The US Department of Homeland Security, Homeland Infrastructure Foundations - Level Data (HIFLD) published spatial data set describing the locations of pharmacies and medical supplies in the United States. This feature class/shapefile contains pharmacies found in the US territories of Puerto Rico. A pharmacy is a facility whose primary function is to store, prepare and legally dispense prescription drugs under the professional supervision of a licensed pharmacist. It meets any licensing or certification standards set forth by the jurisdiction where it is located. The tabular data was gathered from the National Plan and Provider Enumeration System (NPPES) dataset. Pharmacies that were verified to service only animal populations were excluded from the dataset. The records within this dataset was compiled between 2010-03-30 through 2010-10-25.
