Demographic and economic analysis of catacomb population with regard to the model of historic development

The paper discusses some problems of historic demography in the North Pontic zone. Special stress is made on investigation of evolution in population number, structure, density, changing models of population growth, and the role demographic factor played in the historical process. New ideas in the field of demographic economy are applied to the investigation of producing economy in the steppe zone of Eurasia. The author points to significant disproportions in sex and age structure of the groups during the transition to this type of economy in arid zones, which in the Eneolithic and Bronze Age often resulted in formation of early nomadic economic models.
