state and PUMA shapefile

Hi, I am using the ACS 2015, 5 years est. I am trying to create a US map in Stata by PUMA level but wanted to draw the state lines. To do that I need puma and state shapefiles. I am using the PUMA shapefiles published by IPUMS, but the state boundaries I am getting from the census and they are not congruent with the PUMA shapefiles.

Do you have state shapefiles that I could use with your PUMA shapefiles?

I also tried to use the PUMA shapefiles from the census but the map I get is not good.


Do you have the same question? Follow this Question

IPUMS USA's PUMA shapefiles are based on IPUMS NHGIS shapefiles, which are in turn based on Census TIGER/Line Shapefiles. The link you provided to Census shapefiles goes to their "Cartographic Boundary Files", which are a simplified version of the TIGER/Line files that do not align with the more detailed TIGER/Line Shapefiles or the NHGIS files.

At the bottom of the IPUMS USA Boundary Files page, you'll find a link to IPUMS NHGIS and a summary of the many boundary files available through that site, which includes state-level files. The NHGIS versions will generally align correctly with the IPUMS USA PUMA files.
