Hello,
I recently helped a student who was looking for data for Mexico (and
neighboring countries), so I have a long annotated list of data
(basically what I provided for the patron). My patron's research area
was much larger so this may not even help since these layers are
probably too small scale. But just in case I thought I'd share.
ArcGIS Online has highway-level roads data
http://resources.esri.com/arcgisonlineservices/index.cfm?fa=home
General base data layers for Mexico are available from ESRI Data & Maps
(the latest is ESRI Data & Maps 2008).

Data on Population/Urban Areas
SEDAC from Ciesin has Mexico data
http://sedac.ciesin.columbia.edu/gateway/guides/usmex_census.html
The data was published in 1999 but contains census data from 1990. Data
is by municipio, state, and island. The island data is a point layer.
The others are polygons.
Island data: mexisl
Municipios: mexmunic
States: mexst
Attributes include total pop, male and female. Data is in GCS, Clarke 1866
Urban Places
Includes attribute of population from Pop 1921, Pop 1930, Pop 1940, Pop
1950, Pop 1960, Pop 1970, Pop 1980, Pop 1990
urbmex
Feature Class: point
Urban Place GIS Coverage of Mexico is a vector based point Geographic
Information System (GIS) coverage of 696 urban places in Mexico. Each
Urban Place is geographically referenced down to one tenth of a minute.
The attribute data include time-series population and selected
census/geographic data items for Mexican urban places from from 1921 to
1990.
source:
http://sedac.ciesin.columbia.edu/gateway/guides/geomex_urbanplace.html
There is also a raster dataset of population, "RASTER BASED GIS COVERAGE
OF MEXICAN POPULATION"
This data contains cell population and population density by grid cell.
Grid cells are 1km x 1km
http://sedac.ciesin.columbia.edu/gateway/guides/geomex_rasterpop.html
Raster: agridnone
**************
Poverty Data
There is data for Mexico and Honduras available for download from the
Poverty mapping project.
http://gisweb.ciat.cgiar.org/povertymapping/
There are a lot of socioeconomic indicators in the attributes like
education, percentage of households with a phone, etc.
metadata:
http://gisweb.ciat.cgiar.org/povertymapping/metadata/mexicocasstudy_faq.htm
**************
Landuse Data
(Although it is not high-resolution)
Link:
http://www.fao.org:80/geonetwork?uuid=048b70f0-0576-11dd-af4e-0017f293bd28
Abstract:
Beta version of a thematic grid of Land Use Systems (LUS) and its
attributes for Latin America and Caribbean with a spatial resolution of
5 arc minutes or 0.083333 decimal degrees. This dataset, presented as
beta version, is developed in the framework of the LADA project (Land
degradation Assessment in Drylands) by the Land Tenure and Management
Unit of the Food and Agriculture Organization of the United Nations and
is copyright of FAO/UNEP GEF. The LUS map implementation is based on a
innovative methodology combining more than 10 global datasets. Due to
the map generation method, the quality of the map can never be uniform.
The overall quality of the map depends heavily on the individual quality
of the data for the different countries.

Other Suggestions
Here are some suggestions on places for you to continue your search for
data.
Sites in Spanish:
INEGI is the official mapping agency of Mexico.
http://www.inegi.gob.mx/inegi/default.aspx
They have a mapping service:
galileo.inegi.org.mx <http://galileo.inegi.org.mx>
It can be accessed through ArcCatalog, but there are only image services.
The Pan American Institute of Geography and History:
http://www.ipgh.org/spanish/default.htm
***
The Earth Observation Group has Nighttime Lights of the World, including
a change pair 1992-1993 and 2000.
They also have a Global Impervious Surface Area data layer and global
poverty estimates.
http://www.ngdc.noaa.gov/dmsp/download.html
There is a landscan dataset you may be interested in for population:
http://www.ornl.gov/sci/landscan/

I would be very grateful if someone could tell me where one can
obtain a reasonably up-to-date shapefile with streets (and maybe
other geographic features) for Nogales, Mexico. Thanks.
