Where are the 1940-1960 Puerto Rico samples?

Hi, I’m on the select samples page (https://usa.ipums.org/usa-action/samples?) for Puerto Rico and I don’t see the samples for 1940-1960. I was wondering if I could locate this data somewhere else?

I’m sorry to report that the US Census Bureau never actually made public use Puerto Rico samples for pre-1970 censuses. The Minnesota Population Center’s Historical Census Project created the 1930 Puerto Rico sample while constructing the 1930 10% US sample. The 1920 and 1910 Puerto Rico samples were constructed by the University of Wisconsin, Madison Survey Center. As far as we know there are currently no plans to make the 1940-1960 Decennial Census samples available for Puerto Rico.
