I was trying to link the raw data from the IPUMS USA website for Puerto Rico to the PUMA GIS shapefile. However, in the raw data extracted from this website there are 30 list of PUMA codes for Puerto Rico, while the GIS shapefile of PUMA from US census website only gives 27 PUMAs. Furthermore, the PUMA codes do not match.For example, in the GIS shapefile, the PUMA codes starts from 00101, 00102, to 01101, 01102, while the PUMA codes from this website https://usa.ipums.org/usa-action/vari… have different codes, which goes from 00100, 00200, to 02500 and 02600 consecutively. Could you help me look into this?
Furthermore, do you know where to download the PUMA GIS shapefile? I used the ftp address ftp://ftp2.census.gov/geo/tiger/TIGER…, but you may know better place than this.
