ORDORICA MELLADO, Manuel. Demography in the first years of the 21^st century: a vision towards the aging process. Pap. poblac [online]. 2006, vol.12, n.50, pp.23-35. ISSN 2448-7147.

The objective of the article is to present a description of the world's population historical evolution. Likewise, a brief review of the origins of the Demography is realized. The central axis of the work analyzes the effects of the demographical dynamics compounds on age structure for Mexico's case. Two fundamental characteristics are pointed out: the population's fast growth in active ages and the elder adults' population accelerated growth. It is shown that this phenomenon will be one of the most relevant problems of the 21^st century. A simulation is performed for the possible results of a population policy set before the 1970's decade. The article closes making some considerations on the future population stages.
