Puerto Rico, an unincorporated territory of the United States in the Caribbean, has undergone significant demographic changes over the past seven decades. In 1950, Puerto Rico’s population was 2.2 million, and it grew steadily through the 20th century, reaching a peak of nearly 3.8 million in the early 2000s. Since then, however, Puerto Rico has faced a sharp population decline due to migration, economic challenges, and low birth rates. As of 2024, Puerto Rico’s population stands at 3.24 million, reflecting one of the fastest rates of population loss in the region.
Historical Population Growth (1950–2024)
Puerto Rico’s population more than doubled between 1950 and 2000, fueled by natural growth and a relatively high fertility rate during the mid-20th century. However, after 2005, the trend reversed, with consistent annual declines.
