Puerto Rico Population and Housing Census 1970

The 1970 Puerto Rico de jure census collected data through face-to-face interviews and self-enumeration.

The short form contained questions about household composition and demographics and the long form contained questions on education, migration, employment, income, and fertility. The census day was April 1, 1970.
