This paper is frankly exploratory, designed to test the possibility of applying historical and archaeological evidence to the solution of certain problems in demography and human ecology for which it is impossible to secure data of more conventional character.
The Central Mexican region was selected because it contained for a very long time perhaps the densest population on the North American continent and because the annalistic as well as archaeological information concerning it is remarkably copious. Specifically the area is defined for present purposes as that included in the present states of Vera Cruz, Hidalgo, Tlaxcala, Puebla, Mexico, Federal District, Morelos, Oaxaca, Michoacan, and Guerrero. This territory is not an ethnic or economic entity since it includes both coastal and highland cultures together with numerous independent linguistic stocks. On the other hand it corresponds to the most intensive area of archaeological investigation outside of Yucatan and is more or less coterminous with the so-called “Aztec Empire” as the latter existed in 1520.
