Spanish Colonial Census

Puerto Rico was under Spanish colonial rule from the 1500s until 1898. During this period, Spanish authorities conducted population counts called padrones — annual registers recording residents by name, age, sex, and social status. These records predate civil registration and are among the earliest documentary sources for Puerto Rican family history.

The primary repository for Spanish colonial government records is the Archivo General de Puerto Rico (AGPR), which holds materials from the 1700s through 1898. Holdings are not fully digitized; researchers may need to contact the AGPR directly to access physical records.
