GIS of Mexican states, municipalities, and islands, 1990, in Arc/Info export format. In this dataset, the boundaries of the Mexican states and municipalites that share borders with the United States are consistent with those from TIGER95. Attributes include selected demographic and socioeconomic variables from INEGI. Files are available through ftp.

The Georeferenced Population Data Sets of Mexico consists of the following products: Population Database of Mexico; Urban Place, Time-Series Population Spreadsheet of Mexico; Urban Place GIS Coverage of Mexico; GIS Coverage of Mexican Localities; GIS Coverage of Mexican States; GIS Coverage of Mexican Municipalities; and Raster Based GIS Coverage of Mexican Population.

Included in the collection are approximately 100,000 records of geographic and census items for Mexican states, municipalities, and localities. The geographic records consist of state boundaries, place names, geographic coordinates of more than 30,000 urban and metropolitan places, and elevation data for more than 700 urban places. The census records contain estimates of 1990 population density, population by gender, and population by age bracket (below 6 years of age, between 6 and 14 years, and older than 15 years). For 706 selected urban localities, the population is traced back by decades, from 1990 to 1921, based on census documents.
