Is there any websites that provide the 1990 or 2000 PUMA Equivalency Files? I can only find the 2010 version on Census Bureau website. UM’s website does provide the data I need but the access to the data is restricted. Thanks in advance.

It sounds like the [information on this forum question](https://forum.ipums.org/t/consistent-pumas-1990/2792) might be helpful to you. In short, The [CONSPUMA](https://usa.ipums.org/usa-action/variables/CONSPUMA#description_section) variable bridges 1980, 1990, and 2000 PUMA definitions and might be helpful for your needs.

I just want to be sure that I understand this.

I’m running an analysis where I compare IPUMS data from 2000 with the 5-Year ACS estimates from 2013-2017. I need to sue the cpuma0010 variable to have consistent pumas across years and I need the cpuma0010 shape file for mapping, which can be found [here](https://usa.ipums.org/usa/volii/boundaries.shtml).

Also, just to confirm my understanding, the [puma](https://usa.ipums.org/usa-action/variables/PUMA#comparability_section) variable does not allow for comparisons between 2000 and my 2017 data because the boundaries changed in 2010 and I need to use the cpuma0010 variable.

Thanks for the help on this.

Yes, Kasey. Your understanding is correct about all of that.
