Hello, I’m curious if NHGIS provides PUMA-level summaries for 1 year ACS / decennial data. I know I can download the corresponding microdata from IPUMS USA, but I need it for 2000, 2005-2019. Even for a modest set of variables, this means the data file is roughly 1 gigs compressed.

I looked around NHGIS, but it seems like only 5-year PUMA-level tables are available, am I mistaken?

Thanks!  
Kelsey

Dear Kelsey,

NHGIS does have 1-year PUMA-level summaries for the ACS from 2010-2022 (the more recent 1-year ACS that’s been released). You can find these summaries in the 1-year ACS datasets, which can be found using the following steps:

1. Open the DATASETS filter
2. Click the AMERICAN COMMUNITY SURVEY tab along the left hand side of the pop-up
3. You’ll now see all the ACS datasets we have. Look for the YYYY\_ACS1 datasets in the list.
4. Click the check box next to the 1-year datasets you want
5. Click the SUBMIT button to apply your selections
6. Select the data tables you want

We don’t have the 1-year ACS summary files from 2005-2009. If you’re an R user, I believe Kyle Walker’s [tidycensus](https://walker-data.com/tidycensus/index.html) package provides access to the 2005-2009 1-year ACS datasets via the Census Bureau’s API.

Sincerely,  
Dave Van Riper

Dear Kelsey,

Happy to help!

I forgot to add one other thing to my initial message. The Census Bureau did not publish summary statistics for PUMAs in the 2000 Decennial Census. They only started publishing PUMA-level summary statistics when they rolled out the ACS. Thus, you would have to generate your own summary stats for the 2000 decennial.

Sincerely,  
Dave
