The Census Bureau publishes estimates of total population and demographic components of change (births, deaths, and migration) for the Commonwealth of Puerto Rico and its 78 municipios. A municipio is the government unit that is the primary legal subdivision of Puerto Rico; the Census Bureau treats the municipio as the statistical equivalent of a county. The reference date for Puerto Rico estimates is July 1.
More detailed estimates and projections for Puerto Rico may be found in the Census Bureau’s International Data Base.
Note: A processing error occurred in the July 1, 2007 Puerto Rico Commonwealth and Municipio Population Estimates, affecting the total population and the number of persons 85 years old and over. As a result, the Population Estimates Branch replaced the Vintage 2007 Puerto Rico Commonwealth and Municipio Population Estimates previously released.
