BOC PIK Crosswalk American Community Survey (ACS) Puerto Rico (PR)

The American Community Survey (ACS) Protected Identification Key (PIK) Crosswalks are used to link ACS microdata files to other microdata files with a PIK variable.

The ACS is part of the Decennial Census Program. This survey is sent to a random sample of households in the United States and Puerto Rico on a rotating basis.These data previously were collected only in census years in conjunction with the decennial census. Since the ACS is conducted every year, rather than once every ten years, it provides more current data throughout the decade.
