Population Dynamics Virtual Lab
Before civilization began to impact the human life cycle approximately 10,000 years ago, human beings had high birth and death
rates. Today the world is in the midst of a demographic transition
a transition to low birth and death rates
as the ability to
control both disease and reproduction increases. Along the way, between these extremes, populations go through an intermediate
period of continued high birth rates, combined with low death rates, resulting in a population explosion.
Because countries span a continuum along this transition, looking at the present demographics of countries around the world provides
an opportunity to look forward or backwards in time: a post-transition country can get a glimpse of a situation resembling its own past
from countries still in transition, and a transitional country may get a hint of its demographic future from countries that are further
along the continuum.
