A question about January 2025 revision of US full count census

According to the January 2025 update of the full-count census on this link ( IPUMS USA ), alternative string variables for the names have been added to your “database”. Does this mean this particular update of name variables applies to 1940 census or all the other censuses?

Thank you!

The changes described on the full count data page under the heading “January 2025 - 1940 Full Count File,” including the changes to the name variables, apply only to the 1940 full count data.
