Shapefiles of Mexico (AGEBs, Manzanas, etc)

My post on how to download electoral shapefiles proved to be very popular, so I decided to create another script to download shapefiles of census geographies. This is all data that is freely available from the INEGI website, it’s just that they make it really hard to find, it’s only downloadable as a compressed windows executable, and the download links for the files tend to change every few months.

The shapefiles are encoded as codepage 1252 and were reprojected to WGS84. All data corresponds to the 2010 census.


Now for the ugly bits: You’ll need a recent version of innoextract, one that can work with files created by version 5.5 of Inno Setup (yes, the INEGI distributes shapefiles as windows installers), the one in Ubuntu universe is not recent enough. The version available at this repository should work.

sudo add-apt-repository ppa:arx/release
sudo apt-get update
sudo apt-get install innoextract
chmod +x download-census-shp.sh

As of now, this script has not been tested on Windows and Mac systems, only on Ubuntu. This script has been tested on Ubuntu, on a Mac you should try and use ‘brew install wget’ and ‘brew install rename’ before running it, and on Windows use cygwin. The script will create a directory called ‘shps’ where all the shapefiles are located, if something goes wrong when downloading be sure to delete it and try again. Once you finish running the script you’ll end up with about 5.5 gigabytes of shapefiles containing all available levels of geographical granularity for the 2010 Mexican census.

Census Geographies:
States -> Municipios (Counties) -> Localidades (Polygon if urban otherwise point) -> AGEB (Census Areas - Urban only) -> Manzana (Census Blocks - Urban only)

Plus, you’ll also get a bunch of shapefiles of parks, rivers, schools and so on.


States

Municipios (Counties)

Localidades (Urban Polygons and Rural Points)

AGEB (Census Areas)
Federal District

Manzanas (Blocks)
Federal District

Ejes viales (Streets)
Federal District

Servicios A (polygons and lines)
Camellón, Metro Station, Hospitals, Parks, Schools, etc
 (Federal District)

Servicios L (polygons and points)
Bridges, Railways, Tren Metropolitano, Lindero, etc
 (Federal District)

Servicios P (points)
Churches, Schools, Hospitals, etc
 (Federal District)

P.S. You can contact the INEGI and tell them what you think of the way they distribute data.
P.P.S. If you need shapefiles of elevation curves, archeological sites, rivers, etc, try this other script
