USA vs. International Sampling Procedures

Hello, I would like to confirm that the US 1860 1% sampling method is the same for IPUMS International as it is for IPUMS USA? I could only find the sampling description on the IPUMS USA site, which is why I ask. Thank you!

In both IPUMS USA and IPUMS International, the US 1860 1% sample is sourced from the United States Census 1860. The sampling description for IPUMS USA is located here and the sampling description for IPUMS International is located here. You can read here about the 1860 Census sample design.
