How could I have access to the 1940 Preliminary Complete Count Data? I could not find where it is.
On the IPUMS USA homepage, select Get Data. This will bring you to the online data extract system. Click the “Select Samples” button and navigate to the “USA FULL COUNT” tab. Here you will see the available full count files listed. Select the check box for the 1940 full count file and click “Submit Sample Selections”.
