The population of Puerto Rico according to the 2020 census was 3,285,874, an 11.8% decrease since the 2010 United States Census. The commonwealth's population peaked in 2000, when it was 3,808,610, before declining (for the first time in census history) to 3,725,789 in 2010. Emigration due to economic difficulties and natural disasters, coupled with a low birth rate, have caused the population decline to continue in recent years.
