling error.
