The development of social complexity at the Formative period site of Chalcatzingo, Morelos, Mexico, is traced through its effect on the distribution of variability in the anthropomorphic figurines found there. A new methodology for the analysis of stylistic data is applied. The implications of the character and timing of elite developments at Chalcatzingo are placed in the more general context of highland developments in central Mexico. It is suggested that complex society arose in the region primarily as a result of internal processes and that external stimulus from the Olmec area was relatively unimportant.
