Population density .

The density of population estimates the number of inhabitants between the surface of the site. In general it is considered that an area is sparsely populated has a density of 10 inha./km2.  And that is a very populated area if the density exceeds 80 inha./km2.

Model of population cycle.

The model of demographic transition progresses in four stages:
Old or preindustrial demographic regime: it is characterized by high mortality rates and birth rates.
First transition: Keep the high birth rate, but mortality drops.
Second transition: the birth rate begins to decline, but mortality is still down more slowly.
Modern demographic regime: Mortality rates and very low birth.
